You need LEDs. Either the strip type that mounts under cabinets to light up counter tops, or the regal screw in types if you have a normal light socket. Be sure to get one in the 5000-6500K color range. Most of them are 2500K and they look yellowish. This info will be on the package.I’m having a hard time finding an ambient lighting source that is a low enough wattage that it wouldn’t really affect the overall temperate of the vivarium. Regular bulbs are too high in watts so I was thinking perhaps a really low UVB output bar? Thoughts? View attachment 352215
