A sleek matte-black electronic device with a brown fan and glowing blue lights sits on a black textured surface.

A sleek matte-black enclosure, four inches square and one-and-a-half inches thick, snaps flush to a twenty-gallon reptile lid; matte acrylic lid has a recessed circle where a quiet twelve-volt Noctua fan presses against a brushed-aluminum Peltier plate-heat or cool air blasts straight down through mesh. Same lid holds a slim ring of diffused LED strip, white-blue-purple glow leaking around the edges, plus a five-percent T5 UVB bulb tucked behind a frosted cut-out, glowing cobalt. Air in through a whisper grille up front, out the back; no wires dangle-everything routes under the box via silicone-sealed grommets to a tiny Pi Zero and step-down buck converter feeding a matchbox-size wall-wart, all hidden flat on top.
