When I changed from 600mh to the 630 LEC I didn't see a decline in heat. Might be a tad bit more in my DR 150. Using the 630 I notice some heat stress on the plants.

Philips 315w CDM Elite (CMH)

If you're talking about the sunlightsupply 630w lec, that mother runs stupid hot compared to the C/G's. I can easily hold my hand 1" under the bulb tip on my C/G's. My hoods are cool to the touch at all times. Running the lamps horizontal in that stamped hood traps a LOT of heat, and creates two large hot spots under the hood. They have a demo model at my local store, and the top of the hood gets pretty warm as well.
Maybe it was light stress? I notice some when I first switched to cmh.
I would be very, very cautious about running those in an open fixture. It's a no-name company doing some type of knock-off. The projected life is half the Philips lamps.
No thanks.
The only thing I'm concerned about is if it failed with me near it. Here is the Phillips. It says life span is 20k vs 15k for the knock off. I think that's not correct should be 30k. Mogul should be rated for open fixture. If it comes with any Specs I will post them

You're measuring the amount of heat not escaping thru the walls of the tent.
After checking, the Philips ED37 lamp actually does have a 20k hour life. It is the PGZ18 version that has a 30k hours life. The internal operating pressures of the Philips Elite series lamps is roughly 10x that of other lamp families. Whether or not that holds true for the knock-off is unknown, but.....
Average life depends what Philips website or spec sheet you check,

Philips and their infinite variety of spec sheets.........
It's remarkable how they shuffle information around, as well, leave no trace of where they put it.
Hi all
Just wanted to thank everyone for an amazing thread … great contributions and information. It has been good reading the complete thread over the last week, as it is possible to see how prices have come down (on some systems) and the fine-tuning of the technology.
In my situation I move a bit, so am really interested in using the cmh system in 120v and 240v situations. Additionally, I might be growing in a rented place with a room that will have less than ideal reflection - probably just flat, white paint. From posts on this thread, it looks like there are a couple of options at the moment, for systems that include a built-in 120-240v ballasts, including …

From Rives and jhhnn's suggestions (thanks for this thread rives … it is great reading), I would prefer to go with the Phillips ballast. At the moment, I have found a dpapillon 315w system from a Canadian retailer (just checking prices … http://www.optexlighting.com/d‐papillon-315w-full-spectrum/), which if I recall is a setup that Rives liked and that uses the phillips ballast.
I have previously used solis-tek hps systems and really liked them. They mentioned that they have a cmh ballast coming out in the second quarter of this year … so that will be interesting as well. Sorry for the rumble ….
I will most likely go with 10gal fabric pots using an organic soil mix - the dirt pots are about 18" in diameter, so will probably put four together to make a 3' x 3' square grow area. Just wondering if using the dpapillon with a transformer (240v to 120v) would cause any major inefficiencies or added noise.
Thanks heaps

Take a look at Cycloptics Greenbeams. Their ballasts are universal 120/208/240/277v. They also make a 377/480v version I believe.
"growbeam"?....hmmm?

Sorry my mistake twice … the grow beam should have been Greenbeam and the link should have been:

I really like the look of the GB. I haven't heard one bad report either or really any problems with them. They seem like very reliable pieces of kit.
My main concern with the GB design is that it strongly suggests having a very good reflective grow area. In my situation, the grow area will have far less than ideal reflection. I'm not sure if the other cmh systems integrate the reflectivity of the whole grow area, as much - maybe other vertical reflectors like the dpapillion 315w also depend as much upon the reflectivity of the grow area. I was also unsure whether the new PARGrow GB ballast is offered as a multi-voltage ballast or if you have to get either a 120v or a 240v (or 277v or 347/480v). The link above for the 120v/240v Greenbeams system might be for the older Welthink ballast - have asked and waiting on a reply.
Perhaps in my situation … a horizontally mounted cmh lamp (or two) would be a better way to go, like the Double dPapillon 630w system or the Sun System LEC 630 and just use a transformer (in Canada). Maybe they don't need as good as reflectivity as the GB …. so many questions, but it is nice that there are a fair few options and so much great advice.

I strongly SUGGEST you invest in some form of reflective covering for you walls. Flat white paint is cheap as shit. You're talking about a small space, so there are plenty of low cost options. With 315w lamps, you need to maximize your all around "reflectivity", or you're pissing into the wind...just my
With any grow space or lighting choice. Some of the films may be marginally better but they're not cheaper, easier, or easier to maintain.
thanks Jhhnn
The money I was going to spend on semi-enclosures … can always be put towards a better grow light.
Just wondering … for all those also renting and not wanting to drill holes in the ceiling for lighting mounts ...
Does anyone know of some good (fairly priced) grow light stands that could be used with these cmh lights?

it's funny, conventional wisdom used to say use white paint and avoid reflective surfaces because they create hotspots. Tents have changed that mentality. But some of my best yields were in closets with the walls paint brighted white.
You have to think 70 or 80% of the light is hitting the canopy directly. So 10 or 20% difference in reflectivity of the walls is not going to change much. By the time the light bounces off a wall and comes back it's already diffused out from traveling the distance.
