Reflector question
    #126225 - 09/28/08 06:29 PM (8 years, 2 months ago)

So I'm slowly putting together my lighting system from a variety of sources...got a 1000w HPS light for flowering, a 1000w MH for veg, and a hydrofarm daystar reflector.  It was my intention to get the convection cooled reflector but instead I got the one with 8in. flanges; the problem is, I'm not sure what I use  them for.  I've seen the pics with the ducting on either side, is the ducting attached to a fan system or into an external exhaust?  Just need some help deciphering my equipment.
I'm also thinking of splurging on a 1000w lumatek digital ballast...your thoughts?

The flanges are for hooking up hoses to in order to cool the light down.

Can't go wrong with the lumatek. I love em.

I understand what you hook up to the flanges, but to where do you run the hoses?

well, i've never worked with them, but i think there are a couple of ways to tackle air-cooled reflectors. the easiest way would probably involve a fan which draws air from the room, through the reflector and out some ducting to an external exhaust. more complicated setups might employ "light-only" air which is ducted in, across the lights/reflector and ducted out to an exhaust.

When you say hoses, are we speaking about ducting? There's a place to hook up the ducting on two different sides, right? If so, then saltatory's response is, as always, the way to go. :grin: It really isn't necessary to run the exhaust for the air-cooled reflector separately from the exhaust of the grow-room itself unless you are really struggling to keep your temperatures in check. It would require another extractor fan in order to do so.

Splurging on a 1000 watt digital Lumatek - that's wild. From what I recall, regular 1000 watt ballasts cost twice as much as the regular 600 watt ballasts, with the 600 watt digital ballasts costing twice as much as the regular 600 watt ballasts..... a 1000 watt digital ballast has got to be a good chunk of change. :lol:

What floorspace will you be working with?

Yeah Sirius, they're a bit pricey, and I was just kind of tossing the idea around actually.  I've got an older 1000w ballast over in the lot right now, and another two just sitting around the house (yes I have three 1000w ballasts, I got them on Craigslist on the cheap) and all three work, so I might just use the ones I have.  I was tempted by the promise of a higher output by a digital ballast though. Do you think the difference is worth the money?

I've got a 324 sq. foot room (18 x 18) I'll be using for the grow, but I'm going to be putting up panda film to shrink it down...if I only do one bed it'll be a 5ft x 5ft. bed, and if I feel like going big, and using two of the ballasts, I'll do two of the beds not sure if I feel like doing a massive grow right off though.  My light is rated at 150,000 lumens, that should cover a 5x5 area right?
