The LED emitted a very bright and white light, without blue or green. It´s simple to connect the LED with a power supply because the solder pins are very long. It´s also very simple to fix the LED of a heat sink with 4 screws. Additional the LED is very cheap. Together with the glass optic (SKU 13569) an the smooth reflector (SKU 39963) the light beam ...

* Much easier to use (wiring and heatsinking) than 30 x 1W LED, 10 x 3W LED, or such.
* DX now has drivers to support, such as sku.42746.
* DX has a couple of reflectors to support, such as sku.39963.
* Emitters are spaced out for good heat distribution to the plate. * I had at least one string of LEDs that had a "dud" (see pictures).
* Value ... Read more
it works very nice for a piriod of time but the heat sink is very hot. i instal it in Place of 300w halogen lamp and it's look o.k. after 10-15 Hours of working well, the led start to blink and give Less bright . the heat sink was very hot. i have change the power suplay and it didn't change. i think it is important to assembly fan to cool the led. ...

High flux output - about as 40W circle flurescent tube. Only one LED can iluminate very well one room. It produces pure WHITE and no blue tint. Enough lumens to work with reduced power (I use instead 30W about 20W) and produce lot less heat and still iluminate one room perfectly. When you drive it at 2.0 Amps (30W) it will be very hot shortly. I used ... Read more
AAHHHAHAHA this LED is very good!
Develops only 15.5 v 23 watt with absorption of 1.5 A.
With a single LEThis LED can illuminate a room.
This LED spotlight can work with SKU 39963. For now, I have not found anything wrong.
Good LED The price is good only about $ 23.
With $ 23 you have a 30 watt LED as though you have 3 LED 10 watt 12 volt.

Very bright LED
Drill-Holes fit old Pentiom CPU-Cooler with 40mm fan
Works wirth many laptop power-supplies (e.g. 19V, 3A), only simple Current Source needs to be added (1 N-Channel Power MOSFET, 1 NPN Transistor, 2 Resistors) The given Current-Rating too high. Only use the LED with 1750mA max.!
Light-Output seems too optimistic. The Datasheet says ... Read more
