Discontinued a few years ago as was a similar 400w model. They were actually conversion lamps for commercial HPS fixtures. They were unique in that they were protected lamps, open fixture rated. GE makes similar conversion lamps but they are *not* open fixture rated nor are the EYE conversion lamps.

thank you brother.
that's a shame for sure.
that must be be why I saw a used one on eBay.
I only have an open fixture for this application.
I guess i'll have to revert to plain old HPS.
Funny - but one of the main reasons for converting was to take better photographs, but I haven't been getting results w/smart phone and CMH.
best regards

So as a CMH/CDM/LEC only person, I thought adding some side lighting to this 32"x32"x63" tent would be fun. The main light is a Philips Agro 315w driven by a Sunplix and mounted in a Gavita reflector replacement insert that I DIY'd.
The side light is a MC70T6/U/G12/930 being driven by a Hatch ballast. The reflector is a cut out from an old PL Lighting Reflector. Just hacked it up with the Dremel really fast.

Hi guys
It may,be a dumb question but can a CMH ballast run a HPS globe. I know it cant be the other way round but i see on a local site theres an all in one unit that says it can run Hps also. If it is possible, what wattage HPS globe would one use on a 315w CMH ballast. I know the cmh bulb itself is great but for the latter half of flower I would like to give it Hps, and switch back to cmh for the final week or so to give her some UV

I can't help you with the HPS on CMH ballast but maybe the one you are mentioning has a switch to alternate? As far as swapping lights during the grow cycle, personally I would grow the plant with HPS until the final 2-3 weeks then swap to CMH.
I want to replace my current three 1kw lights over a 4x8 table (2 hps, 1mh) with cmh for all of the obvious reasons. How many in which configuration would be optimal? Initially I reasoned four but perhaps that's only adequate. Would six (thinking 3 dual 630) be too much? Certainly wouldn't be too much electricity.
I'm handy, but don't want to reinvent the wheel either. Looking for the absolute best in lighting and a lower electric bill.

So is a 3x3 footprint not solid with a 315w cmh? I plan on buying 2 315w units and building a 3x6 room for them but if they cover a 2.5 x 2.5 ft area better (roughly 50w per square ft) then I will be changing room dimensions unless a 3x6 room with a 2.5 x 5 footprint is ok?
I used 1 each over 4x4 trays with good results.
Which would be warmer: 2' below an air cooled 1000w hps or 2' below an open dual 315w cmh?
I want to switch, but I've "upgraded" things in the past and it's not always all it's cracked up to be. I don't want to buy new lights only to find they burn my plants as I have limited headroom. One of best aspects of air cooled hoods is how close they can get without burning.

I picked up a 315 the other day. Kind of as a replacement for an old el cheapo 400 HPS with a ballast that went, kind of for a similar 400 MH that needed a new bulb.
I originally thought about getting a 600HPS system, I don't run venting now, but I do have a squirrelcage fan I could set up. Still, wasn't really looking forward to a higher electric bill.
We'll see how it goes. Definitely impressed by how cool the light is. I keep checking on it because it's crazy close to one plant. No ill results yet, but I keep hoisting the light up more just in case. Eventually I'll remove the table the plants are on and move them to the floor.

Thanks!
I wondered about that, looked to me like I was getting wider dispersal of light when I raised it a bit last night.
Probably time for me to move the table I have the plants on and rejigger my homemade tent (cut panda film to fit the table, will need to cut new pieces to reach the floor).

Just got my self a 945w CDM/CMH full fixture light kit from root 2 success hydro. They said they were new in and you need a 945w ballast the right frequency which is what I bought. Has anyone got any experience with these?

Hi all,
I’m looking for a new CMH and ballast to replace my old Philips 250w CMH (runs off HPS ballast). Grow area is 70cm x 50cm. Height from top of pots to bulb is 95cm. Reflector is Adjust-a-Wings small. The 250w CMH was used to good effect in a space just a little larger than this.
Would a Philips 210w CDM be my best bet, or would a Philips 150w CDM do the trick?
I grow equatorials with very thin leaves, so they are pretty light hungry but I’m not sure how powerful the new Philips CMH are compared with the old.

Do they make a 630cmh with 2 bulbs pointing down vertical? I just built a 4x4 grow room and im considering a 630 but only finding two horizontal bulbs or a double end single 630 cmh bulb.
Also why is the ballasts connected to the reflector? Wouldn't that create more heat problems? Can I get a verticle bulb 630 cmh with a ballast I can hook up outside the room?

Several manufacturers offer vertical, single bulb reflectors with a remote ballast.
I agree, it seems very counterintuitive to me that the ballast be attached to the reflector. I personally only offer fixtures simply because a significant percentage of growers favor them these days. Ballasts produce heat, are sensitive to heat thresholds which could trigger protective shutdown. Doesnt follow to me to mount it in the room where it contributes to heat, let alone directly next to the bulb which emits the majority of the heat being produced. The exception here is that for our brethren in colder climates, they may WANT the extra heat.
Here is a link to a DE vertical fixture if you should choose to explore 630DE. There are a variety of LFSW 630 ballasts out there of varying cost and quality. Good luck.
