I've done enough research before starting this thread however I was unable to find the type (T-8 or T-12) of the fluorescent UVB Reptisun tube for 48 inch long models. I have bought 4 48 inch cheapo T-8 fixtures and tubes (Phillips daylight deluxe and coolwhite) to go along with the UVB tubes. the canopy will have 8 48 inch long tubes where 2 of them will be UVBs.

Should I go with 10.0 UVB or 5.0 UVB tubes for a 2 x 4 x 4 enclosure that is divided in the middle for 2 chams?

If you happen to use 48 inch UVB tubes in your enclosure, please let me know of the type.

Thank you.
