Now on the market sold a lot of light source products to cut corners, such as the use of 5050 SMD 18-watt light source, patch number should have 90, but practical and not so much the better to distinguish, if some manufacturers of the 3528 posing distinguished 2835's this bad. So how do you distinguish between 3528 and 2835 lamp beads lamp beads it?

2835 lamp beads have the following characteristics:

1, using the entire surface emitting programs, high luminous efficiency, the light-emitting area of 9.18MM, 2 times 3528 lamp beads, 2.5 times the 3014 lamp beads.

2, high brightness, single up to 22 lumens (LM), the brightness is 2.8 times 3528 lamp beads, 3014 lamp beads of 1.8 times.

3, lamp beads thin thickness of only half 3528 lamp beads, light-emitting angle of 120 degrees, in the finished application, the spot is more uniform illumination broader.

4, SMD type lamp beads unique vertical cooling, heat sink on the bottom, chip direct conduction heat sink, heat faster.

Overall, 2835 looks relatively thin with respect to 3528, the larger light angle; Ribbon 2835 and 3538 stand layout are different; 2835 relative to 3528 will generally be able to do relatively large power LED.
