According to Phillips the bulb is supposed to be mounted open and vertical. Philips has 3 types of 315W bulbs: T9, T12 and ED37. T12 and ED37 are "O" rated, can be installed in open fixture, T9 is not "O" rated and should be installed in an enclosed fixture. All three bulbs can be installed vertically or horizontally. On Philips website page, it says, "Operating Position: UNIVERSAL [ Any or Universal (U)]". Here is the link:
http://www.lighting.philips.com/main/prof/conventional-lamps-and-tubes/high-intensity-discharge-lamps/ceramic-metal-halide/mastercolor-cdm-t-elite-med-wattage/928601167131_EU/product

These reflectors are designed to maximize the relatively low power bulb. Could you explain?

And according to the university of Utah that setup with the 3100k bulb is the best single light source for full plant growth. If you can run a PhilipsT12 942 bulb at higher power, such as 350W or 400W, you will know which bulb is better.

And growers house shows highest par that way. Please read my explanation above and below.

And I wish I had the commercial test I found last year but it is gone with my old phone. It showed highest par under the sun system vertical reflector at 16” over. 2.5’ x2.5’ area. Suppose all (ballast, reflector, lamp, etc) are the same, anyone know that you can get higher par over 2.5' x 2.5' than over 3' x 3'.


All I am hearing from you sir is opinions and customer comments.

All info was found in university of Utah testing. I am sorry I no longer have the links.

And running bulbs at higher wattage than they call for would completely ruin the whole point of the 315. Efficiency.

Also regardless of different bulb orientation (different bulbs were produced later after initial hype) the vertical open fixture was designed specifically for the Phillips 315 cmh. Sun system and cycloptics both consulted with Phillips on design.

And I meant to match Phillips specs for max par the company I mentioned found it was really at 16” and only 2.5x2.5 area.

My testing confirms plants struggle at 3’ edges in an open room. I suspect a 3x3 tent with reflective sides will help with that.

And I am doing a run in a 3x3 with the Phillips bulb in the sun system reflector now.

Seems plenty jumped on the bandwagon after the hype set in with a bunch of off brand cmh products.

I dont trust companies that do that.

I think the 315 is probably the best 3 x 3 tent light every developed. For efficiency and yield in the space for personal use. With a 4 inch profilter or canfilter it is smell free and will fill the space easy. And tower fans are the shit.

I switched back to the 3100 because i am neurotic about the slightly loose glass shield. The critical mass are going bonkers. The SD are not so much. But it can be pheno and weirdness so I will top till i fill the space and let it flower.

He got 22 ounces dry from 2 plants in a 3x3 tent under 1 SunPlix 315W light.

Just vegging my babies then swapping out for my 630 I got for flower. The 630 in my 8x8 at 5 1/2 to 6 ft up was too much light at the stage they were at. However they should rock though when it goes back in for flowering. I'll have to grab up a 315from you here soon for vegging purposes.
