It would be nice to see an update including the Hortilux CMH, I would like to see how they stack up to the Phillips bulb.
waaay out of date ....
@@SweetManCannabizz Just because they are "out of date" doesnt mean they arent still one of the best ways to grow. I would have to run an electric heater in order to run LED so all the extra efficiency is for nothing. You can pick up used CMH fixtures for pennies on the dollar these days and for people just starting out that is an excellent option. Thats why we are still out here learning what bulb is best. I have the exact same question, how does the Hortilux compare?
They all seem decent the hortiux Is a horticulture Bulb tho not really a grow cmh, so my plant will hang out under it and stay healthy for longer periods where other bulbs will make the plant sick. I can't flower till spring so im using it to keep it warm and as a light source. I wouldn't recommend it as a grow bulb. If your pumping shit out you don't really need it, if you wanna plant to hang out it's great. They all similar but Philips didn't burn as long as advertised. The hortilux Is also larger designed for the bigger units no one wants to use and takes advantage of the units reflector. It would be really good for a bonsai tree if we could get seeds that would actually germinate.
@@eagle94haslandedyour just not going to get the UVs and IR from an LED without suppliment bars. I use leds in veg and CMH in flower
@@shotnva777 yeah I won’t grow again till next winter but I’ll do the same. Led veg and CMH flower.
Excellent job conducting such a detailed and scientific research into this topic! Thank you!
I am definitely shopping at your shop next time I need a big grow purchase, such a great indetail test, for damn near everything from you guys. That alone is worth shopping here, even if I had to spend an extra buck or two

Growers House what would be a good light to canopy distance in a 5 ft 7 inch high grow tent? It is 3x3x5'7
Thanks for posting this! 👍
Great review.. Im curious if you have done any testing with the CMH bulbs available with the E39 mogul base?
looking back at your DE hps test, it was only carried out in a 3x3 area where as the Lec was carried out in a 5x5 area, even though the 1000w DE has a foot print of 5x5. If the test was done in a reflective area would that mean you can compare the sum of all footprint areas of both theese lamps even though the footprint size is different?
Great review. With all the new digital CMH ballasts available, Phantom II, Galaxy, Prism, Nanolux ect., it would be cool to see a side by side of the ballast output for each unit on the same CMH lamp. I'm in the market, but every time I decide on a CMH ballast, another company jumps in the game.
That would be a great test to do. I'll throw that in the queue and we'll see what happens ;)
Sounds sketchy. Why so low?
that is about average actually. there is a shop near me selling 315 cmh setups for 250 right now
Jared Labriola my bad I was thinking 630. I was like wtf hahah
Appreciate the test and review you guys do. Thanks. More CMH and LED info (par tests, ppfd, etc) would be awesome.
Thank for this video brother, although I didn't understand too much about what u said for cmh ..
Nice epic stuff here man my buddy pulled a crop off with outstanding results turns out he had cmh so im betting it was that because he is a new grower
for example, im thinking of using 3x lec 315w phillips 3100k, which according to you results should give me a total sum of around 30,000 par? when comparing to a DE hps i can only see that in a 3x3 area the total sum is 18,000 for the phillips green power? thanks
@Growers House Hydroponics Great vid! I'd also be curious to see how the Dimlux, another digital CMH ballast manufacturer which boasts 1.9umol/watt would stack against the competition.
I use the 315 sun system LEC and I have grown 4 crops so far on a 5x5 scrog and I get awesome results with 2 lamps. BIG Rock hard dense nugs..but this is strain dependent. GG#4 performed great as did Legend Of Zelda,and Crocketts Dawg,and so did Sour Sunset.
Mike Somewhere just ordered my 315 to pair with my led lights in a 4x4
have u tested the Philips 315w 930 do u have video or review compared
Can you test the hortilux 315 ?
im ordering tomorrow...so for best of both worlds..use a 4200 for veg and 3100 for bloom?
I was wondering if you have any old lamps? say 10,000 hours. i'm curious to measure the spectrum of them to see if they shift with age.
Got stupid question can the 315 from digital greenhouse run a Philips bulb. Ivd heard most CMH brand lights make it so their light will only run at its optimum level with that brand of CMH lighting fixture.
Thanks!!! Big help 4 sure
are all of your lamp tests done in a refective area?
Thank you very much for this info, well delivered too.
what is the best ballast to go with the philips 3100 k ? thx!
Iv heard that eye hortiluc cmh bulbs blow everything else out the water from everyone who's tried it. Love to see some tests comparing that one with Philip's and vivosun and other top line and also budget lights compared
I got two of these 4100k Phillips bulbs (huge) 2 ballasts and 2 15ft e39/mogul cord to the ballast for 60. Where I’m from when your done with growing the equipment becomes similar to old unused excersize equipment. People just want it gone. I can get a few more if anyone needs them
Also. What’s a good reflector for them? Just a reflector.
How do these compare to the full spectrum led lights? I have 1 240watt full spectrum led I’m going to use as supplemental lighting. I can grow cannabis legally but I love cacti 🌵 so that’s whats under my lights.
Is that Phillips 3100 would that be good for veg all the way through flour or would I need to change bulbs when I flip it to flower and if so what's a good flowering bulb Phillips I suppose but need the number thanks a lot your videos good too
You can veg really well with 3100k
i have a 630w cmh fixture in a 4x4 and it kicks ass. can i but one of each bulb in there and if so spectrum would that be best for? great vid!
Realistically, having both the 3100 and 4200 bulbs in one fixture would be great for both vegetative and flowering phases of growth. You'll have a very nice and well rounded spectrum with that setup. Seeing that the 3100 bulb has slightly more output than the 4200, you could also think about throwing another 3100 when you go into flower or maybe just the last 4 weeks of flower. Other than that, you have an awesome setup!
Growers House Hydroponics the hood for the 630w cmh is massive in a 4x4. plus the air filter and fans. If anything i can add a small led. I'm running auto drip into coco with house&garden coco nutes. clusterfunk cookies and critical mass 😉👍
Hi, may I use the information provided here in my blog? Picked parts would be translated in Finnish and I can add your video/blog as one of the references if you like.
Yes, you can Tom. There may be some other resources we can offer you. Please email nate@growershouse.com for more info.
I have original 400 watt philips Ceramic bulbs. My neighbor bought a case before Philips stop manufacturing the 400 watt in 2005. They look identical to the 315 Watt bulbs. Do you think I can run them on a 400 watt hps ballast?
TAZ Tactical nope!
TAZ Tactical You can run them on a magnetic HPS ballast. That's how I first tried the tech myself and was impressed. Recently got a 630w CMH-DE low frequency square wave ballast with a remote and dimmer/booster and a digital read out from Ceramic Solutions out of N. California. Growers Choice are very popular but are using high frequency ballasts now. Which work, but lamps diminish 3-4 times faster. I bought a Hydro Crunch CMH-DE ballast and lamp and had to return because of lamp flickering. The Ceramic Solutions ballast and lamp (I use in an AC/DE hood from Sun Supply) has been excellent so far. Great guys! I started with a $20 used HPS magnetic ballast and bought the 400watt Phillips CMH (Retro white? Master color?) and was very impressed. Those older Phillips bulbs are still in demand, so if you didn't use them, they'll sell! Good luck!
Wow that Sun System CMH has very bad light uniformity. That hot spot in the center is gnarly. The GreenBeams CMH reflector has the most uniform light distribution I have seen. Either way, good comparison vid for the tools on hand.
The adjust a wing with a super spreader is the best, when using a DE cmh or hps that is
I just bought 3 cmh315's, how far apart should I hang them.?
spread even in a 4' by 8' space
If you have a 4' x 8' space, I'd recommend evenly spreading them out over that 4' x 8', and then kicking the two outer fixtures an extra 6 inches toward the perimeter of your 4' x 8' area. You'll want to do this to even out the intensity of your canopy. The cross lighting from fixtures being next to each other has an additive effect that isn't present on the opposite side of the outer fixtures, if you get what we're saying.
I'm getting a 3x3x6 tent soon. I'm debating getting a 600w LED or some sort of CMh 315k Phillips setup. I heard the CMf is better for the budding stages, is that true? I've been told the CMh will be half as much electricity per month but its also over twice the price so it wont end up saying me money until like 3 years from now. Marijuana just got legalized in MA so please guys any input would help. CMf or LED ??????
Trevor Speck I would do CMH. I got a fixture for $240 for a 315 watt. It's in a 3x3 with carbon filter. I also have a blackdog phyto-2 200 in another 3x3. It was $664. It's doing really good and it's only 210 watts but you could get two 3x3's and two CMH light set ups for around $600. I spent about $1500 on my two tents mostly due to the blackdog. But you have to remember. 210 watts for a 3x3, 5 year warranty and no bulb changing. In 5 years I'm sure I will have to change the bulb on the cmh at least a couple times and they are $100 bulbs. So right there add another $200 to $300 on top of the original light purchase for around a 5 year period but none for blackdog.
I couldn't go back to using any of these light's over led lighting to much heat and its just not worth it for my situation
What would be a good setup for a 5x5? Mid to low tier
A hellion 630w de cmh in the adjust a wing reflector with super spreader. A 600/750w de hellion hps would be even better though. Both amazing beasts of lights. Led’s are over rated, they don’t get fckall penetration of a canopy, those two lights do.
nate do a review on the growers choice 630 de cmh
3100 or 4k
We just happen to be running that test as we speak!
did you ever do a test of the DE CMH lamp fixtures?
is there 400w CMH on the market or it only goes to 630w ? thanks!
Htg supply has a 400w cmh fixture
in the heat category. ..a 315.is equal to what hps mh bulb.?
DAZE_ 09 air cooled 600
Like ectoplasm?
Im sold what glasses do i get though? halp
As for glasses, either one of these will work great with CMH lamps:

😎👌🏼
How many plants can I grow with 1 or 2 of these
We would usually recommend 2-4 plants per 315w CMH lamp.
You can veg a 6x6 open room with the philips CMH with just 315 watts. You may get some stretch but I've done 2 in a 12x12 room, full.
For bloom, you should use 1 per 4x4 closed tent, as beyond that, you will have less light in the ends of the tent. The bulb is still good compared to newage 2021 LED, as you have a ton of UV which increases resin.
@@dertythegrower Man is a legend these things are pretty strong the higher quality type like GC i got anyways. I did get a cheaper vivosun light and bulbmaybe its the bulb buts its like half the lux as the growers choice bulb and light. Guess need a try another brand bulb in that vivosun fixture.
why cant we see that the 3k is more intense than the 4k.. ? otherwise why do so many recommend the 3k over the 4k when the 4k looks so much more intense?
Looks intense because it has more light that we can see and less red which is plants favorite. 3500k is ideal. I ordered 10 20w cobs to add in grow box
The only difference is the resistor , the gas is the same, I got an osram powerball hci - tt / 830/ 3000k, mh with ceramic resistor, but with E40 connection, nowaday we can find ceramic hps, but in both cases the only difference is the resistor, made of ceramic, e40 and not g12....also the philips master son - t pia plus has the resistor made of ceramic...ballast is the important thing, I mean the ballast to hid and cdm like the electronic ballast of low frequency primalvision hid /cdm by philips.
sweet nose ring broham
Haha, this music is from the game Bit City??
Do you have an e mail addrese pal
Obviously the Philips will be best. It's being used with a Philips ballast, designed to be used for that bulb
phillips wins then?
In both the 3100k and 4200k spectral variants the Philps 315w lamps performed best. From these objective test results, we recommend the Philips lamps for any growers out there.
dave oneil
And what about UV..??? Philips is not the best on that point..
If you touch your gloves with your skin you're kinda defeating the purpose of wearing a glove brah
Your hand moisture oils is what can build up much faster than your face, and break a bulb as it expands the glass to breaking point (some companies claim). It isn't about germs on this case, but the hand oil
This bulb is the doggy's nuts aka plasma killer
Last time I saw something with a piercing in the nose, it was a cow.
Uv so not safe to work under for eyes n skin
Damien Bell you should ALWAYS wear safety gear but still lower than the sun outdoors.
Hydrofarm sucks, bought two and they both had the same problem! Never again.
You have something in your nose
Cocaine!
