BC Series High CRI High Power Density COB LED Daylight 5600K - BC270H - Pack: 1pcs

SKU YJ-BC-270H-G01-R-56

Yuji LED now releases two types of small LES COB package to meet the market need for higher light intensity with very small form factors. Yuji LED’s recent compact-LES COB – BC160H, BC270H – remarkably reduced dimensions. In the100W-class BC160H, the diameter of its LES has scaled down 9 mm from the 40 mm typically specified in conventional 100W COB packages. For the BC270H offering, the LES is only 19 mm. These LED packages are highly compact and their LES is extremely smaller than the most existing COB packages in the market. Moreover, they provide the exceptionally high light intensity and even higher Center Beam Candle Power (CBCP). These offer compact and bright lighting solutions for spotlights as well as high bay lights.

1) High CRI of 95+

This product is very suitable for applications in film & theater, where high light quality in a high light output format is necessary. 


2) Small LES (Light Emission Surface)

With a diameter of only 19 mm, the Yuji BC 270H COB has the smallest emission area for an LED of its power class. This allows for very high power densities where there are size limitations, and also allows for excellent optical controllability.


3) Customization requests

Building upon its existing families of SMDs and lower power COB LED platforms, we extend our SPD and custom color point customization capabilities to our newest LED platform.


4) Power supply recommendation

We recommend Meanwell HLG-600H-42A.  


5) Three options

We provide the high power COB as two versions of: without radiator,  with radiator to match different requirements.
