Issues of Automotive SMD Led bulb

What's led chip are you use in your SMD led chip
Middle Power SMD Led chip SMD2835, SMD3020 and SMD3030

Why do you use these SMD led chip?
2 times brightness than SMD5050, about 120LM per watt

Good light beam pattern

Wide range brightness

I found a issue why do your price is a little higher than others?
There are 2 reasons

1, We use aluminum PCB not fiberglass board, because alumimum PCB is much faster heat dissipation.

2, We use constant current PCB driver not only just resistor driver.

How do you make sure your prodcuts quality?

We have 7 steps testing

1,  Led chip test

2,  Driver PCB test

3, Semi-finished led bulb test

4, Driver test

5, Led bulb test

6, New products 72 hous Aging testing, old products 2 hours Aging test

7, High voltage test

which products are very popular now?

G series and K series are very hot sales in the market now.
