الوصف

Characteristics and advantages,
1. Chips: Bridgelux;
2. LED quantity:  4PCS;
3. Luminous Flux: ******5LM;
4. Ra:*5;
5. Beam Angle: *6Degree;
6. Dimmable: Leading edge silicon controlled;
7. Material: ***3Aluminum;
8. Working Temperature: PCB<*6.5℃; Shell<*3.6℃;
9. Surface: Low temperature electrostatic powder spray coating.

Material and Structure Characteristics:
1. High quality ***3 aluminum alloy;
2. Heat conduction: *4W/mK;
3. Stong circulate convection structure, double circulate convection, strengthen convection heat radiation;
4. Use MPCB board, heat radiation:2.2W/mK;
5. Procelain globe bulb use high frequence K9, equal to *6% of the heat convection heat radiation;
6. Procelain surface have 1.*8 billion micro heneycomb, to keep strong convection heat radiation.

LED Chips:
1. Use Bridgelux chips;
2. High color rendering index: RA ****5, protect eye, more healthy;
3. Higher light output efficiency, *1.3% of power are changed into optic energy(often the average fo normal chips is ****0%);

Power supply:
1. Use L***2A control chips, small current pulsation, higher reliability of power supply;
2. Micor ripple output, risit current surge, avoid shocking to the chips;
3. Temperature inverse feedback, prevent LED lighting junction temperature getting high, increase the lamps life span.
