So I just found some 10 watt Daylight 6500K energy smart lights in the lighting department at Walmart. They fit into my tank hood so I figured they would be perfect! They made the water look gorgeous, so much prettier than the incandescent lights. But after 5 minutes of being on, I felt them and the little shield over them and they were making the plastic shields hot. I'm completely paranoid about fire and shorting stuff out, etc. Should I take the plastic shields off of the hood and leave the lights exposed? Are these lights the wrong type of light to use in the 10 gallon hood? On the tank hood, it says to only use tubular lights, I don't know if I should be ok to leave these in or not! Thanks for answering such newbie questions!!
