Product Model:
What is SMD2835?the differences between 2835 and 3014,3528 2835, 3014 and 3528 are three packaging process based on Epistar and similar dimension chips.

Generally speaking, SMD2835 LED tube is newer and more advanced than 3528. Because 2835 has more effective thermal dissipation system, specifically, a larger heat sink than 3014 on the back, and 3528 has no back heat sink at all, therefore 2835 is able to take higher current and generates more luminous flux.

The form below is the common spec of these LED solutions in these days. The data is based on June, 2013.

The followings can be concluded from the form.
 
1.Larger chip, the better
 
Taking 3528 for example, manufacturer could use 10*16, 10*18 or 10*23 chip to make the LED, all can be driven by 20ma, three plans get different luminous flux. Because smaller chip would generate more heat while being driven by same current as the larger chip, it also has shorter longevity and worse quality. However, for most of lamp buyers it is almost impossible to know what brand and dimension of the chip is really being used, the only way is to conclude it from the lamp’s optical performance test.
 
2.A controversial trick
 
Higher drive current will make more luminous flux to one chip, and also more heat. 3528, 3014 and 2835 all use 10*23mil chip, but the drive current are different .It is controversial that because 3014 and 2835 have large heat sink, one chip in these packagings could be driven by higher current. However this has become the most popular design.
