This auction is for 1 tube containing 50pcs 1W high power LED emitter.  Please choose the emitting color and Luminous in the above dropdown list first.

Here is the difference between our difference size dies used(Die means the chip inside the LED):

Die Size	Die Brand	Luminous	Advantage & Disadvantage
EpiLED 30*30Mil	Taiwan EpiLED	90-100LM (350mA)	Cheaper LM/W is lower, Popular product on market (Regular stock of SatisLED and Recommend)
EpiLED 38*38Mil	Taiwan EpiLED	100-110LM/W (350mA)	Price Proper, Stable Working & Low Lumen Decay (Regular stock of SatisLED and Highly Recommend)
Epistar 38*38Mil	Taiwan Epistar	110-120LM/W  (350mA)	Better Brand, Better Quality, Stalbe Working & Low Lumen Decay (Regular Stock of SatisLED and recommend)
EpiLED 45*45Mil	Taiwan EpiLED	160-180LM/W (700mA)	Price higher, Stable Working & Low Lumen Decay  Normally used as 3W (Regular stock of SatisLED and Highly Recommend)
Epistar 45*45Mil	Taiwan Epistar	180-200LM/W	Better Brand, Stalbe Working & Low Lumen Decay, Normally Used as 3W (Regular Stock of SatisLED and High recommend)
Bridegelux45*45Mil	BridegeLux	200-220LM/W	Expensive because dies need import from US. Stable working, High Lumen performance. Normally Used as 3W  (No regular stock, need customization, Recommend)
