3W Super Cool White LED (Bridgelux 15000-25000k) on PCB
3W Super Cool White (15-25k LED) on 20mm PCB.
This premium LED uses a 45 Mil Bridgelux BXCE chip giving a very cool white light (15000-25000k) with a focus of power towards the bluer/violet wavelengths. All our LEDs come with a 120 degree lens fitted as standard.
Very popular for use in reef aquaria, vegetative horticultural lighting and automotive lighting, this powerful LED boasts an impressive 240 lumens when driven at maximum power. However 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.
