I have no issues with the CFL, even in a small tent. The LED creates far more heat, but still manageable. I am getting a taller tent (should give me an extra 40cm). I can't see why they don't have the ballast outside the tent. One I saw was bolted onto the side, but was taller than the hood, which I didn't think was a good idea as it reduces the height you can have the light[s].
IIRC I did see a video which said that although the Philips one was the most popular, it was far from the best. I'll see if I can find it again.
Thank you for your input. Much appreciated.

you cant really tell which lamp is in this pic but the fact the lamp is on and the photo is as clear as it is is proof enough its CMH. this was a pound grown on a single 315w it is easily doable with good canopy control
buds were frosty as hell as well. strain was dream beaver by bodhi. one of my favourite grows ever i must admit

May be same watt to watt but massive difference £ to £ to buy. It would take a load of superior grows to get your money back for the set up cost.
Mate of mine uses on as supplemental lighting and just had his best grow to date , but that could just be the EXTRA light.

I'd like to know if I could pair a 315w CDM/CMH bulb with my digital ballast, the closest wattage output would be 275w/400w with 400w being preferred. Cant see this working and probably not good practice as thats quite a jump in wattage over spec
