The only ones I've seen that are plastic safe are the 4x4 ones for 5 gals. (But they're made for kritter keeps, and bins seem to be thinner than those KK's, I'd try it on an empty enclosure first.) I'm hoping each light I use can eventually cover 3 enclosures... that is, once I get a shelving unit. Clear tops would haved help, but I have white.I've started using those because of their lightness / stackability / cheapness . . . but is it possible to use a side-tank heater on them?
Any updates airforce?
