LED rechargeable emergency light bulb, the general effect on the current actual situation, and other products is not much different, as long as it can to complete the function of other products can Completed. The biggest drawback is that you (if you buy a poor quality, very easy to bad, and even the famous brand not mean that the quality is good , Just aftermarket will be better than that). Lighting effects are relatively better, its lighter light LED light-emitting characteristics of the decision, it should be slightly lighter one These, of course, which is properly designed under the premise. Meanwhile, another important feature is the long luminous time, its power slightly smaller, of course, the conditions The same. In addition, your purchase will be heard lobbying its addition to the two main characteristics: First, the energy-saving; Second, fast response (bright fast); So-called energy saving, in fact, in the emergency lamp is not embody, as the UPS power supply, and only in the case of changing the circuit will reduce the leakage current, the solid It is energy saving. Only under the same brightness requirements, LED lamp power, life time will be slightly longer, but the difference is not very large. Another A fast response, is supplying current to the light emitting time period can be faster than the ordinary light, six to ten nanoseconds, if not special requirements, this feature is in reality very Difficult displayed.
