I'm using a 40 or 65w house bulb for heat, depending on the chameleon, and then 4' 5000k daylight fluorescent tubes and 4' Reptisuns 10.0, one of each in each double fixture.
I absolutely love the pictures. I've used your sticks-across-the-cage look and replicated it with my own, shittier quality sticks and pushpins lol. But I wouldn't have come up with it without your pictures, so THANK YOU for sharing.
One thing I didn't take into consideration is when measuring the distance to chop the branches, I shoulda' added a half inch, because now I had to squish the screen sides in a little bit to get the pins in there and secure it. Live and learn!
