I agree with Summoner,so to finish if you want a more advanced lighting system you can combine your(24 inch T8 20W REPTI GLO 5.0)or a(24 inch T8 20W REPTISUN 5.0)with a fluorescent aquatic tube like a(24 inch T5 or a T8 20W LIFE-GLO)tube,they are made for aquarium use but experience chameleon keepers use them to stimulate plant grow,from your pics you dont need the more expensive T5 setup,go with the(24 inch T8 20W LIFE-GLO)schefflera and pothos will grow nicely and keep their creamy coloration under a T8,you dont need the EXO TERRA or ZOO MED linear fluorescent light fixture canopy its to expensive for no reason,use a 24 inch t8 fixture from home depot....like Summoner has described or you can use EXO TERRA T8 ELECTRONIC FLUORESCENT LIGHT CONTROLLER,they have long wire end-cap leads so you can place your lights individually anywhere on top of your cage.
