Factory who manufacture offroad LED light bar,LED work light mush room.While as a saying goes:every penny worth.Take LED light bar as a sample to see how Sanmak is different:
 
1. Difference on LED  
Sanmak:use USA Cree XBD 3W LED chip.While other suppliers use fake Cree chip

2. Schottky Barrier Diodes

Provide reverse connection protection
 
3. IC   
Sanmak:2 on each 18W PCB board. Brand：CRpowtech
PT4115 Step-down High Brightness LED Driver 

4. Resistors  
Sanmak:2 on each 18W PCB board. Brand： Yageo

5. PCB board   
Sanmak:Lead-free PCB board with thermal conductivity being 1.5. Ensure good heat conduction and long LED lifespan.
Others:Much thinner PCB board with thermal conductivity around 0.6
 
6. Capacitors  11 on each 18W PCB board. Brand:Murata  
Sanmak:Except the capacitors with energy store&power flow stabilizing functions, filter capacitors are also added to attenuate EMI
 
7.Chip beads   
Sanmak:4 on each 18W PCB board.Brand：Yageo
Attenuate EMI/RFI      
 
8.TVS(Transient Voltage Suppressor)

10.Anti-interference circuit passed EMC certification
 


With 10-years-exoerienced R&D team,Sanmak develop and launch new light every month.We design unique one .
While others use public moulds in the market to save cost and just copy whatever popular in the market.
