Santa Clara, CA - August 27, 2009. LedEngin, Inc. today 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.
It's official. Ledengin is throwing its hat into the horticultural lighting ring. Looks like the 660's are going to be a permanent catalog offering. They're also real proud of the 40-watt whites they've come out with. Too bad this is just a 5 watter.

ledtime: check out the Mean Well PLN 60 series. Their 12V driver will push 4 red / deep red 15 watters beautifully @ 10.5-11V range.

You need their 15V driver for ledengin 15W blues. You can run 3 hard (18 watts) ea.) or 4 easy. Neat, simple, easy. Hooks direct to the LEDs. CC and CV. All protected. Just mount your leds and connect. :thumbsup:
