The 4 inch COB LED downlights adopt high quality Sharp COB LED as light source,
guaranteeing single bin color consistency with enhanced illumination uniformity and minimal glare.
Unique die casting aluminum heat sink keeps the LED junction temperature below specification,
enabling cool operation and maintained lumens. Various wattage range from 10W to 15W available
for universal use in commercial and residential lighting project. Compared with conventional down lights,
they can save up to 80% electricity and energy. TOBS 4 inch LED downlight retrofit are the ideal replacements for 60- to
100-watt incandescent lamp in the industry's most poplular 3.5- and 5-inch recessed dowlight fixtures.
