Strictly T5 thread

Keep in mind that PAR drop reported by ihavecrabs is with a fixture that isn't actively cooled. Of course you're going to burn the schnikeys out of the lamps without active cooling (in addition to getting lower PAR values). You're better off going with a higher quality fixture than a TEK because in the long run your lamp replacement costs will outweigh the up-front difference in the cost of the fixture. Comparing a TEK fixture to something like an ATI, Sfilligoi, Fauna Marin, etc. is like comparing a Seaclone to BK. I'm sure there is obviously some PAR drop in the better fixtures but I doubt it's as rapid as the uncooled TEK and comparable fixtures. This is one of those cases (similar to skimmers) where you really get what you pay for.

I'm going to have to get a PAR meter so I can monitor the PAR changes in an actively cooled fixture.

a big loss in par over 10 months.

Thats a very good point which is why i have been debating swapping out my TEK for a powermodual down the road, also the 8 bulb power modual is close to the same size as the 6 bulb TEK light. But yes active cooling plays a big part when it comes to the life span of the bulbs but for most people the TEK is not that bad of a fixture.

Cool, before I go and spend the extra bucks on a ferrari T5 fixture it would be nice to see the par drop in a XXXX time span as compared to the TEK's.

you can get a similar effect by running a fan across the bulbs on a TEK

I think this is a great thread. We need a thread with just pictures of the tank (FTS) with the combos of lights. This would be a big help also.

WHAT!!?? I thought my TEK light was one of the good ones??? Almost $500 with bulbs. active cooling now??? I can't win for trying.
