This light uses a Li-Ion battery

Another possibility is that this this could have inadvertently been caused by one of the USB Boomer's clever features, its in-built battery protection. This light uses a Li-Ion battery and which if you are not going to be using it for extended periods of time is best left at 50 per cent charge to preserve the battery life. To help you knock it back to 50 per cent in these situations simply charge the light up to 100 per cent and hold the button down for five seconds which turns on the light and shuts it off when the battery runs down to 50 per cent.,led spotlight Although there are many types of lights available in the markets today, the distinctive qualities of the LED bulbs increase its demand and usage in the global market.,led lights One of the most basic devices that run on LED is a flashlight. Older models relied on a single bulb to produce the light needed to make one work. Clever,,Air max classic These are what hold the charge that is accumulated by the solar panel. The bulb is the icing on the cake when it comes to these lights. but possibly too clever if this is why it turns on when shoved in to your bag with a load of other commuter gubbins.,Led lamp Another advantage of these bulbs is that it lasts for a very long time and is quite strong compared to ordinary bulbs. These bulbs do not shatter as it is made of epoxy case.

On list price the Boomer stacks up pretty well against the competition, the Electron Backupz we reviewed recently being £34.99 list although it could be found for a lot less online – something which could also be said about the USB Boomer's non-rechargeable sibling which lists at £24.99 but can certainly be found for a lot less than that. The front Boomer USB is a couple of quid more than the rear, at £33.99. Given that these type of lights are so often discounted it is harder to judge them on value, although we would say that judged on their list price all of the USB rechargeable back up lights are pricey.,Led strip light The next most important part of a solar LED light is the battery. Some of these are common and can easily be replaced, but some are slightly more obscure and can therefore be costly to replace.
