Supercapacitor Hand Crank Wind-Up Torches?

A few years ago you could buy Wind-up torches that had a capacitor rather than a rechargeable battery , Can you still buy these as i can't find them anywhere?

Thanks

Elder members of the family like them to keep in the draw as an emergency and i had a look in the " Spec me a torch " thread but i couldn't find any that were hand crank?

You used to be able to buy the LightStorm CL1 ultracapacitor LED torch above that never needed a Battery but i can't find them anywhere , IKEA do a ultracapacitor torch but it's a ridiculous shape , aimed at kids and is on the Dull side.

The above youtube video shows perfectly what the problem is with standard emergency torches if you leave them for a long time.

Thanks for the alternative suggestions but they want windup.

Well i can see why Super-capacitor torches never took off as they are crap , My neighbour has a couple from when he was a security guard and they are bright for several seconds after winding and then the Super-capacitor voltage drops off an they start to dim.
