1W Royal Blue LED (EPILED 440nm)

1W Royal Blue LED (EPILED 440nm) -

1W Royal Blue LED attached to a 19.8mm x 19.8mm star PCB. This high quality LED uses a large 45 Mil EPILED chip producing a powerful royal blue light peaking around 440nm with a beam angle of 120°.

Popular for use in fish tanks, grow lights and specialist architectural lighting, this versatile and powerful LED produces an impressive 20 lumens of pure blue light when driven at maximum power. Due to the superior build quality and high specification of the EPILED chips, these 1W LEDs retain an excellent level of efficiency even at higher drive currents. 

Please kindly note that even 1W power LEDs should be mounted onto an aluminium or copper heat sink with a thermal glue/compound between the rear LED and the heat sink surface. This thermal transfer is crucial to achieve optimal efficiency, performance and complete lifespan. As over-heating can cause a drop in light output active fan cooling is highly recommended particularly at higher drive currents.  

For convenience the general electrical and optical characteristics are listed below. For full manufacturers specification please consult the datasheet provided here.
