    Arrived today and well packed. I tried them and all three work. Very nice brightness and color, yet powered only with a current of 90 mA, I will see later for full power at 900mA. I tried to display the color spectrum with a cd-rom, But the camera does not manage to photograph them properly, but in real the whole spectrum is Well present. Good product.

    Everything works, bought 2 pcs of 50 watts for the light of a small plot with raspberry size of 30x15m. I took out an old satellite analog tuner, and there's a 30-volt power supply. I applied it to the radiator and pressed it down a little bit for the heatsink. After 10 minutes of operation (without thermoplastics) the radiator was heated approximately as a human body temperature of 30°-40° not hot. You don't have to turn the radiator on. The small radiator will need a fan because the diode itself was palpably hot about 60°. At a brightness of 50 watts of the full spectrum shines as 20-30 watts of normal. There is no super brightness at 50 watts, perhaps 100 watts of full spectrum will be super brightness. I'll see if it's not enough to buy more. The LED is made of quality, the thickness of the metal plate is 1mm-1.5mm Hard does n't bend. After a 10-minute test, the color wasn't lost, maybe other buyers in the reviews used it without radiators, so they burned out.

    It's working fine for now. I hope it will be durable and useful in the foil tent

    Действительно мощный светодиод. При подключении к 12в.защитный слой силикона стал из розового цвета оранжевый. Выгорел. Но спектр свечения остался тот же. Советую сразу ставить светодиод на радиатор.

    This is quite nice light. It shines really bright even at a bit more than half the power. To use it at the full potential you will need a current limiting driver (http://bit.ly/2vV29RT) and a decent heatsing: http://bit.ly/2vUJPs7

    I ordered two of these in 10 Watt - another in 50 Watt a few days later. The 10 Watt units arrived today - I hooked one up for a second - it's brighter than a $30 9" grow LED panel I bought last year. Considerably brighter. It also gets pretty hot pretty quick - and having some experience in components - I'll be setting up a heat sink for it prior to putting it in use. I've uploaded a picture of the heat sink I intend to use - salvaged from an old PC mainboard. I expect the 50 Watt unit will require a fan, and intend to use an old CPU cooler with that. Amazing how far LED tech has come. Note - that's a 1/2" box wrench in the picture for size comparison.

    Package delivered w/o damage. working perfectly. Next time I try 30w LED. power @ 11V & 0.9 A is 7.93 W (see photo)

    top price performance ratios As always enthusiastic all around only operate with heatsink and a lins is also attached (with 60° aperture angle for plants!) best still works a water cooling... but Banggood.com has everything on offer

    сделана очень аккуратно с любовью гладко отполированные теплоотводы и прозрачные линзы

    Plants really love the spectrum of these LEDs. Image is a fittonia plant growing on the desk under only one 10W LED. Leaves are crowded together, eating every foton :)
