I gave you the names that the particular crank flashlight I have were sold under... LOL

The Illuminator

Wind 'N Go

Dynabrite

Notice that each one has a different description and within list different durations after one minute of cranking. It may not in fact be the same light. It looks like them though.

I tracked back the actual model I purchased... thank goodness for email invoices...

It's the Kaito TF-301, and though yellow in the picture, the one I have is sliver like the others.

Here's a link to the light on Kaito's site:

After checking out the company, and noting it's a Chinese conglomerate of electronic manufacturers, all of the lights listed above are probably basically the same model.
