3W Ultraviolet UV LED (380-390nm EPILED)

3W Ultraviolet UV LED (380-390nm EPILED) -

3W Ultraviolet UV High Power LED attached to a 19.8mm x 1.6mm star PCB. This high specification industrial LED uses a 45 Mil EPILED brand name chip, producing a powerful Ultraviolet light passed through a 120° non-degrading silica lens. Please kindly note that this product produces largely invisible ultraviolet light. Please note, if you require a visible violet LED please consider our Violet 410-420nm product. 

Popular for use in aquatic, horticultural and commercial LED lighting, this versatile and powerful LED produces up to 190mw radiation flux when driven at maximum power, yet retains a high level of efficiency even at higher 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 manufacturers specification please consult the datasheet provided here.
