3W Warm White LED (Bridgelux 2900-3200k)
3W Warm White Bridgelux LED for mounting to PCB (printed circuit board). This high luminance LED uses a 45 Mil Bridgelux BXCE Base chip that emits a warm white (2900-3200k) light with a focus of power towards the blue wavelengths. As with all our LEDs they come pre-mounted with a 120 degree lens as standard.
Popular for use in aquatic, horticultural and domestic lighting, this versatile and powerful LED produces an impressive 260 lumens of warm 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.
If you require further information, please feel free to contact us as any time and our UK staff will be happy to help.
* Please note these LEDs must be mounted to a printed circuit board for correct operation, If you need to site these directly to a heat sink, please view our LEDs that come pre-mounted onto aluminium star PCBs here.
