Simple Damp-Safe 10W Round Shape Constant-Voltage LED Power Supply
A modest, no-fuss power source for small LED projects. The non-dimming design keeps install simple and affordable, and the small round profile fits tight junction boxes. The plastic enclosure is safe for damp spots like kitchens and bathrooms. With active PFC, overload protection, and silent convection cooling, it runs worry-free for years — backed by a 7-year warranty.
