Questions about this item

How long will the nickel-cadmium battery last before it needs replacing?

The 4 Ah nickel-cadmium battery provides 3.3 hours of emergency illumination; typical service life is several years depending on cycle count and ambient temperature.

What limits continuous operation at the 122 °F maximum operating temperature?

At 122 °F the driver’s thermal protection will reduce output or shut down to protect the internal components and battery.

How much heat and power does the 4 W driver draw when running all day?

It draws 0.07 A at 120/277 V AC, so steady-state power is low and heat output is minimal for a 4 W LED load.
