    These are very nice 100 watts LED light without external DC power supplies. Problem I ran into is the cooling. These lights are running very hot. The square ones are easy to cool down with a CPU heat sink and fan, but these are long rectangular. They are hard to find a adequate heat sink for them. I have not able to use them yet because of this heat sink problem.

    The light quality is, as clearly advertised, really better than other led emitters. The color rendering index (wharm light version) is so good that you can use this leds as light source for living room office or shop. The only thing that is not as advertised is the power of the led. The led rated as 100W, in the reality are only 60W (measured with professional equipement). This is not a big problem ! The lumen output is high, for the real power, but maybe you will need a bigger number of leds than

    it ok for use distance 2 m * 2 m it ok Bright. but Light can't use for long distance it very super Heat a lot. I open 220V for 1 min. it Heat very fast and can't touch any where. and hard to find heatsink to use with this item. You must use very big size heatsink.

    The power consumption of this seems to be a bit all over the place. Some times it's at 60W and some times it's at 110W. I currently use it as a growing light for my plants during the winter. I have to use an active heat sink though, with a fan, as it generates quite a lot of heat.

    After hooking this unit up to 240v it operated fine for about 45 seconds then began to flicker and dimmed to very low light.Checked solder connections and they were fine.Will be seeking replacement of this product as I believe it is a good product judging by finish.

    Muy buen producto y a muy buen precio. Para que funcione bien necesita un buen radiador. la calidad de la luz es muy buena pero cuando se hacen fotografías a alta velocidad aparecen bandas de apagado normal por la tecnología que utiliza.

    Светит, не греет, качество хорошее, на подложку не пробивает. Количество света вполне соответствует мощности. На глаз.

    Puts out an amazing amount of light (120 V) and very easy to mount to a heatsink. Takes a little bit of heat to solder wires to the pads due to the heat conduction of the Aluminum backing plate. Would suggest using heat tolerant wires...

    A lot better than LED that needs power supply. Just solder 220V wires onto it and plug in. Must use a fare size heat sink. Vey happy ordered more
