    What do the lighting guru's say .... Yay or Nay?

    [​IMG][​IMG][​IMG]At a Glance...
    •LED Grow Light to stimulate plant growth and keep them healthy when grown indoors.
    •Designed for maximum energy-efficiency to reduce wasted light, heat and costs.
    •Environmentally safe product with mercury-free bulbs.
    Manufacturer Specifications:
    •Main Function: LED Grow Light
    •Power Output: 15W
    •Power Voltage: 80 - 265V
    •Dimension: 310mm x 310mm x 38mm (L x W x D)
    •Expected Lifespan: 20,000 hours
    Product Notes:
    •Significantly quieter with no noisy fans, ballasts and chillers.
    • Lightweight with a flat base, this LED Grow Light can easily be hung or mounted directly to a flat ceiling, making this model easier for mounting in tighter spaces.
    • Individual LED's produce relatively small light cones, so they are clustered into arrays so the light cones overlap, increasing light intensity and coverage area, meaning you can get a larger coverage area from each light fixture.
    •No wasted energy or extra cooling equipment needed.
    •For use indoors or in greenhouses only. Not waterproof.

    Grow Light Panel
    Frequently Asked Questions:
    What are the frequencies of red light and blue light?
    Both red and blue light are part of the visible spectrum, this is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Red light has a wavelength of 620-750nm and a frequency of 400-484THz. Blue light has a wavelength of 450-495nm and a frequency of 606-668THz.
    Why is red light important for plants?
    The red region has a utilization peak around 660-670 nm for Chlorophyll A and around 635-645 nm for Chlorophyll B, depending on the source of information. Plants generally make good use of all red wavelengths except for ones much longer than 670 nm.
    Why is blue light important for plants?
    Photosynthesis works most fundamentally from red light and secondarily from blue light. However, many plants have some need for blue light for proper growth regulation and/or flowering and/or fruiting.


    +/- 300 lumens and about R400 - used for growing plants but can it be suitable for marines?

    By no means a guru - but I've had a quick squizz at these units before and my immediate reaction is no, not worthwhile at all.

    They use the piddly old 1w "superbright" LEDs which generally lose their spectrum quicky from what I've read. And secondly, the blurbs harps on about red light a lot, which I'm sure we all know is the exact opposite of what corals are adapted for. Red light gets absorbed very quickly by water, so most corals have evolved to make use of light closer to the blue end of the spectrum.

    never said it was cheap, but it might save you on electricity

    OK ... no more comments on this unit .... Looks like I must be a guinea pig and test this out... worse case scenario I end up having a very expensive ATS light......

    Unfortunately not and I'm like 300km's away from the seller so I'll just order and test it ... Fortunately I know the supplier so if not working out willjust return for a credit untillI need something else from him..... will post findings and pics once I get it .... Maybe in conjunction some 54W T5's might just make an awesome unit.....
