I own both the Garrity Power Lite and the ILLUMINATOR wind-up flashlights. They have the same basic design, but with the following differences:

1. Size: The Illuminator is about the size of a man's electric shaver. It is easier to hold and to crank. The Garrity is bulkier, mainly because of the extra plastic lenses in front. It is also less comfortable to hold because rubber grips on the sides are shorter (see my Customer Image for size comparison)

2. Ease of Cranking: The Illuminator's handle takes very little effort to crank. However, you need to turn it virgorously (2-3 turns per second) in order to charge up the battery. The Garrity's cranking presents more resistence and is noisier. But the good news is that you only need to turn it at around one turn per second to charge up the battery.

3. Light Output: Both flashlights use 3 white LEDs, and have the option to turn on either one or all three. As far as I can tell, the LEDs are identical. The main differnce is that the Illuminator's light output is diffused, while the Garrity added three plastic lenses in front to produce a well-focused beam.

4. Light Duration: When fully charged up, the Illuminator gives out brighter light initially. However, its light dimmed down within a few minutes. After ten minutes, the light becomes barely visible (see my Customer Image above). The Garrity, on the other hand, produces fairly consistent light output for at least one hour!

Based on longer light duration, I would recommend the Garrity over the Illuminator. The Garrity is also cheaper when you order it with free super-saver shipping. (Be carefull when ordering The Illuminator, because some places offer the flashlight for $8-10, but charge another $8 in shipping!)

[The following Info for geeks only]:
Why does the Garrity produce much longer light duration than the Illuminator?

The Illuminator uses one 3.6V Lithium-ion rechargeable button cell (capacity unknown, probably around 30mAh). The Garrity uses 3x 1.25V NiMH cells rated at 80mAh. In my opinion as an electrical engineer, the NiMH design is much better because:

1. Each white LED needs about 20-40mA at 3.6V to produce sufficient light output. Three NiMH cells provide a consistent 3.75V throughout most of the discharge period. The Li-ion cell may provide up to 4V when fully charged, but its voltage drops quickly during discharge to 3.6V and below. This explains why the Illuminator produces a brighter light initially, but dims down much faster.

2. NiMH cells are more robust and can withstand over-charging better than Lithium-ion cells can. Think about it: there are chargers that can fully charge up NiMH cells in 15 minutes (that is, charging at 4X), but there are no chargers that can do Li-ion cells in less than one hour. In this case, since you can charge up the battery in one minute and then use it for up to one hour, that means the battery is being charged at 60X! This kind of abuse is not recommended even for NiMH, and it can be murderous for Lithium-ion rechargeable batteries.

Warning: Don't crank the handle virgorously when you have just the middle LED turned on. This is because the voltage across three NiMH cells can be as high as 4.5V when being charged. At this voltage, excessive current can flow through the LED and burn it out - as I have found out for myself. Luckily I was able to replace the middle one with an ultra-bright greeen LED. (It looks really cool, too.)

Please check out my review on Duracell Crank Light 3 in 1, 3 LED Flashlight, Radio, Charger. I feel it is even better designed than the Garrity.

Look what I just discovered today: a user by the name "Tea Lover" ripped off my customer images for Duracell Crank Light and uploaded here as his own. Some people just have no shame! 4 stars

I purchased this flashlight for emergencies. Haven't had one yet but it's seen a lot of causual use. It's great not having to worry about changing batteries. Turning the crank is quite easy. You get many minutes of light after ten or so seconds of cranking. Also, if the flashlight is turned off after cranking it holds a charge for quite a while.

I liked it so much that I bought a second one, which now has a slightly different design. Unlike some reviewers, I prefer the new design. The crank is even easier to turn. When you first press the on button the 3 leds come on as before, but now the second click of the on button reduces it to one led, while the third click turns it back off. The new "one led" option allows the light to stay on longer, for the same amount of crankng. It is good for times when you don't need a bright light.

The feel of the on and off button in the new design is a positive click; the first version felt mushy to me. The crank locks into place in with a more positive click. The crank has been shaped so that when it is locked into place the grip of the flashlight is more contoured and fits into my hand better.

The old design does put out a whiter light than the new design, but when I tried both lights on the same text I found that I could read better with new design. Also, when looking at something at a distance I find the pattern of light thrown out by the new design to be more even. 5 stars

This past Wednesday, the Southern Tier of New York State and Northern PA experienced major flooding, the worst this area has ever seen. We were one of the lucky ones. Our home sustained absolutely no damage, but we were without electricity for over 3 days. My husband just got this flashlight as a birthday present the Saturday before the floods. This proved to be very handy. The light is bright and it illuminates for quite a distance. Also, the LED light is truer for color. When our other rechargables were used up, this one was still going strong. I plan on buying several more, one for each vehicle and three more for the house. I will never be without it. 5 stars

Based on the reviews of this flashlight, I believe this is probably a very good value. However, on the one I received, the crank mechanism broke after testing it a couple of times. Other than that, it appears to be well designed and I might even buy another one and see if I have better luck. All of the good reviews can't be wrong. I just thought my experience was worth documenting.

I am new to the crank light system so I bought one of these to see what it was
like. I liked it so much that I sent for three more.

The design has been changed slightly, I do not like it as much, I took one star away for that.

So, I like the first design VERY MUCH! and if you never knew
the first design you probably will be VERY happy getting this light.
Even if it is a bit clunky.

Okay okay... It could be 5 stars...

How wonderful to pick up a flash light and not worry about
the batteries being low or dead. And not having to collect old
batteries to "dispose of properly" 4 stars
