These merchandise are reviewed in extra depth below, nevertheless you’ll click on on on the hyperlinks above to check out pricing or critiques.
To start out with, what are these lights really often known as? Ceramic Metallic Halide (CMH)? Delicate Emitting Ceramic (LEC)? Or are they Ceramic Discharge Metallic Halide (CDM)?
The fact is that every one these completely completely different names are talking concerning the equivalent Ceramic Metallic Halide (CMH) experience. LEC is certainly a trademarked time interval for a CMH mannequin. With a view to avoid confusion, I’m going to be using CMH on this text, which is the most common time interval.
Ceramic Metallic Halide develop lights are principally a variation of MH develop lights with a little bit of of HPS added into the mix. A CMH makes use of a ceramic arc tube very like these utilized in HPS develop lights instead of the quartz utilized in typical metal halide develop lights.
The ceramic arc tubes perform at elevated pressures than quartz glass tubes, which allows producers to make further precise variations on the spectrum than with earlier utilized sciences.
The Advantages of CMH Develop Lights
There’s a objective people are wanting into CMH develop lights, and it’s the huge itemizing of advantages when as compared with practically every completely different develop mild alternative.
Balanced spectrum
Not solely do you get a further balanced spectrum that hits practically every sweet spot in your crops nevertheless they’re moreover larger at turning your electrical vitality into usable mild.
By comparability, HPS and MH lights waste a complete lot of energy producing mild at ranges that are not successfully utilized by crops. Which signifies that CMH are further PAR atmosphere pleasant than each HPS or MH, making them a higher single mild decision.
Shade Rendering Index
Moreover they’ve a further pure CRI (Shade Rendering Index). CRI describes how the color of a light-weight provide modifications how an object appears to the human eyes and the best way correctly refined variations in shade shades are revealed. The higher the CRI, the additional actual trying points look. CMH develop lights are often rated between 80 to 96 CRI, by comparability, the photo voltaic is rated at 100 CRI. Which signifies that CMH develop lights will assist you to see the true shade of your crops with out making your develop room look yellow, blue or purple.
Ultraviolet Radiation
CMH develop lights current UV (extraordinarily violet) radiation, which although being exterior of our differ of imaginative and prescient is helpful (at certain ranges and intensities) to plant improvement and enchancment. They produce UV-A, UV-B and UV-C Delicate, nevertheless UV-C is generally very harmful to human eyes. So most top of the range producers use a glass filter to dam the UV-C output whereas leaving UV-A and UV-B output intact.
Bear in mind: All HID bulbs emit some amount of UV radiation. The amount may differ and they also’re sometimes shielded. Nonetheless consider not to check out or work spherical a bulb with a broken outer glass jacket because of UV radiation burns, and this hurt is cumulative.
Longer Lasting
Ceramic arc tubes are further proof in opposition to breakdown, so that they last tons longer than MH and HPS bulbs. In reality, CMH develop lights are inclined to last over 24,000 hours whereas conserving a minimal of 80% of their genuine depth on the 20,000-hour mark. This overshadows the frequent 10,000-hour substitute rule for HPS & MH bulbs.
In summary:
- Balanced spectrum
- Increased PAR effectivity than MH or HPS
- Extreme CRI for seen enchantment
- UV supplementation
- Lower heat output watt per watt
- Final greater than completely different HID develop lights
The Disadvantages of CMH Develop Lights
Weaker in Flowering Than HPS
With reference to flowering crops, HPS lights are nonetheless the “HID King.” It’s as a result of HPS develop lights output further mild inside the purple spectrum than CMH lights. Even nonetheless, the controversy rages on. For individuals who consider CMH to HPS on a watt by watt basis, CMH lights do have a further balanced PAR spectrum than HPS lights. And evaluation stays to be being carried out to find out if the extra benefit of a higher spectrum improves the final crop even with the diminished harvest.
Heat Output
CMH develop lights usually output a complete lot of mild inside the infrared part of the spectrum (over 700 nm) which makes them output varied heat. Although it nonetheless a lot much less heat than completely different 400w HID bulbs, it’s noticeable even once they’re consuming a lower wattage.
Upfront Worth
One different downside is the preliminary value. Usually a high quality 400w MH or HPS develop mild bundle (along with ballast, bulb and reflector) costs spherical $200, by comparability, the preliminary funding for a complete 315w CMH bundle hovers spherical $500, which is a fairly hefty preliminary funding. Nonetheless, in the long run CMH will nonetheless stop further energy.
In summary:
- Not the absolute best for flowering crops
- Extreme heat output
- Extreme preliminary funding
The CMH Develop Delicate Spectrum
With reference to regular rising, CMH provide basically essentially the most full PAR spectrum in any HID bulb accessible on the market. There may be completely different further “focused” develop lights, however once we’re going for basically essentially the most complete balanced single develop mild HID decision CMH sits on the prime…and actually comfortably too.
Proper right here’s a comparability between the 3100K and the 4000K CMH spectrums, along with HPS spectrum:
3100K Spectral Learning
4200K Spectral Learning
Spectral Learning of the EYE Hortilux Great HPS
In order that you acknowledge, the EYE Hortilux Great HPS is my resolve for the most effective HPS bulb. So you’ll see the excellence in output proper right here.
For individuals who remember the fact that PAR is mild inside the differ between 400 to 700 nanometers, and is the exact usable mild by crops. You may uncover that neither MH lamps, nor HPS lamps provide a further full PAR spectrum in a single develop mild. Usually, MH bulbs are sometimes heavy on the blue, and HPS on the purple side, which is why many growers who want the right cowl combine every utilized sciences.
CMH ought to be blended with HPS for an added enhance on the purple spectrum which benefits flowering crops loads.
The specifics of CMH ballasts are a little bit of bit troublesome. It is extraordinarily actually useful that you just simply purchase an entire CMH bundle instead of attempting to retrofit a CMH bulb into your outdated ballast.
Usually CMH do not run on most digital ballasts because of terribly extreme frequency these ballasts output. Regardless, there are some extreme end digital ballasts that will run CMH develop lights with none points on account of their microprocessors.
To avoid any points and confusion, CMH producers insist that you just simply buy a CMH develop mild bundle, this comes with the bulb, the ballasts and a reflector all linked collectively for ease of use and arrange.
A benefit of the square-wave experience ballasts required to run them, is that you just simply acquired’t should handle the electromagnetic interference (EMI) factors many growers experience with digital ballasts.
Hanging & Positioning a CMH Develop Delicate
That’s the PAR map of a Photo voltaic System LEC 315 develop mild. It makes use of a Phillips 315W/930 (3100K spectrum).
These PAR measurements had been carried out at a peak of two ft over the quilt which is the sweet spot for a 3 by 3 ft develop house. We don’t truly advocate them for a 4 by 4 because of the outer edges aren’t going to be receiving loads mild, nevertheless in the end that’s the growers title.
Ceramic Metallic Halide lamps are sometimes rated for widespread positioning, which signifies that they’re usually positioned vertically along with horizontally, so be at liberty to fiddle with the positioning to hunt out the most effective configuration in your develop house.
Summary:
- On the very least 2 ft over the quilt to avoid scorching spots and provide an excellent unfold
- 315w actually useful for a 3×3 ft develop house as a lot as a 4×4
- Will likely be positioned in anyplace with out damaging the bulb
CMH vs. MH
To start out with, Ceramic Metallic Halide and Metallic Halide bulbs often usually are not the equivalent issue.
Even once they share a complete lot of the equivalent experience they’ve fundamental variations in the best way wherein they’re constructed and the best way they perform. You can’t merely use your new CMH bulb in your outdated MH ballast. Attempting to take motion might be very dangerous.
For comparability capabilities, the one downside I can take into account CMH over MH is the preliminary value. With that talked about we’ve made it clear that CMH has a considerably higher complete spectrum than MH, significantly with that purple enhance at every 3100k and 4000k spectrums. CMH moreover run cooler, and produce far more PAR mild in contrast watt per watt.
In all probability essentially the most noticeable degree is degradation time. Regular MH bulbs have a lifetime of spherical 10,000 Hours. Which is decrease than 50% of the 24,000 Hours that CMH are rated for.
MH Elements
CMH Elements
- Effectivity
- Significantly improved spectrum with a correctly needed enhance inside the reds over MH
- Prevents Stretching
- Significantly longer life time
CMH vs. HPS
As beforehand talked about, HPS develop lights are nonetheless the king of flowering crops. And that’s simply concerning the one issue they’ve over CMH.
HPS develop lights current most of their PAR mild as purple mild, which is strictly what flowering and fruiting crops need at that improvement half. Nonetheless CMH develop lights nonetheless current a further balanced PAR spectrum that doesn’t encourage stretching identical to the RED mild from the HPS does, further PAR mild per watt and an complete cooler operation.
My suggestion for anyone working Flowering crops is to utilize CMH as base lighting and use HPS as an added purple mild complement to encourage the biggest and highest prime quality yields. One different degree is that ordinary HPS have to be modified every 9,000 Hours resulting from their necessary degradation over time.
HPS Elements
- Biggest flowering spectrum accessible
- Further fairly priced
CMH Elements
- Effectivity
- Balanced Spectrum for the entire cycle
- Prevents Stretching
- Over twice the usable life time
CMH vs. LED
On this case all of it’s going to rely upon what we’re evaluating in the direction of. Horticultural LED lights have certain advantages over HID lights in that they’re further energy atmosphere pleasant, produce very low heat and may very well be positioned very close to the quilt with out burning the crops.
Nonetheless as of correct now LEDs are sometimes not likely useful because of they “underperform” on account of producers mislabeling their merchandise with ridiculous claims. Even though, there are a whole lot of upcoming LED develop mild producers who current factual descriptions of their merchandise.
For instance, there’s the SPYDR by FLUENCE which outputs a further evenly distributed and targeted PAR spectrum than a CMH whereas moreover masking a 4 by 4 ft cowl with an equivalent energy consumption. The draw again is that this LED setup could also be very expensive. It costs spherical $900, and at that value degree a CMH setup is definitely a further fairly priced completely different till low heat circumstances and closeness to the quilt are an absolute necessity.
The CMH vs. LED battle stays to be occurring, there are LED utilized sciences like SMDs and COBs which seem very promising for indoor and outdoors growers looking out for cooler and additional atmosphere pleasant lighting. Solely time will inform who comes on prime.
LED Elements:
- Can merely purpose explicit PAR ranges
- Rather a lot lower heat manufacturing
- For for much longer working time
- Not many selections (nonetheless in enchancment)
CMH Elements:
- Much more fairly priced
- Lower usable life time
What Should You Buy?
As a traditional rule, it’s best to buy a complete CMH system because of factors it is potential you will face in attempting to retrofit a CMH bulb to an outdated ballast of yours. For individuals who’ve already decided it’s essential to develop with ceramic metal halide experience, then you definitely definately’ve gotten over the reality that they’re a bit costlier than regular HID selections.
Beneath, I’ve chosen the most effective strategies, bulbs, and ballasts out there available on the market for CMH growers, so no matter which route you are taking, I’ve obtained you coated.
Biggest CMH Develop Delicate Strategies
Biggest Normal: Photo voltaic System LEC 315w CMH
As I’ve actually useful, it’s sometimes best to easily get a CMH system instead of piecing it collectively your self, largely on account of compatibility factors with ballasts.
The Photo voltaic System LEC comes collectively together with your different of 3100K or 4200K bulbs, and 120v or 240v. It contains a acceptable sq. wave digital ballast, so that you just acquired’t have any funky factors attempting to match the bulb as a lot as an outdated ballast.
All in all, you’ve obtained a hooded reflector, ballast, and bulb for a value that’s exhausting to beat. That’s by far your best option for a complete CMH system.

Biggest Price: Nanolux 315w CMH Fixture
The Nanolux is one different sensible choice while you’re attempting to avoid wasting a little bit of bit of cash. The ballast is prime mounted, so all of the items hangs above your crops. This might presumably be a bit scary, so make sure you’ve got an excellent develop tent that’s capable of holding up all that weight.
Sadly, the Nanolux does NOT embody a bulb, which contributes to its decrease price. Nonetheless, in case you’ve got your eye set on a specific CMH bulb, then the additional customization may be a revenue to you.
All in all, it’s a good different in case you want to save about $100 (after purchase of a bulb).

Biggest CMH Develop Delicate Bulbs
Biggest Normal: Philips Mastercolor CDM-TP Elite 315w
Philips was certainly one of many first companies to develop and manufacture ceramic metal halide bulbs, so it’s no shock that their bulbs are the most effective in school. This isn’t merely personal opinion — it’s objectively the most effective.
What I suggest by that’s that the Philips bulb, whether or not or not in 3100K or 4200K, has the very best PAR measurements of any CMH bulb at current out there available on the market. They do about 8% larger than the second best bulb.
The Philips Mastercolor is available on the market in 3100K and 4200K.
Biggest Price: Ushio HiLux Gro 315w CMH
For individuals who’re looking out for another option along with the Philips, the Ushio HiLux Gro is a powerful different. Ushio is well-known for his or her prime quality bulbs and earned most of my “best value” picks in my best HPS bulb roundup.
The Ushio HiLux Gro is available on the market in 3100K and 4200K.
Biggest CMH Ballasts
Phantom II CMH Digital Ballast
For individuals who fully have to assemble your particular person CMH system instead of buying a bundle, the Phantom II CMH digital ballast is an effective alternative. I might nonetheless stress that you just simply buy a bundle instead, because of the price of this ballast plus the alternative gear you need to get your CMH system up and working will potential value further than merely purchasing for a system outright.
Nonetheless, it is potential you will already have a bulb and reflector and easily desire a ballast. For these of you on this state of affairs, the Phantom II is a square-wave ballast from Hydrofarm that is your best option.
