Low-e would suprise me, isn't that refuring to the gass they put between panes of glass in energy efficient windows?

Here's a photo of the corner of the glass used in my fixture. Some of the writing has worn off.

Steve, I think the gas in thermopane units you are thinking of is argon. The low-e stuff is a coating on the glass and I have no idea if it beneficial or not.

actualy your right, I checked to see what the windows I was looking at are, it is a chemical coating that reflects light energy and only alows aproximatly 75% of light to pass through... hmmm sounds like something I wouldn't want on my tank.

Just get tempered glass and raise up your lights to about 6" over the water if you can.
