For example, railway tunnels and other places may require power off when they need to be repaired, and they will need to use emergency lights. Now, because of the promotion of energy conservation and emission reduction, LEDs are used in many ways, and because of the wet reasons, they need to use three. Anti-light. Like our company, there are several models of three emergency LED emergency lights: NFE9121 and NFE9178. These two LED emergency lights are very commonly used. The monthly shipments are very large. The emergency time for these two models is about 10 hours, which is completely enough for workers to overhaul, and their service life is also very long. They can use 100,000 hours. In general, where the three lights are used, the environment is not very good, so the workers do not need to replace the lamps often to damage the health of the construction.
