TEK fixtures dont have cooling fans and in a test conducted on another forum, the par was like 150ish at 20" vs. some other fixture that did have fans had a higher par-rating of like 320! i dont think im allowed to post the link to that forum's thread so i wont (but it was like 22 pages long). basicly the more bulbs the merrier. just my .02 im looking at the aquatinics 5x 54watt fixture for my 55.
t-5s without reflectors are nowhere neer compared to pcs they still have way more par but with less wattage, and if u look at the thread that ur talking about its about 120 pages long
