10W Royal Blue LED (440-450nm EPILED)
10 Watt High Power Royal Blue LED COB on aluminium back plate. This high quality LED uses a 9 x 42 Mil EPILED brand name chips, producing an intense royal blue light 120° beam, with a wavelength peaking between 440-450nm.
Popular for use in aquariums LED light (particularly marine set ups and for creating moonlight effects), vegetative grow lights and stage lighting. This versatile and powerful LED produces an impressive 180 lumens of pure blue light when driven at maximum power. However due to high specification of the 9 x 42mil EPILED chips these COB LEDs retains a high level of efficiency even at maximum driver currents.
Please kindly note that all high power LEDs must be mounted onto an aluminium or copper heat sink with a thermal glue/compound between the rear LED 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.
