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.

Also we should keep in mind that T5 bulbs at 36" long are not 54Watts they a re what 39W?
Not sure if this makes less ,heat but less light for sure compare to 48" long bulbs

Hey Melina, can you pls tell me how much light spill do you have from you 36" Tek T5x6 unit. ?
Is there a lot of light on the walls etc.
Say if you are at the front of your tank on a chair and the light fixture is above your eye level do you have bright area in view?
THX.

Check this out.
Scroll down for "hahnmeister's" tests and pictures.
I wonder if any of you guys agree with his statement about T5 sun bulbs.

If I wanted more from the T5s, I could use sun bulbs rather than aquablues, and use more blue+ or daylight lamps rather than the true actinics. Actinics really handycap the T5s overall output. Likewise, I could run the pheonix on a HQI ballast... so things even out.

So you think that by doing the reverse cycle I would be able to get by without having to buy a chiller? The MH light fixture that looked at comes with built in fans and I wonder if that really helps to get rid of the heat.
