dont skimp out on lights, everyone here will tell you your lights are probably one of the most important if not THE most important part of a setup for a healthy cham life.
a ceramic or plastic clip dome light can be found many places for less and $10, and a 40 watt house bulb is what, $1.50 for a 3 pack? which give you a grand total of ~$12 for a proper worry free basking light
youll hear this many times around here, WHen you got into the hobby of keeping chameleons you knew it wasnt a cheap hobby, skimping out on a basking light is like buying a Ferrari with no motor, uterly pointless
