To replace a 600 I would run (2) just my opinion one 315 is more like a 400 watt HID........
My hydrofarm(looks like that one in the link) has a kit for glass and ventilation. But I found no need in my application. The heat is much less even in a '4x2' tent. I have 7' tents with both exhaust and intake fans.
Sweet, it is ok to air cool a 315 CMH? i was going to put this conversion kit in my 6 inch block buster and air cool like i do the rest of my lights. What do i google to find your thread?
Sunlight supply makes air cooled LEC reflectors.

Found your thread as well
Double glass jacketed lamp is rated for either open fixture use (without glass lens) or enclosed fixture use (with glass lens). Bi-pin lamp base is compatible with all Sun System® LEC® Brand Technology Fixtures.
It will be fine. It is just also rated for open use.
<3 thank you guys, love this section of the forum, so many helpful people , information and awesome bud pics
Wish i could give you guys more than one like.
Yikes that's a bit scary , good thing i'm putting these under the glass but that will definitely be on my mind now
Open Rated lamps are okay. Make sure you get them if you run your lamps outside of a sealed, glass enclosed fixture.
