Led Emergency Lights

The efficiency of emergency LED lights is defined according to the relation between the light intensity emitted and the electrical current that produce this radiation. The color of LED lights is usually red, green, and yellow-orange those have been standardized by the manufacturers depending on the radiation frequency. However, in case of emergency LED lights, this radiation is not visible, which gives it the color of standard lights used in households.

The only drawback of emergency LED lights is that batteries used in these provide power for a limited duration and need to be recharged, which may not be possible if the power remains unavailable for more than a day. It is better to purchase an emergency LED light that can be connected externally to a car or truck battery.
