Very reliable driver, i have been using a few of these at 800-900mA and they have never failed. It is a simple and convenient way to power medium power leds. The wires are a bit thin, short and poorly soldered to the PCB. Replacing the wires was a bit complicated due to their awkward position in the ... Read more
It is a very good controller. small easy to install and very effective for middle LEDs power flashlights. works well to 800mA. Regulator lanterns perfect for medium power LEDs you feed up 1000mah if you do not need low power mode. cables welds are not very good, as the cables may be too short. Regulator ... Read more
Cheap and compact regulator, able to drive any kind of LED requiring 1.25A. Voltage is maximum available, but since LEDs are primarily current-driven, if you solder it first to the LED before powering it, it won't fry it. Useful when one wants to connect many LEDs in series. Small enough it will fit ... Read more
Runs very well, the device is very small for its power. It doesn't need heat sinking and that's a plus. When I got it in the mail it was poorly packaged, the driver was with a C6 flashlight but was just freely moving around in the yellow envelope. because of the poor packaging the copper wrapped around ...

Small package and reasonable output. Used this in a custom flashlight build and worked fine. if your driving more than one led in series then the input voltage will need to be greater, max is 18v The output was not 1.25A when driving one led at 4.5v so to get the rated 1.25A current supply a higher input ...

Can be used to drive several emitters in series and gives best efficiency when the LED Vf is closely matched to the input voltage. Current output can be vared by changing the loop back resistor. As they come they give 1.2 amps with an R2. Fit an R12 to up the ouitput to about 1.8 amps, or an R27 to get ... Read more
-Constant current is better than constant voltage for sensitive components.
-Current didn't fluctuate much during a 5 minute run test.
-Useful even for non-flashlight purposes -Wires are thin but functional, swap them if it concerns you. -Use a suitable input voltage for the Vf of your component load.... Read more
This driver is just awesome ! :) works well with many emitters like Cree Q5 and so on ... it puts out around 1.2A. The only con here is the loose wires ... but it is very easy to replace them with new better ones so ... it isn't really a con ... :) If they will just add better wires ... it will be even ...

These are a great deal. I have a friend who regularly builds his own lights and recommended these to me. I actually bought them to power a laser torch, as these are supposed to be constant current drivers. From what I have heard people have used these drivers with no issues. awesome! nothing so far, ...

Another satisfied customer of this product. I'm using it with an 18650 Cell to power an xml led in a p60 reflector ( sku5937).
Fits perfectly in the pill and very easy to solder. Does not heat up almost at all after long use and produces no noise. Only con...if at all is the size of the leads. But did ... Read more
