Good flashlight more than a thousand, even thousands, of poor ten Few dollars or a few dollars. In fact, the torch above there are a lot of articles can be done. For example, take the high titanium alloy and magnetic induction. Low-end use Forming one package (ie, the integration of the battery compartment and the housing) so save a lot of costs, and the process is simple and modular development, mainly to do. Can be integrated with low-end LED torch the market. You can also do another flashlight diversified product line. Such as the emergency lights and other lighting can do.
