T5 Light Raises Water Temperature

[Canadianeh]

After I installed 6 bulb ATI sunpower T5 with reefbrite xho, y water temperature has risen to 80F from 78F
I hang the light about 6" from the edge of the top tank. My tank is 20" deep.

Is it normal that T5 raises water temperature? Is there anything I am doing wrong here? Help?

Ya, they do. That's another reason I prefer Leds

Yes. I just modded a biocube with an LED partially for that reason.
