3W Daylight White LED (Bridgelux 5500-6000k)
3W Daylight White High Luminance Industrial LED attached to a 20mm aluminium star PCB. This LED uses a 45 Mil Bridgelux BXCE chip giving a close representation of natural daylight at a colour temperature of 5500-6000k and a CRI value >70.
This premium component boasts an impressive 270 lumens when driven at full wattage. However, due to the superior build quality and high specification of the Bridgelux chips, this LED retains an excellent level of efficiency even at higher drive currents.
Please note that in order to attain optimal performance, efficiency and lifespan this component must be mounted onto an aluminium or copper heat sink with a thermal glue or compound between the rear of the PCB. 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
If you need further information please feel free to contact us at any time and our UK staff will be happy to help.
* Please note these LEDs are intended for mounting onto a PCB for correct operation and not directly to a heat sink. If you intend to mount your LEDs directly onto a heat sink, please view our LEDs that come pre-mounted onto aluminium star PCBs here.
