when I got my Fluval Edge last Christmas, I wanted to upgrade the lighting so I went about the upgrade as quick as I could.
The first thing I did was locate a local lighting company (look for a place that sells to local businesses) to pick up mr16 sockets. The reason for this is so you can utilize both mr16 and mr11 lights (it gives you a lot more options lightbulb-wise).
The install was easy, just a few cuts and a few wire screws and your good to go.
Next step was ordering mr16 led light bulbs from http://www.ledwholesalers.com/store/...ewCat&catId=52
Make sure to look for bulbs that are NOT open face, the evaporation will destroy open face bulbs really quick. The other option to prevent this is get a small piece of glass cut and simply lay it on top of the Edge's opening.
The final step was purchasing and installing a CFL fixture in the hood on the swing arm. I opted for a 10w Coral Life 50/50 bulb. Individual preferences will dictate, but I didn't want too much light and the blue make a pretty nightlight.
I picked up a simple socket and (grounded) plug from Home depot for about $12 total and simply zip-tied the socket to the swing arm for the lighting. It was a tight fit with the socket I got but it worked great.
Hope you find this helpful and good luck on your lighting mod
