good call Carlos - i will check out the light with the dimmer option. i really really do not like the look of the UTH being on the side, its just so tacky looking...BUT in the interest of the toads, i might just have to suck it up - honestly though, the little one i have really doesn't seem to give off much heat at all, i mean, not even really hot to the touch - but it seems to help keep the tank at decent levels. what if i got a light that gave off heat instead of the UTH altogether?! they could have a day/night warm/cool side....yes no??
