1. Diecasted aluminium alloy shell with plastic-sprayed surface.
2. The transparent mark-plate can be chosen and matched to user's requirement.
3. Electronic luminescence board type, uses special piezoelectricity effect, under the normal, it hardly consume the fime it can
last several hours in the emergency meanwhile, need no maintenaince and reduce the operation cost use.
4. Under the normal power-supplying condition, the inner nickel-cadmium can recharge automatically, so that, the emergency
lamp will turn on automatically when the power lose because of accident or power failure.
5. Suitable for both steelpipe and cable wiring..
