Heat Sink

Heat Pipe technology is used: better cooling for chip


50W COB  

Beam Angle

Optimal Protector of LED: Phase-change Heat Sink with Heat Column (Updated Heat pipe)
Heat-transfer Core Of Heat Sink: Heat Column High Thermal Conductivity: Far more than any material Low Temperature Starting Working: Less than 28°C China Invention Patent: No.ZL 2010 1 0162168.4 Chimney Convection: Enhance Cooling
Comparison between Heat-column Heat Sink and Normal Heat sink Different Cooling Effort depends on different principle. More protection for central LED chip
