  • Compare to Prosorce Ww 1/2 the price

    Good price, very bright lights. absolutely works! Solid, balanced build. Very impressed how fast plant is growing.
    Good starter grow light, experiment how close/ far the light is at best for plant. 6"-8". Do your research online and you will find this is the best price arround. I received this item in about ten days.
    Green is the most visible light on earth.
    These LED lights work for photosynthesis...
  • Bright & hot

    posted by Flyowynd

    Very bright, cannot be sure it achieves 3800 lumen but can be compared to 3 XT60 which produce 1000 lumen each.Work with 36V power supply which is better than some new cree array that requires 45V.
    Good to provide a lot of light in a small place but definitly not recommended for a flashlight.Better for outside lamp or to replace some bulb where you can find a proper power supply.
  • Fine LED

    Lots of light, cheap
    I measured 1.6A at 33V at initial power-up.Current quickly rises (with temperature) in case of constant voltage supply. It seems more balanced at constant current.My camera claims the LED colour temperature is 6550K.I don't know if you get more when you buy those at 2-3x cost. I can't measure the output power, so I can't prove if it is cheap due to being failed in the manufacturing light intensity test, or it is just cheap.My base plate is nice and flat.
    Works fine
  • nice 2100mA led driver

    posted by yrnkrn

    Cheap price and works well. Can easily drive five, six, seven, eight XM-L in series with 2300mA current. It can drive nine XM-L as well, but the current is lower at 2100mA which indicates this is just a bit too much.
    As usual, output wires are too thin for this current.
    Nice driver, buy it.
  • Absolutely ludicrous amount of light

    posted by jsnider

    Purchased with SKU 39974 and SKU 12834, together they make an absolutely ludicrous amount of light.
    Be warned, shield your eyes.
    Would make a great light over a work bench.
    I purchased this to experiment with replacing projector bulbs with cheaper, longer lasting units. Effectiveness will depend on the projector used, compact portable projectors are difficult as they have too small an area for catching light to use an unfocused light, SKU 12834 is the incorrect style of lens to focus the light beam.
    Unbelievable light output but cooling needs to be considered very carefully.
