high technology 4000-4500k beam angle 120degree 4ft led tube

2.Top quality PC cover
For our led tube, both transparent and milky covers are available. For milky cover, when lighten the tube, LEDS are invisible. Namely, light effect is very even and same as traditional fluorescent light. We realized 100% perfect replacement.

3.Great Lighting source
The chip of led tube is of high quality and bigger size, 10*23 chip, which is from Epistar in Taiwan. It can resist higher anti-static and distribute more brightness.

4.Low light attenuation
The white light is adopting new technology, less than 3% in 1000hrs, however, the
traditional attenuation of white color at least 30%.

light intensity of 4ft led tube can not avoid.But we control it well.
1,best quality PCB,heat transmitting coefficient is 1.5.
2,led current can control in safe scope.           
3,use constant current driver.
4,high quality half AL and half PC structure is good for heat dispersion
5,Use best chip and SMD production independently.
