2x150w HPS vs. 4xT5 + 150w HPS????

Hey guys. first post in here. but i've been a lurker for waaaaay too long. so i'm setting up a small grow cab for scrog dimensions roughly 36'' high x 36'' wide by 20'' deep. So my main concern is ventilation. I've come across these two light systems. anyone have an opinion of which would be better for both veg and flower?

150 watt HPS grow light 400 600 1000 mh t5 cfl clones - eBay (item 320224414672 end time Mar-06-08 18:41:28 PST)

(does that look legit? looks kinda homemade. and im not sure of the "cool running temp" claim. looks waaay too enclosed)

vs.

Sunlight Supply Spectra Max 246W HPS/T5 Ultimate Grow Light

looks kinda high tech. but yea... any input is appreciated. i just want the best lighting recomendations :thumbsup:

It looks like heat issue is going to be about the same for both systems. The T5 HO's do get pretty warm. I would be tempted to look at a 400w cool tube system.
400 watt HPS GROW LIGHT GLASS COOL TUBE Reflector 400w - eBay (item 180180080284 end time Mar-12-08 14:25:49 PDT)

Or go to a strictly T5 system.

hmmm. i understand. but 400 watts in less than 3ft of height scares me. my main goal is to keep this itty bitty cabinet stealth. so a big fan is really not an option. and i havent figured out how to fit a Panasonic whisper fan in there without losing a lot of vertical space. i am looking into cool tubes for my next cabinet (much bigger than this one)
I kind of like the idea of a few little lights with both spectrums throughout the grow... but yea. decisions decisions... haha

thanks for the reply tho. all suggestions are being taken into consideration.... my next goal is to create a mini sun using cold fusion. i stole the plans from Dr. Octopus on Spiderman 2.... dont ask:wtf:

Saw this two posts up, might save ya $70.. click on vapor tight then its the last 150 hps on the right.

PDX

the sun system spectra max is a nice light for for a small op ihave the same one and it runs amazingly cool. I have a smaller 100 w mh puts off way more heat and if you plan on cloning the t5s run about as cool as regular florecents that is what i use mine for primarily and if its your only light your running both spectrums. iwas veg with it two days t5s only third day both t5 and hps. give it a little strecth and run both during flower so from my experiance i would choose the spectra max by sun systems for all above reasons and some probly not mentioned over a no name shady looking hps on e bay. besides i havnt really seen any good deals on ebay the my local store dont have for usually cheaper discount-hydro.com hope that helps:stoned:
