Oh, BTW, I went with the LEDs you linked to above...... They never lasted more than a few weeks, so while they are cheap to replace, you'd be better off asking Jenn about the EcoPicos..... Six months down the road, they'll be cheaper than those bulbs in the link.

This is my Fluval Edge build thread.... Lots about the lighting I tried......
I'm very happy with the EcoPicos
