After reading this thread many times, in the last few months. I have finally decided to take something from it.
-So, I purchased Arcadia bulbs from lightyourreptiles.com Todd is GREAT!
I added a 12% UVB to my old zoomed LED/UVB 24 in fixture.
and a 100W arcadia mercury vapor and 75W arcadia halogen.
(These are the lighting requirements I found on the Arcadia website).
I completely agree with 'chameleopatrick' about a general warm area, instead of a hot spot. My bulbs are 7 inches from the top screen. creating a basking areas (instead of spots) of 100F at its max. My panther chameleon, tends to hang around the top section more now, compared to when it was a hot spot.
My cage is 5 ft tall. with dense live foliage, giving him more than enough spots to avoid the heat and UVB.
I honestly recommend, that everyone use Arcadia products, and LEDs if your going to use live plants.
