LED Grow Light Review & Comparison

LED grow light review line up. This video compares some of the most popular LED grow lights in the hydroponics industry. This is one of the better comparisons out there.

The following LED grow lights are compared head to head. The Kessil H350 Magenta 90 watt, ProSource illuminator Jumbo 180 watt, California Light Works Solar Flare Full Cycle 200 watt and the Haight Solid State PP-800Rv2 180 watt.

The test is based around a 3 x 3 foot growing area composed of concentric squares of 3 x 3, 2 x 2, 1 x 1 and the center point.  PAR (photosynthetic active radiation) readings were taken at different points inside the squares with the LED grow light placed at different heights above the growing area. The PAR readings were taken with the lights set at 12, 18 and 24 inches above the plants respectively. LED Grow Light Review. PAR testing

PAR testing was chosen over lumen testing for this LED Grow Light Review. Lumen readings only measure the intensity of visible light. PAR testing measures the spectrum of light that is available to plants for photosynthesis. This gives a much better picture of the LED grow light’s effectiveness for actual growing.

The California Light Works unit did the best overall during this LED Grow Light Review. This light gave some of the highest PAR readings of the lights tested. That being said the ProSource and the Haight Solid State made up some ground at the higher distances above the plants. The surprise in this test was the Kessil unit which held it’s own against the competition on a watt to watt basis. At 90 watts the Kessil unit was the smallest light tested.

This information should prove helpful to you when you are ready to make the leap to LED grow lights. Please check out the different suppliers featured here to find the best options and prices for you.

    Prosource worldwide is the best light period, I have tested the lights
    except solid state crap, california light works won’t flower near as well
    as pro source,and California light don’t penetrate deep through canopy,
    spring pro source will be releasing all new grow technology revolutionizing
    the grow industry……. .

    Thanks for the video!

    Comparisons are always great to see

    Thank you very very much for this info. There are a lot of choices out
    there and from what I’m finding out is that there are a number of companies
    that sell junk led lights. With your information I feel far more confident
    in buying an led and not getting ripped off. Thanks

    for vegeative stage plant growth is an all blue light better than blue and
    red combined. what about using cool and warm white leds as theese have
    6400k colour tempreture same as fluorescent which people have used for
    years with great results. for flowering should you use all red or is red
    and blue better. are the uv and infrared leds safe to use on some grow
    lights? i dont like the idea of being exposed to the uv leds. do the red
    and blue led lights work for both veg and flowering?

    Whats the diffrence between these name brand expensive LED’s vs cheaper
    LED’s?

    you need a handheld spectrometer to compare wavelength, google search
    AI-MK350, spectrometer gave you all spectrum information.

    Nice job doing the analytical research! Can you share one thing more if
    possible? Do you know if any of these LED lighting fixtures cause any sort
    of interference in the area where they were installed? Some LED lights do
    cause household interferences (due to poor design/shielding), and for this
    reason, may not be good choices even if the light spectrum is better.

    ..question is though??

    Do you wanna compare your best against my Cree CXA COB DIY?

    You won´t find much better light source then that, blew my bought panels
    out of the water and cost much less + have no secondary lens in the way
    “stealing” valuable light either like some lights have and no glas sheet
    either for taht matter just photons raining down right onto plants.

    SolarFlare is a nice unit no doubt but it´s not for us poor that´s for sure
    and no matter how good it´s still not better then a DIY solution built on
    Cree´s finest.
