I'm starting to rethink this CFL... HPS anyone? (150W)

I have a cab thats 3x2x1 and I was going to put a bunch of CFLs in there, but the CFLs do get hot, and I've found evidence that 150W of CFL puts out the same heat as 150W of HPS. So I'm thinking about grabbing the 150W HPS with separate ballast.

Currently I have 48W of CFL and one 34 CFM exhaust fan (I know not much) and it's holding steady at 80 degrees with humidity at 29.

Do you think that if I had a 100 CFM exhaust at the top and the 34 intake at the bottom I'd be able to get away with a 150W HPS (ballast on the outside of course). Maybe with the lights on a 20/4 cycle.

I threw 150w of CFL and incandescent light in there (2/3rds incandescent) and the temps only got to 91 with my little 34 CFM fan at the top. Early tests are looking promising... if only I had the bigger fans right now...

Thanks for the replies in advance!

i did the same... switched from cfl's to hps half way during veg

as long as u keep the room well ventilated heat will not become a problem

HPS is the best option almost all the time, and you learned a lesson very few believe, 150 watts of light puts out the same amount of heat as 150 watts of light from another source everytime. No one wants to believe it.

haha it's totally true. I read this huge post about it, it's not about the watts, it's about the lumens. That is the only unit that truly gauges how much energy, and therefore heat, is being put off. If those ratings are equal, heat is also equal. Only thing is generally watts and lumens goes hand in hand so it is often said in that way. At least thats what I think it said... when it comes to lights anyway.

Oh well, the point is, it's true.

The main heat source with CFLs is the ballast.

Two different bulbs do not produce the same heat, even at identical wattage. Different bulbs have different rates of electron -> radiant flux conversion(this includes all EM radiance), and electron -> luminous flux conversion(basically, what we really want from a bulb, visible light), as well as convected heat generated by the conversion process(ballasts, arcs, etc.).

You can go to this place

http://www.e-conolight.com/

and look at

E-HC1H151Z

it is a 150 watt hps floodlight for $42.90, they got rid of the $30 light. I like this one better anyway. A 400 watt hps is $115 there but you might as well spend $40 more and get a fixture from HIDHUT for $159. It comes with electronic ballast, reflector and bulb. It is also plug and play, goes together nice and easy.

For $42 you ae getting a pretty nice light or at least they used to be pretty good quality. If this is your first jump into HID lighting I'd say give it a go.

Let me know what you think, this should be way nicer than what you would get at lowes or home depot, or if you have any questions let me know.

Actually it doesn't look too bad if you want to give it a try. The only thing is I remember they had trouble with their bulbs for a long time so you might want to order a seperate bulb from another company to go with it. It's probably worth a try if you want 150 watter.
