1. Osram/Sharp/Citizen LED Light source, >90~120lm/w, meet the LM-80 Certification;2. Sufficient illumination:LED is available immediately and it can be reach at the expect lumens,without swift loss.3. Low lumen attenuation: High quality constant current driver and good heat dissipation techniques4. Cooling fin structure: Innovative Die Cast design, adopt high-thermal conductive material AL1060.
