14w led tube light t8 900mm ce rhos approval fluorescent tube

Feature of 2835SMD tube:

1) Large Heat Sink: 2-3 times bigger heat sink than smd3528/smd3014, excellent heat dissipation structure  design which reduces light decay and makes the lifespan longer

2) Large Light Emitting Surface: can improve the light-extraction efficiency to 90%.

3) Ultra-thin structure: will solve the long-standing light spot problem of smd3528 and smd3014.

4) High luminous efficiency: the luminous efficiency can be up to 90-100LM/W.

5) Super stability: low light decay material, mature technology and production process

6) Low cost performance: can save 20% cost to achieve the same lumen flux.

7) Color temperature: can be lower to 2000K, up to 105000K.

Generally speaking, SMD 2835 design is newer and more advanced than 3014. 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.

Remark: generally the shipping cost will based on Volumetric weight because the carton size is big. Such as 120cm tube = 135x25x25/5000= 17kg~18kg depends on actual measure by different Express Companies.
