Wafer was designed for the discriminate consumer who wants the low profile look of recessed without the high cost. Manufactured with die cast aluminum, Wafer by Maxim brings ultimate heat dissipation to its edge-lit technology. Edge lighting gives very even light distribution  (so no "hot-spots) while dispersing heat over a larger area. The result of this is longer LED life and better light diffusion.
