LED Dynamo TorchOrder code: SC92018
Made especially for us from clear plastic so that the ’workings’ are easily seen, this easy to charge dynamo torch has three LEDs for a bright usable output. Charging is accomplished by repeatedly squeezing and releasing the handle which both powers the LEDs and charges an internal storage cell. In trials we have charged the storage cell for just a few minutes and found the LEDs were still glowing, albeit faintly, more than 24 hours later!
