Yellow LED (585-595nm EPILED) - 800mA
A yellow high luminance LED attached to a 19.8mm x 1.6mm star PCB. This high quality LED uses a 42 Mil EPILED chip, producing a powerful yellow 120° beam, with a wavelength peaking between 585-595nm.
Popular for use in automotive, horticultural and stage lighting, this versatile and powerful LED boasts an impressive 60 lumens of yellow light when driven at maximum power. Due to the superior build quality and high specification of the EPILED chips these 3W LEDs retain a good 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 used and the heat sink surface. This is crucial to attain optimal performance, efficiency and lifespan in any LED application. Active fan cooling is highly recommended particularly at higher drive currents.
For convenience the general electrical and optical characteristics are listed below. For full manufacturer's specification please consult the datasheet provided here.
