Reflector Big Kahuna vs EasyCool 6 Reflector

Ok I had a 1000W HPS/MH grow light that my sister took it had the EasyCool 6 Reflector and it was pretty nice but I see HTGSupply has this Big Kahuna reflector I was wondering which some of you prefer (if you have experience with either).

I plan to put a 600W MH/HPS in 40 x 40 x 78 Grow Tent.

That 600 should carry you just fine. Matter of fact, I found a cheap one, if you haven't already gotten one... http://www.insidesun.com/defccf1686b8e72e72d9c136cba7cdf9.item

Cant beat that price! brand new 600 Watt for 200 bucks. If I needed another one, Id get it.

Thats just an HPS I rather have an HPS/MH conversion ballast that way I can use both HPS and MH and not use a conversion bulb.

Ahhh. Yeah, that's not what your lookin for...

Search that site! They got some good deals, bra'.

I think the easy cool 6 would work out fine in that size space. the NexGen 400/600 will run a 400W or 600W, MH or HPS.

The larger the reflector the farther the light has to travel to the plants. Light falls off exponentially so some of the smaller reflectors actually give off better light although the larger reflectors will distribute the light over a larger area the light will be less intense over all.
