1W Bright Blue LED (EPILED 460-470nm)

1W Bright Blue LED (EPILED 460-470nm) -

1 Watt Bright Blue High Luminance LED for mounting to printed circuit board (PCB).

This high quality LED uses a 45 Mil EPILED brand name chip, producing a powerful bright blue light 120° beam, with a wavelength peaking at 460nm. 

This versatile and powerful LED produces an impressive 25 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. 

As with all high power LEDs this component must be mounted onto an aluminium or copper heat sink with a thermal glue/compound between the rear of the PCB. This is crucial to attain optimal performance, efficiency and lifespan in any LED applications.  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.

If you need further information please feel free to contact us as any time and our UK staff will be happy to help.

* Please kindly note that these LEDs are intended for mounting onto a PCB for correct operation and not directly to a heat sink. If you need to site these LED individually or directly onto a heat sink, please view our LEDs that come pre-mounted onto aluminium star PCBs here.
