Mechanically, this product (Cooper Lighting LED125 Mini Compact Folding LED Work Light) is very well-designed. It can be attached to most metallic surfaces using the three magnets on the back, or it can be hung using the two bungee cords. The light angle can be easily adjusted.

There are just two operating modes. First press on the power button turns on both LEDs. Second press leaves just one LED on. The third press turns off both. The two high-power LEDs are very bright. They provide much better illumination than other products (such as the Cooper Lighting 80-LED Work light) that use large number of low-power LEDs.

The main problem I have with this LED work light is that, like most cheaply designed LED flashlights, it has no power regulations at all. The LEDs are driven directly by the three AA batteries. Since each LED is just a diode, its current (and hence power consumption) is very sensitive to the battery voltage. See the "Input Power vs. Battery Voltage" chart I uploaded to 'Customer Image' section, and you'll see what I mean.

When driven by three fresh alkaline batteries, the two LEDs combined consume around 1A of current, or over 4 watts of power. At this rate, the AA alkaline batteries will be depleted quickly. The product description claims '4.5 hours' of runtime when using alkaline batteries. But this number is highly misleading, since the LED brightness drops as battery voltage decreases. So you probably can only get 10% of the initial brightness near the end of this rated runtime.

On the other hand, this LED light works well if you use rechargeable NiMH cells (such as the Sanyo eneloop AA batteries) in it. This is because the combined voltage of three NiMH cells remains relatively stable at 3.6V, so the two LEDs consume a more reasonable power of around 2W. Based on my energy calculation, I expect at least 4 hours of consistent illumination from a set of 2000mAh eneloop cells.

Bottom line: This LED work light is a battery hog when you use disposable alkaline batteries. It is a reasonable value only if you make use of rechargeable batteries.

I'd been looking for a small work light that would be more convenient that trying to juggle a flashlight and do what I'm trying to do. It needed to be battery powered and reasonably bright.

This Might-D-Light really met my needs. With the hinged design I can lay it down or stand it up to angle the light where I want it. It also has 3 magnets (reasonably strong) and a couple of intergated bungie cords. So there are many ways to mount it/place it. You can also turn on one or both of the LEDs.

The LEDs are pretty bright. Don't expect it to replace a halogen work light, but it's quite reasonable considering it's powered by 3 AA batteries.

I read about this work light in a couple of different magazines and it sounded like it would be a lot better than other lights I have. Not the case. It isn't near as bright as I had been led to believe, the magnets that attach it to ferrous surfaces aren't as strong as I had been led to believe, and the attached bungees keep coming off their storage points and getting in the way when you aren't using them. Overall, pretty average.

Honest reviews on Cooper Lighting LED125 Might-D-Light Mini Compact Folding LED Work

I do a lot of odd jobs that invariably see me working and crawling into small dark spaces or sometimes working late at night. This works very well when I need extra illumination but where it would be difficult to drag a halogen worklight with a long power cord with me. My main complaint is similar to another reviewers, there doesn't seem to be any power regulation circuit to the LEDs, so they tend to drain batteries very fast unless you use NiMh batteries, personally I'm gonna mail the company and request they alleviate this flaw even if it drives the light's cost up ten more dollars it would be worth the savings in batteries alone.

This is a handy light. I have used it many times in which a flashlight would have not been convenient.
