I ordered my double fixture from http://www.lightyourreptiles.com/ it contains a 6% and a 6.5k which is working great so far. My cham and plants are not complaining:D
I have a couple of lengths of 1x2 that I use across the top of my cage to lay my dripper on top so that it doesn't sag the screen or being limited to the corners. Works great for me.
