Big Improvement and I am sure your cham thinks so too!!! Just make sure whereever your basking light is that your cham cannot touch the top with his back or head and get burned with some of the vines being close.
I have my basking light propped up about an 1 1/2 inches off of the screen, The screen is cool to the touch and the bulb is only 60 watt which hardly puts off any heat. I'll make sure I keep an eye on it though.
