LF: 36" T5 Light Fixture

[tang daddy]

T5 can be more expensive than mh now if you go witha 400w then you will need a chiller just think about it this way tek t5 with 6 bulbs how much wattage are they combined as oppose to a 175w mh think the heat issues are the same the only difference is the money you save in the end changing 6 bulbs vs changing 1 also if you live in an all glass apartment then you should be investing in a chiller or going with a reverse cycle on the lights for the summer I had a 175w mh all winter long on my 65g it was fine now I have a 400w mh sitting 4in from the water and when it's 30 outside with the lights off, tank sits about 27c at 5pm when the lights go on 27.2 at 6pm 28 so I got a chiller, my 30g anmone tank no chiller on a reverse cycle 26.7 all night strong the light sits right on the tank so you don't really need a chiller if you run your lights at night for 175w mh but 400 is debateble hope this was helpfull.
