here is what it says on the web site...

What is like to ask is, would i be better off with a fan cooled hood and a normal hps lamp, or shall i take the plunge and give this lamp a go ?

its the only money i have so i really want to get it right...

that will work just fine. with a good air flow and exhaust you should not have a heat problem

well it does seem ideal for me actually......thanks guy, im looking at others too, but yea, im liking this one best, so far...

the only thing that bothers me is the size of the reflector....any thoughts on that pls anyone ?>

Im uk grower with a 400w hps and make sure take careful consideration on the heat it will throw out. That one has its ballast attached so will create more heat then one with seperate ballast....thats only issue I see... if heat not a problem i would go for it.

With that reflector ur gonna have to hang it pretty high above the plants or build ur own somehow...Hanging it high will cause stretching also...Or u can use it for just 3-4 plants tightly packed..JMO..GL

are you saying , based on the shape of the reflector i need to hang it high to maximise light spread ?

the advert claims otherwise with the heat tho ?

they claim it generates LESS heat

i just want a GOOD 400 hps lamp, i dont mind using air cooled either.

this one seemed to be the answer

After looking, i think i prefer this one.....can add a 125mm fan to it .
