Ok so.... While this light can be effective for other species of reptiles that are in a shallow enclosure it is not effective for a Chameleon. Reasons are... The cham literally has to be sitting directly below the fixture within about 7 inches... The uvb light ends with these bulbs by 8 inches below them. What we see as light going down say 18 inches is not the uvb light it is just the visible light from the bulb. Having to be so close then puts the cham also at high risk for a thermal burn. Where the concern is.... chams can develop MBD when they do not have the proper UVB lighting.Sure but I have been told that this is exactly right by several others and it seems to be working just fine.
I'm aware.. but you're saying your UVB is fine because of where your basking branches are, but the only spot in your cage that is within the UVB is where your 2 vines meet. That is the ONLY spot in your cage where he will get any UVB at all. He should not be confined to that one spot for his health.He doesn’t sit there all day..... in nature chameleons are in trees and out of direct light for parts of the day. They hide.
