3W Daylight White LED (Bridgelux 5500-6000k)
3W Daylight White High Luminance LED for reflow solder to printed circuit board (PCB). This premium LED uses a 45 Mil Bridgelux BXCE chip emitting a natural white light (5500- 6000k). This LED as comes with a 120 degree lens fitted as standard. Please note these LEDs are intended for mounting onto a PCB (printed circuit board) for correct operation. If you need to site these LED individually or need flexibility in your array, we recommend viewing our LEDs that come pre-mounted onto aluminium star PCBs here.
Popular for use in photographic, domestic and therapeutic lighting, this versatile and powerful 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 US designed Bridgelux chips these 3W LEDs retain 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/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 manufacturers specification please consult the datasheet provided here.
