I use the same brand but the quad fixture it works great however it comes with 10000k lumen bulbs you may want to switch for the standard 6500 I'm not sure what effect the 10K would have on the chameleon or its eyes but I'm sure the plants would love it
I noticed the link is for the 36in you have a custom enclosure also side note you may want to consider the quad bulb fixture it's not that much more and has been well worth it in my opinion
