Output quickly deteriorates. Other options available
on December 11, 2008
We purchased two units. Our kids love reading in bed, and they sometimes prefer using a flashlight rather than a reading lamp. Plus, there are all the other good reasons to have dependable emergency lights.
These units provided a moderate amount of light - a bit dimmer than typical 2 D cell flashlights. And, that was OK with me.
However, the amount of time that the unit would provide light quickly decreased. After just 5 or 6 uses, light output would last only 90 seconds or so, and the brightness level also decreased. It soon became too much hassle to try to sustain light output for more than a few minutes - the frequent cranking was annoying, and every use further decreased battery life and light output.
The light's concept is appealing - but the implementation is poor. The light might be OK for a few uses, but based on the quick deterioration of performance I would not feel very confident that it would dependably work when needed and as long as needed in an emergency. Maybe the best use is in a car when you are unlikely to need light for a long period.
Another OPTION, if also less than perfect: Amazon is selling slow self-discharge rechargeable NiMH batteries. These cells retain 85% of their charge level after 1 year of sitting on a shelf. So, there is the option of buying Sanyo Eneloop (or similar) AA NiMH Pre-Charged Rechargeable Batteries and adding them to a few quality flashlights. Recharge once per year, and you have viable emergency lights, and perhaps keep some extra batteries around. These long shelf-life batteries are selling like hotcakes to photo enthusiasts, because you can immediately shoot photos even if your camera has been stored for 12 days or 12 months.
