250W MH/HPS in cabinet (heat question)

Im planning on building a grow setup inside a wardrobe cabinet and am having trouble finding out how hot a 250W HPS will get once inside a smaller area. (dual ballast mh/hps)

I believe I will have adequate cooling - about 200 CFM intake and 300 CFM exaust for a space thats 2 x 2.5 x 6. (or is that too much?)

I really didnt want to go fluorescent unless I had to because of the heat. If I found a 175W somewhere, would that be cool enough?

Maybe if I drill a hole in the side and exaust the light directly? (dont higher quality lights have air cooled options?)

Heres the light I want to get
Sunleaves Pulsar - Two-Way Mini 250W MH/HPS

Thanks for the help!

Bulbs sold separately ?. seems like alot of money for hood and ballast.
check the high tech garden site, you'll find a better deal there.
good luck
