Having trouble getting your LED lighting project approved because of cost? That said, a very broad spectrum of CRI values is available ranging generally from 65-95. Topics: Discussion in 'Grow Room Design/Setup' started by Headhunterpipes, Feb 19, 2020. The need for reflection and redirection of light means that the output is much less efficient for omnidirectional lights due to losses than it would be for the same light if it were directional by its nature. For an interesting take on the history of street lighting in the United States read here. 315W Systems - Ceramic Metal Halide Light Kits (CMH) - Grow Lights HID grow lights analysis. Keep track of … Ceramic Metal Halide grow lights are basically a variation of MH grow lights with a little of HPS added into the mixture. These are CMH or Ceramic Metal Halide Grow Light. Because LED lights typically operate with multiple light emitters in a single luminaire the loss of one or two diodes does not mean failure of the entire luminaire.. Metal Halide lights exhibit an end-of-life phenomenon known as cycling where the lamp goes on and off without human input prior to eventually failing entirely. LEDs fail by dimming gradually over time. Diodes are generally made from semi-conductive materials such as silicon or selenium - solid state substances that conduct electricity in some circumstances and not in others (e.g. Metal Halide lights have average efficiency (75-100 lumens/watt source efficiency). Additionally, metal halide bulbs are inefficient energy consumers. LEDs are an ideal light for purposely turning on and off because they respond rather instantaneously (there is no warm up or cool down period). High pressure sodium grow lights produce up to 40% more lumens per watt than metal halide lights, and this then leads to much higher yields when marijuana is flowering. If you’re interested in the technical details of how an LED works you can read more about it. They produce steady light without flicker. Typical preventive measures include changing bulbs prior to their expected end of life and as a group (versus spot changing single bulbs that actually fail). Regardless of the type of high bay light you choose, they all offer excellent light coverage with quality brightness for an expansive space. Full spectrum LED, Metal Halide, HPS and CFL bulbs 600W - 1000W for all plant requirements! LED efficiency drops as current increases. These metal halide lamps contain more mercury (more than twice) compared to HPS lamps on an average. These filters are required to prevent fading of dyed surfaces exposed to metal halide light otherwise serious damage can occur to light fixtures or even human beings and animals (e.g. The only real potential downside to this is when LEDs are used for outdoor lighting in wintery conditions. Metal Halide lamps produce light by passing an electrical current through a mixture of mercury and Metal Halide gas. The reason for this is simple: due to their customizability, LED lighting solutions make for more efficient grow lights than high-pressure sodium lamps. They lower heat also means no burn damage to plants —in many cases, even when there is extended leaf-on-bulb contact. A big advantage of LEDs over metal-halide grow lights is their significantly lower heat output. Industrial Lighting, Learn the pros and cons of using LED or HPS/metal halide for cannabis growing. The quality of your grow light is the single most important tool an indoor gardener can use to increase the quantity and the quality of their crop. Most values for LED system efficiency fall above 50 lumens/watt. Individual LED chips produce very narrow spectrum bands, so LED grow-lights can be precisely mixed to deliver a spectrum that is optimized for maximum plant absorption and utilization. The technology pays the investor back over time (the payback period). LED lights are not compatible with traditional incandescent dimmers (which lower the voltage sent to the light) so you need to purchase LED dimmer switches as well if you want to dim. Heat output also increases with additional current which decreases the lifetime of the device. LED grow lights, on the other hand, require less electricity to run and, due to their lower production of excess heat, less electricity to keep down the temperature of the grow space. The ultimate purpose of the device is to emit light, not heat. Metal Halide Notes. Lumens Efficiency. The first practical use of LEDs was in circuit boards for computers. LEDs produce a very narrow spectrum of visible light without the losses to irrelevant radiation types (IR, UV) or heat associated with conventional lighting, meaning that most of the energy consumed by the light source is converted directly to visible light. Note: recent advances in LEDs will likely improve their droop qualities. New LEDs can last 50,000 to 100,000 hours or more. When current is applied to the MH bulb, the tube glows like the sun. What is the better choice between LED vs HID grow lights? Metal halide grow lights are about five times as energy efficient as an incandescent bulb, with a usable life span of about two years of 18/hour daily use. Prism Lighting Science Ceramic Metal Halide: Best versatility. Hazardous Location Lighting, Lastly, Metal Halide grow lights usually tend to last for a longer period of time when compared to HPS grow lights.  888.771.4769   [email protected]   Sun Valley, California USA, G8 LED Tips LED Technology All Products My Account FAQ Contact Us, Order Tracking LED Grow Lights Blog Grow Journals Videos Affiliates, Affiliate Program Wholesale Orders Privacy Policy Warranty Policy Return Policy. Since the light that comes out of the two grow lamps is different in colour, the function of the light is also quite different – Metal Halides are useful during the vegetative phase, while HPS lights are more useful during the flowering stage of the marijuana plant’s life cycle. As the lamp ages, the required voltage increases beyond the available source voltage. Improper bulb orientation can actually reduce the life by 5,000 hours. 800-468-9925 Request A Quote It is very much the opposite of a photovoltaic cell (a device that converts visible light into electrical current). The size of the lamps is limited by the wattage and light output required for a given application. The comparison above between High Pressure Sodium grow lights vs LED grow lights clearly indicates that the LED grow lights have a significant advantage when compared to HPS lights. High Pressure Sodium vs LED - What’s The Difference Between High Pressure Sodium and LED Lights. Im talking about the actual power draw, the actual watts that your light pulls out of the wall. Keep track of the bulb’s life so it … The light has a wide spectrum and a good cri that resembles natural light from the sun. G8LED grow light … On top of this, they need to be run for much longer periods of time than actually needed due to the warm-up requirement. Discussion in 'Grow Room Design/Setup' started by Headhunterpipes, Feb 19, 2020. Commercial Lighting, Despite the good return on investment, an LED grow light system has a large, upfront cost. LEDs are the only lighting technology that can be designed to meet specific light spectrums for plants. For this reason in many applications (such as a sporting stadium) metal halide lamps must be changed out prior to the end of their useful life. Typical options can be split into four major categories: fluorescent grow lights (CFLs), metal halide (MH), high-pressure sodium (HPS), and light-emitting diode (LED). That being said, HIDs still represents an established option for many indoor growers. There are two types of HID grow lights, and this is the main topic of our article today – these are HPS grow lights and MH grow lights. In a large-scale building (like a warehouse, hockey rink, or stadium), this inefficiency will really add up. Many metal halide lamps used in warehouses and sports facilities take 15-20 minutes just to reach their normal operating temperature. Metal Halide vs LED (Lumen Comparison) School and University Lighting, 1.0.1 1) VIVOSUN 98% Ultrahigh Reflectivity 315W CMH Grow Light: Highest reflection. Industrial LED Lighting For … LEDs emit very little forward heat. Although this is rare and there are preventive measures that reduce risk, there is still the possibility of injury or damage as a result. This is typically an advantage because light is usually desired over a target area (rather than all 360 degrees around the bulb). The quartz tube also contains halide salts, like silver chloride, that are used to fine-tune the color produced by the bulb. Modern LED lights are engineered to reduce the amount of heat given off, either by use of a heat sink or by diverting heat away from the diodes. Additionally, there is a small risk that a metal halide lamp can explode. Many 400 watt metal halide lights deliver 32000 to 40000 lumens, while numerous manufacturers recommend that their 100 to 150W LED corn light bulbs can replace the 400W metal halide. A CMH uses a ceramic arc tube similar to those used in HPS grow lights instead of the quartz used in traditional metal halide grow lights. 1. This is usually overcome with LEDs by covering the light with a visor or facing the light downward towards the ground. In this way, energy is not wasted and the growth is improved. There is a wide range of fixture cost for HID grow lights. HID grow lights analysis. Metal halide (MH) or high intensity discharge (HID) lighting makes use of a large glass bulb that contains a small quartz tube containing argon gas and a minute amount of mercury. Many 400 watt metal halide lights deliver 32000 to 40000 lumens, while numerous manufacturers recommend that their 100 to 150W LED corn light bulbs can replace the 400W metal halide. Furthermore, LEDs can minimize the portions that are used less. Cons. LED grow lights will give you tremendous electrical savings and will reduce operational costs, providing savings month after month. Lastly, Metal Halide grow lights usually tend to last for a longer period of time when compared to HPS grow lights. High Pressure Sodium bulbs create a more yellow-gold color that’s optimal for the flowering stage, but still effective in the vegetative stage. You can read more about the impact of directional lighting by learning about  a measurement called “useful lumens” or “system efficiency.”. The type of gas used in the bulb determines the color spectrum and wavelength, so if you need a different type of light you have to change the bulb itself. This is by far the biggest downside that needs to be considered. Much of these emissions must be reflected and/or redirected which means losses and lower overall system efficiency. High Initial Setup Cost. Metal halide (MH) or high intensity discharge (HID) lighting makes use of a large glass bulb that contains a small quartz tube containing argon gas and a minute amount of mercury. The quality of your grow light is the single most important tool an indoor gardener can use to increase the quantity and the quality of their crop. These power strips protect your light against irregular voltage fluctuations which can damage electrical devices. Since then they have gradually expanded their applications to include traffic lights, lighted signs, and more recently, indoor and outdoor lighting. But here's the kicker: I'm talking about the real wattage value! LED lights are a wonderful solution for gymnasiums, warehouses, schools, and commercial buildings. 1. LED vs Metal Halide What are LEDs? LED lighting has relatively high initial costs and low lifetime costs. Grow lights are typically the most overlooked and underappreciated aspect of an indoor garden. Overall that means very high maintenance costs over time. Grow Co. 630w Ceramic Metal Halide is one of the most popular CMH lights in the market. Best Led Grow Lights Flower Booster Led Kit Full Spectrum Led Grow Lights, G8 Led Veg Light Indoor Led Grow Lights Led Grow Lights. The built-in timers are a nice touch and will eliminate the need to get a separate timer. Since then they have gradually expanded their applications to include traffic lights, lighted signs, and more recently, indoor and outdoor lighting. Ever wonder how metal halide lights and light emitting diodes (LEDs) compare? Metal Halide lights require a notoriously long warm up period. Some metal halide lamps have long warm-up periods (15-20 minutes) when the light is first turned on or in the event that the power source is interrupted. 1.0.1.1 VIVOSUN 98% Ultrahigh Reflectivity 315W CMH Grow Light: The verdict; 1.0.2 2) Hydroplanet CMH 315W System Fixture: Best durable. Types of the High Intensity Discharge Grow lights Metal Halide Grow lights . Metal Halide vs. They are known to improve the growth rate of the stems and leaves of the plants better than any other grow lights. The primary visual difference between them is that metal halide light is white and the light emitted from a High Pressure Sodium bulb is amber orange. High pressure sodium grow lights produce up to 40% more lumens per watt than metal halide lights, and this then leads to much higher yields when marijuana is flowering. Correlated Color Temperature (read more here). Basically, this just means turning off the red or blue diodes on the grow light. Therefore, when replacing a metal halide light with an LED fixture, you’ll likely need fewer lumens. Before we breakdown the contenders, let’s talk about the current reigning champion. They are known to improve the growth rate of the stems and leaves of the plants better than any other grow lights. Near the end of life, the bulb will begin to exhibit cycling. Diodes are generally made from semi-conductive materials such as silicon or selenium - solid state substances that conduct electricity in some circumstances and not in others (e.g. HPS lights are about twice as efficient in terms of power use as metal halide lights, so in other words, they run cooler and they cost you much less money to run as well. When I first started growing, I made the mistake of … Lighting 101: LED vs Metal Halide & High Pressure Sodium. From here on, I will use the LED fixtures. Metal halide lights are very efficient compared to incandescent lights (75-100 lumens/watt source efficiency). Hybrid lighting systems, consisting of High Pressure Sodium (HPS) and full spectrum Light Emitting Diode (LED) grow lights, can be used together to grow and flower plants – outperforming HPS-only lighting systems. Among the deficiencies in metal halide lighting are the following: Among the minor deficiencies in metal halide lighting are the following: Common applications for metal halide lighting includes large sport facilities like stadiums or hockey rinks as well as high bay lighting for warehouses and large indoor spaces. Foot candle is a measure that describes the amount of light reaching a specified surface area as opposed to the total amount of light coming from a source (luminous flux). If you’re interested in the technical details of how an LED works you can read more about it here. As a result, LED grow lights give off much less heat than HID bulbs. A 900W LED grow light will cover a 4 X 4ft space. That all said the up-front cost of LEDs when compared to metal halide lights are actually fairly close. You can, about the impact of directional lighting by learning about  a measurement called “, advances in LEDs will likely improve their droop qualities, We couldn’t find any objective data on metal halide bulb performance in high temperature situations. LED light costs are high but variable depending on the specifications. at certain voltages, current levels, or light intensities). A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). Where LEDs really shine, however, is in their system efficiency (the amount of light that actually reaches the target area after all losses are accounted for). HID grow lights are significantly cheaper than LED grow lights, however, they may not perform as well. Efficiency losses are greater than LEDs and the degradation time shorter in the case of Metal Halides. Types of the High Intensity Discharge Grow lights Metal Halide Grow lights . Although they cost about the same as LEDs, metal halide bulbs will keep adding expenses over time based on the inefficient way in which they operate and the frequency with which they must be replaced. The up-front costs of an LED lighting project are typically greater than most of the alternatives. For an interesting take on the history of street lighting in the United States read, LEDs are available in a wide range of color temperatures that generally sp, LEDs emit light for 180 degrees. A diode is an electrical device or component with two electrodes (an anode and a cathode) through which electricity flows - characteristically in only one direction (in through the anode and out through the cathode). HID grow lights fall under two category types: the Metal Halide (MH) and High-Pressure Sodium (HPS). These grow lights are commonly used during the growth phase of a plant’s lifecycle. It features highly efficient low frequency ballast with a hammer tone aluminium reflector. Of course this can change in both cases depending on the particular light in question. Metal Halide Grow Lights: These lights are great for early-stage plants as they emit a cool blue shade of the visible spectrum which helps the plants grow in size and generate more leaves and develop more foliage in general. Still, the LED grow light industry has come a long way and design practices are becoming more consistent. Metal Halide vs LED (Lumen Comparison) HPS lights are about twice as efficient in terms of power use as metal halide lights, so in other words, they run cooler and they cost you much less money to run as well. Most values for LED system efficiency fall above 50 lumens/watt. Considering the upside you might think that LED lights are a no-brainer. By far the best thing metal halides have going for them is the high quality light they output. This is a major issue for several reasons: They must be operated for longer periods of time than an LED because they do not switch on and off on demand. Note: Foot Candle ratings are very application specific and vary case by case so relative performance is difficult to generally quantify. A CMH uses a ceramic arc tube similar to those used in HPS grow lights instead of the quartz used in traditional metal halide grow lights. Built in digital timer eliminates the need to buy extra … Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. This can already be seen in the plethora of LED grow light products in the market boasting their comparatively passive operation, which is usually not possible when running a metal halide-bulb. at certain voltages, current levels, or light intensities). It is the most efficient way to grow indoors. LEDs have an extremely long lifespan relative to every other lighting technology (including LPS and fluorescent lights but especially compared to metal halide lights). The modern hobby and commercial cultivator now have the power to dial in spectrums specific to the plant strain they are growing. Photopic vs Scotopic Lumens. If you have any information please contact us. Typical source efficiency ranges 37 and 120 lumens/watt. (a device that converts visible light into electrical current). They lose out to LEDs principally because their system efficiency is much lower (<30 lumens/watt) due to all of the losses associated with omnidirectional light output and the need to redirect it to a desired area. 1 10 Best Ceramic Metal Halide lights Reviews in 2021. For a history of LED lighting read here. Metal Halide lights produce relevant amounts of both IR and UV radiation. Both Metal Halide and High Pressure Sodium bulbs are part of the HID family of bulbs. They reach maximum brightness near instantaneously. LED Grow lights produce very little heat, which for many is an advantage. Unlike HPS grow lights, LEDs are renowned for their longer lifespan: 50,000 to 100,000 hours of constant use. Please find useful links below for the best led grow lights. LED Grow lights are made up of individual diodes that are focused on specific wavelengths of the light. Get all the latest information on LED Grow Lights, Sales and Promotional Offers. Not only are they more efficient than incandescent lights, but they also burn much brighter. However, as technology has evolved, other types of lighting may be a better option for you. There are several reasons for this to include the fact they waste very little energy in the form of infrared radiation (heat), and they emit light directionally (over 180 degrees versus 360 degrees which means there are far fewer losses from the need to redirect or reflect light). Both lights (depending on the specific model and specifications) typically sell for around $10-$30 per luminaire. This means that metal halide bulbs can be very useful for high intensity applications like vehicle headlamps, athletic facility illumination, or photographic lighting. Searching for a CMH light can be … As a result of the operational lifetimes of LEDs and the frequency with which bulbs have to be changed out, LEDs are by far the best on the market in regards to lifetime costs. Metal halide bulbs require regular relamping and ballast replacement in addition to the labor cost to monitor and replace aging or expired lights several times within the typical lifespan of a single LED. LED Notes. ... Or adding certain lights Not led into our grow rooms to complement the LED lights without using lighting that is known for using allot current . Lifespans are variable but typical values range from 25,000 hours to 100,000 hours or more before a lamp or fixture requires replacement. Try our value engineering service. I have purchased my last bulb replacements for the HID fixture. The typical lifespan for a metal halide bulb, by comparison, is 12-30% as long at best (generally between 6,000 and 15,000 hours).
