Tek T5 fixure. How hot does it get?

[Txcowboy22]

I am thinking about running a 6 bulb over my 46 gallon bowfront tank, I am just wondering how hot these unit get because there is no fan or anything. How much heat does it produce compared to a halide?

My 6 bulb is 4in from the water. I don not use a shield. I see a 2 degree increase with 6 lights running for 6 hours. IMO, they don't run hot/

So is it ok to run without a splash guard? Do you use any type of fan?

[scotmc]

no fan..

[scotmc]

there is no problem with no splash guard. If you do use one. It will increase your temp and your bulbs will lose life and par. If you want a spalsh guard, I would go with another fixture, with a built in fan

it doesn't matter to me as long as everything is ok.....

I have a four lamp. It don't get hot and i use a splash guard. Scotmc is right about the lamps getting hot and loosing life. I just prefer to clean the acrylic instead of cleaning everything individually.
