Hi Im new to the group..I have a 10 month Refoot temporarily housed in a 20 gal tank with a 60 w daybulb in daytime and off at night. My house has been warm enough at night but with the cooler weather coming I am looking to upgrade my heat-light source. Can anyone tell me what unit or setup is best? I was thinking about one odf the combo lights which hold a tube plus 2 incandescent? If this is good what wattage should I use in my 68-70 degree house. thanks Linda
