Is Anyone Using Phillips 315 Watt Ceramic Metal Halide?

I flipped all my hid's to cmh after I got my first one. I run a 630w in a 4.5×4.5 with 1 3k and 1 4k lamp. Also running a 315w in a 4.5×2.5 4k. Pic 1 week 5 day. Pic 2 21 day veg.

Subject line says it all: Is anyone growing with Phillips' 315-watt CMH bulbs? I've read that they blow away 400-watt HPS, but IDK. I also don't know if they are available for mounting in a horizontal orientation or vertical only. Looking for reports/reviews from people who have experience with them (preferably the ones designed specifically for growing plants). Thanks!

I have been using a 630w cmh for over a yr. now, and it's a great light, as long as you can control the heat from the open reflector. I've never used 1000w hps, but I can tell you it blows any 600w hps away. The newer ones now have an air cooled reflector, which will cool everything down to a usable climate. The 630 gets vented to a neighboring room.
Recently I got another 315w cmh, thinking it would work well along side a 430w eye hortilux. I'm on my 1st. grow with them both in the 4x4x6.5 bloom tent. now i'm thinking about one with 4200 bulb, for my veg area. And that will force me to get an exhaust fan for veg room. Now, I'm just leaving the door open to the tent, with current t5s. Hope all is well in your world ?
