What kind of chameleon? How old? Please post photos of your current setup and your animal to an imgur album and link that album HERE IN THE COMMENTS. DO NOT make a new post for this.
For products, I found that chewy.com was pretty good. Amazon of course, but if you wanna avoid giving Bezos more money, check out the actual company that's listed as the seller once you find the product you want.
List of products that I use/recommend and are well tested and vetted by the community:
8.5" wide angle dome to disperse heat in a safe zone. 150w max with dimmable switch.
don't forget supplements. You need to get yourself
Calcium WITH d3 and no phosphorus. Again, rep-cal brand is good here.
FLChams safe plant list. Plant that baby up, but make sure you don't go too crazy lol.
Get rid of the heating rock. That's dangerous to the chameleon. Get rid of the humidifier. Also dangerous.
Read ALL of the articles in the sidebar/about section of this sub and r/chameleonsfaq. It's good to have the knowledge in your mind before issues arise.
Next time please invest more time into properly researching and setting up before bringing a chameleon home. You should have had their habitat set up and tested before purchasing the chameleon.
