3W Warm White LED (2900-3200k)

3W Warm White LED (2900-3200k)

£1.49

3W Warm White Bridgelux LED attached to a 19.8mm x 1.6mm star PCB. This high quality LED uses a 45 Mil Bridgelux BXCE Base chip giving a warm white (2900-3200k) light with a focus of power towards the blue wavelengths. This LED comes with a 120 degree lens as standard. 

Popular for use in aquatic, horticultural and domestic lighting, this LED produces an impressive 260 lumens of cool white light when driven at maximum power.  Due to the superior build quality and high specification of the Bridgelux chips these 3W 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 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.
