Bars, bars, bars. Everyone seems to be making bars.

"Transcend Lighting, Inc. a horticultural LED lighting company based in New York City has released the Infinity Linear LED grow light. The 4-foot long LED grow light is said to be ideal for new installations in which fluorescent or metal halide lights were previously used. Transcend says that the LED grow light incorporates the company’s patent-pending phosphor technology that delivers an emission spectrum optimized for plant growth and production yield while being energy efficient. The IP66-rated product works from 110V-277V. It has a projected lifetime exceeding 65,000 hours and comes with a 5-year warranty.

The device emits over 115 umoles (a measure of the number of photons emitted) while consuming 58 watts making it both high power and efficient. The company says that multiple bars can be easily connected for gapless light without any wiring. Transcend asserts that 36 fixtures can be operated off a single plug at 277 volts and 12 fixtures at 110-120 volts. This many fixtures translates to up to 144 feet of consecutive light emitters.

The heat sink allows easy mounting, the company notes. No hooks or screws are needed to suspend the luminaire. The suspension kit just slides into the mounting channel, and the mounting clips are then snapped into place, the company revealed. Transcend claims it takes just seconds to mount to any ceiling, wall or shelf.

“We are bringing this product to market in response to customer frustration with installation complexity of existing LED products. The Infinity Linear LED light has been designed to ensure quick and easy installation – from the simple plug type wiring to the gapless snap together daisy-chaining system. Feedback from our customer base has been overwhelmingly positive,” Transcend Lighting CEO, Brian Bennett, commented.

The company exhibited the Infinity Linear LED light in San Francisco from July 23-24 during the Maximum Yield Indoor Gardening Expo."

Damn. I'll hassle him for something I can DIY. Technology rocks but that's a big markup.

Oh really, how perceptive of you Stevo. Not what I was referring to. Regardless, a professional company doing more than just stringing white cobs together based on gg's post, and addresses a directionality issue certain people chose to remain ignorant about as well.... deserves to be listed in this thread with the rest of the horticulture led manufacturers.

Especially with some rats here reporting his threads, probably people who rather continue to sell their veg lights and keep growers misinformed... in the dark.

As I advised you before there is no future in this this industry for people like you who have zero to add and renounced the authority of reason. Won't be able to compete with innovation from real horticulture lighting manufacturers, completely different league. Suffixing your posts with a hurt butt streak isn't going to change that reality.

Waiting for white + lots of added red growlights to get cheaper before jumping ship again.

Benefit of pure white diy over adding red is simplicity.
Can't really be bothered to add red myself.

In greenhouses things are a bit different since those lights are often going to be supplemental or extending the photoperoid in which case the sun is also providing light.
In that case the lights seem to be much more pure purple. Lots of red with a little blue.

Pure indoor seems to be more pinkish (more white)
May also have to do with the fact that it's easier to recognize if a plant is sick with less purplish light

There's also the problem that different coloured LEDs have different efficiencies and phosphor isn't exactly ideal for pure efficiency either. Because converting blue light to red/green/amber etc. brings inefficiencies.

Green leds are by far the least efficient compared to red and blue leds.
Green is beneficial, but if it can't be generated efficiently it is practically useless.
And in the case of greenhouses the sun is already providing all the other light spectrums so it's not necessary to add green light provided you only need relatively little of it.

As long as green LEDs lack behind in efficiency those horticultural lights won't carry them. (besides maybe a select few which carry very few green diodes)

http://www.ledsmagazine.com/articles/2011/04/rensselaer-researchers-boost-green-led-efficiency.html

Seems like there has been some innovation but I don't think it's already available to us.
Also converted green (blue+green phosphor) seems to be more efficient than green LEDs by a big margin. Even if it's less narrow band.

Any way, converted green will always be less efficient than the blue LEDs that shine through the phosphor.

It's nice for our eyes, but for plants green can't really compete with blue right now.

Timber grow lights offers any color of led on the DIY kits as long as Osram makes it I'm sure he could get it. I'd like to add red and far red to my cxb3590

Ya I'm stoked to have an ecosunlite with all cree 3070's and 6 of there pcb smd boards. Of mostly red and deep red but 2 435 blue and 2 3000k whites. Plus I have a 12 led far red attachment for my 8 cob diy that the Eco goes in the center of.

Should be a good grow. What was your GPW of your last cob only run?
