RHPs don't use that much power, they actually end up saving you money, especially if you have a proportional thermostat like a herpstat. AP will install your panels. Pro products ships panels directly to them and I'm sure other companies will too. Fluorescent lights and led lights are not enough to keep ambient temps up, however, the right sized RHP will not need help keeping ambient temps up unless the room where the enclosure is gets very cold.
That's my set up. Two t8s both with and RHP ran by a herpstat 2, and led strips just for light and looks.
