hey chameleon forum this goes out to people with multiple reptiles whose electric bills are sky high. i have 7 reptile all using 75 watt heat bulbs and 15 watt uv lights. it is expensive to keep all these but i do anyway because i love my reptiles dearly. BUT i have discovered a new way to heat reptile/homes! I DID NOT PERSONALLY CREATE THIS but many people do this with great success! go to youtube and type in "how to make soda can heaters" or "soda can heaters" this is all solar power heaters using no electricity and keeping your reptiles and homes warm! thought i share this with the forum members! hope you guys enjoy it!
