The way I explained the way I do my lights is a sure bet way and I am not saying there aren't other ways.... but being around I've seen lots of patch work and it just ends up being easier and better for the animal if you just change things for the better rather than worry about money that might be wasted. and I don't mean that in a scolding way. But if you think about it, you'll spend the money making the change over, the damage is done, why make the animal have a questionable setup when you could just simply improve. Now, if you don't have the money to make the changes, the MV light might work if it is a lamp worth using. But a ton of UV lights isn't going to matter really. The chameleon needs to be able to get away from it, not have the UV following the animal's every move. They can regulate their exposure, so an area of the top of the cage that isn't 'covered' in UVB is fine and beneficial. I would just keep the 6500K lights on the cage in a even spread so that you have a good amount of light for plants and animal and make sure you provide a basking area, and in that area have UVB so that the animal is exposed when basking. Basking is the best time for UVB to be exposed to the animal too. The skin can better process the vitamins and produce D3 via UVB with warm skin from the basking lamp.
