LedEngin announced 5W Far Red LED for horticultural grow lights

Sep 8, 2009 LedEngin, Inc. announced the addition of Far Red products to its high power LED product portfolio for horticultural applications. The Far Red 740nm LED provides record radiometric power up to 400mW in a compact 4.4 mm x 4.4 mm package with exceptional radiant flux density for LED grow lights.

LedEngin Far Red LEDs add to the current portfolio of Red (635nm), Deep Red (660nm) and Blue (460nm) LEDs for horticultural grow lights. The Far Red wavelength simulates seasonal effects and the onset of sunrise/sunset to prolong perceived daylight. This product completes the family of desired wavelengths in the plant absorption spectrum of light believed to enhance plant growth. LED grow lights allow customers to optimize the light to promote accelerated and predictable plant growth while realizing high energy efficiency compared to traditional horticulture lamp sources.

The robust packaging allows the LED to meet JEDEC Level 1 Moisture Sensitivity Levels for unlimited product floor life. The combination of high power density and high moisture resistance will enable the development of new horticulture fixtures which capitalize on the energy efficiency, robustness, and long lasting benefits of LEDs.

Immediate product availability of 5W LEDs with other configurations possible.
