Privet,

Fire belly toads are diurnal toads that are well known to bask. They do best under UVB lighting and it's not like a UVB bulb costs a fortune. Also, I'm not sure but regular shop lights might produce the wrong rays and be dangerous, it's better playing it safe and getting a bulb you know what it emits and how much UVB. http://www.exo-terra.com/en/explore/uv_rating_index.php

Exo Terra claims that moss is safe but I've had a horned frog get impacted on it and I had to bath it and it crapped out the fibres within a few hours. I fed the frog with tongs but because the moss is so lose and has small strands it's easily picked up. Sphagnum or cushion moss is best
