CONSTRUCTION:• Ultra light weight die cast magnesium alloy heat sink

• Polycarbonate optics

• Oscillating diaphragm draws heat from LEDs

The BayMAX lamp features a unique oscillatingdiaphragm that accelerates the transfer of heat awayfrom the LEDs. This offers improved thermalperformance compared to traditional lamps that relyon the heat sink exclusively to transfer heat.

The diaphragm is not affected by ambient temperaturevariations or dust accumulation, and is constructedwithout frictional moving parts that would wear out overtime. The solid state diaphragm design offers thermalmanagement comparable to a cooling fan withoutemitting any audible noise.
