1W Deep Red LED (EPILED 640-660nm)

1W Deep Red LED (EPILED 640-660nm)

£0.99

1 Watt EPILED deep red LED for reflow soldering to printed circuit boards. 

This premium 1W LED uses a 38 Mil EPILED chip achieving a powerful deep red 120° colour beam peaking between the ranges of 640-660nm.

Designed specifically to aid photosynthetic response in grow lights and planted aquariums, this versatile and powerful LED produces up to 20 lumens of deep red whilst retaining a high level of efficiency even at higher drive currents. 

As with all power LEDs any LED array will need adequate heat management for optimal performance, efficiency and lifespan. As such this component must be mounted onto an aluminium or copper heat sink with a thermal glue/compound between the rear of the PCB and the surface of the heat sink. Even for 1W models 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 need further information please feel free to contact us as any time and our UK staff will be happy to help. 

* Please kindly note that these LEDs are intended for mounting onto a PCB for correct operation and not directly to a heat sink. If you need to site these LED individually or directly onto a heat sink, please view our LEDs that come pre-mounted onto aluminium star PCBs here.
