This makes them ideal for growing from seed to flower with the one bulb. Leaning towards transitioning to LEDs but.... buddy is saying that LEDs arent that much more efficient than CMH and CMH has a better spectrum than LED. Gone are the days of the ‘Blurple’ LED grow light (blue and red diodes only). Sure, there are a few downsides to using CMH bulbs, but this is the case for every type of bulb. LED vs LEC/CMH lighting watt for watt So I'm looking to upgrade and I've been looking at building a DIY LED setup for my tent. Our horticultural quality CMH fixtures are designed for the most efficient CMH (Ceramic Metal Halide) lamp in the market. Unlike LEDs they do contain fragile filaments. Ceramic Metal Halide is becoming popular and is praised for its performance during the vegetative stage of plant growth well. Great question, Robert! by Shane Torpey | Nov 4, 2020 | Uncategorised | 0 comments. Ceramic Metal Halide; Ceramic HPS; Double Ended Ceramic HPS; Ceramic HPS™ Lamp Ballast Kit; T5 Fluorescent. Light Emitting Ceramic (LEC) grow light – “LEC” is a brand name (trademark) for a model of grow light that uses ceramic metal halide technology. A CMH lamp has a different emitter than a normal metal halide lamp, which is built of Quartz. This is ideal for indoor growers who are generally limited for space. As previously mentioned, although ceramic metal halide bulbs are derived from metal halide, they are very different and they can not be run in the same system. LEDioc® 30W and 50W FLX HID to LED Retrofit; LEDioc ® 30W and 50W FLX HID to LED Retrofit for Wireless Controls; EYE Lighting LEDioc ® Custom Engineered Solutions; HID Lamps. The other main consideration is heat output of the lighting system. Topic. A recent addition to the market is Ceramic Metal Halide (CMH) bulbs. 3. The LED fixture (Lighting Sciences Group) uses optics to achieve a narrow distribution, with the majority of the photons falling in a concentrated pattern directly below the fixture. Inside a CMH there is a ceramic component. LEDioc® 30W and 50W FLX HID to LED Retrofit; LEDioc ® 30W and 50W FLX HID to LED Retrofit for Wireless Controls; EYE Lighting LEDioc ® Custom Engineered Solutions; HID Lamps. Growers House 80,628 views. Lets take a look at a Metal Halide Lamp. PowerVEG Family; Veg Formula; Flower Formula; Start-to-Finish Formula; Metal Halide. Ceramic Metal Halide lights get good results in the cannabis flowering stage, much better than a standard Metal Halide does. To achieve the lower operating temperature in HID lamps made with quartz or PCA, a combination of gases must be used that don’t necessarily produce the optimal light spectrum for photosynthesis . HID to LED Retrofit Lamps. It is now difficult to justify the description of HID lights as cheap if you are taking into account running costs. The most common bulb sizes of each type are as follows: Metal Halide: 400W, 600W, 1,000W. These are also HID grow lights, but they use one or two special CMH bulbs, usually 315 watts each. Generally for a 600W MH or HPS system with digital ballast and a quality reflector you will need to spend about $200 to $300. Ok, a couple of notes. They are more expensive per watt but they have a good spectrum (about 11% blue) and a higher efficiency than HPS in most cases. Metal halide lights tend to be considered great full spectrum grow lights, and thy are great for the vegetative state, as they usually produce really lush and thick vegetation which is great for getting weed plants ready for the flowering stage. You’ll see others like PPF, and PPFD, and others, but those refer to the amount of total light and light intensity, but not specifically to spectrum. There are a lot of nuanced differences between the two light systems, and I’m going over as much as I can in this quick overview. The main difference is it uses a ceramic arc tube like an HPS grow light, which makes it more electrically efficient. Ceramic Metal Halide CMH 315W Lamp Comparison Test Data & Review - Duration: 11:17. Standard metal halide bulbs use a quartz arc tube whereas the CMH systems use ceramic, which lets the bulb get hotter to give you that perfect spectrum of light CMH's give off. Prism Lighting Science Ceramic Metal Halide: The verdict. CMH grow lights produce a full spectrum of light. Light Spectrum in CMH vs LED Grow Lights CMH Grow Lights. Best Grow Room Conditions For Maximium Yield. Even if they share a lot of the same technology they have fundamental differences in the way they’re constructed and how they operate. LED vs HID Grow Lights | The Final Chilli Battle - Duration: 2:40. Ceramic Metal Halide is becoming popular and is praised for its performance during the vegetative stage of plant growth well. They are more expensive per watt but they have a good spectrum (about 11% blue) and a higher efficiency than HPS in most cases. The LED systems emit about 40% of its consumed power as heat into the grow tent and emit almost radiated heat as the led surface temperatures are low. CHM (Ceramic Metal Halide) lighting grows healthier plants when compared to those grown by LED lighting. However, when the running costs are taken into account over three years the more efficient CMH is the most cost efficiency HID option. Something that is cool about metal halide bulbs is that they can often be customized and changed. Lumens Efficiency. If the proportion of blue exceeds about 6% than the plants will have short internodal distances and develop short and dense growth in the VEG stage. GE's Protected Ceramic Metal Halide and Quartz MPR Lamps are equipped with an EX39 exclusionary base. HID will emit about 75% of its consumed power in heat and HID bulbs emit a lot of radiated hear in the for of infra red as the bulbs glow at above 320 DegC or 600 DegF. The ceramic discharge metal-halide (CDM) lamp, often referred to as Ceramic Metal Halide lamp (CMH) is a source of light that is a type of metal-halide lamp which is 10-20% more efficient than the traditional quartz metal halide and produces a superior color rendition (80-96 CRI).. LED Notes. First, they have a wider spectrum than other HID lamps - a result of the near-perfect, unique combination of salts, halide's and gases used in the arc tube. Plants typically absorb a specific portion of the light spectrum called Photosynthetic Active Radiation, or PAR for short. Alternatively you could upgrade your ballast and bulbs to CMH and you will get payback within a few years compared to running MH and HPS. Conversely, the Cycloptics ceramic metal halide fixture is designed for even light Metal halide grow lamps are slightly better at vegging than CMH bulbs, but the difference is minimal. HID to LED Retrofit Lamps. CMH metal halide grow lights are made with an arc tube constructed of a ceramic composite instead of quartz or PCA. Most LED grow lights now emit a neutral white spectrum which is very similar in output to CMH and is optimised for ideal plant development and high yield. However, due to the low percentage of blue in the spectrum the plants will also stretch excessively. There is a sub-category of Metal Halides called Ceramic Metal Halide (CMH) grow lights. HID to LED Retrofit Lamps. For those who have yet to discover the beauty of the LED, LED bulbs are “Light Emitting Diodes,” where electricity flows through two electrodes ­- an anode and a cathode). What Ceramic Metal Halide brings to the table is their superior light quality compared to other HID lamps, which is due to a few factors. Cree LMH2 modules enable true 50 watt and 70 watt ceramic metal halide LED replacements and support an expansive range of lighting applications, including downlights, wall sconces, pendants, flush-mounted, spot, track and ceiling fan lights. However, the LED grower will use less power for cooling, but that savings depends on other factors in the grow space. Ceramic Metal Halide (CMH) Ceramic metal Halide bulbs are improved versions of HID lights which were designed and developed to offer a more improved efficiency and blended spectral output. Blue regulates internodal distance (the distance between branches). First, we’ll take a look at the average stats of a typical 400-watt metal halide … Table of Contents. CHM lights provide plants with very high-quality light. 2 years ago. Presently, if you opt to grow indoors, sufficient lighting is essential to stimulate the process of photosynthesis.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). They have a very high CRI value – the light produced is very similar to sunlight. Manufacturers of both LEDs and CMH grow lights claim to produce the best plants, but which really works best for your situation? 1. LEDs are available in a wide range of color temperatures that generally sp an from 2200K-6000K (ranging from “warm” yellow to light or “cool” blue).. Metal halide lamps generate a very cool white light. These lights put out an impressive spectrum of light that replicates natural sunlight better than any light I … However, the term “LEC” is starting to become interchangeable with the term Ceramic Metal Halide (CMH) since they’re both referring to … Read Also; LED Vs HPS Grow lights . They produce good results and can be used with larger plants that less intense lights like fluorescents. Super HPS; Double Ended HPS; Dual Arc; Ceramic. But unlike HPS, CMH offers the full-color spectrum and mimics sunlight so that your plants don’t miss out on anything. The third important factor to think about when it comes to selecting a metal halide bulb also regards the arc tubes. Light Emitting Ceramic (LEC) grow light – “LEC” is a brand name (trademark) for a model of grow light that uses ceramic metal halide technology. The 315W SE and 630W SE (dual 315W lamp) are available as 3000K for flowering, or 4200K for vegetative or supplemental use. LED 700-ES; LED 450-EVS; LED 240-R; HPS. LED 700-ES; LED 450-EVS; LED 240-R; HPS. Despite the low cost, the grow light performs optimally. An LED ran cooler than CMH's by at least 2°F, and overall 10°F lower temperature from a higher-powered LED. The number is generally represented as PAR Watts, which simply refers to the amount of energy in the PAR portion of the light spectrum, getting to the meter each second.
