Are the SK636, SK638, and 636V2 UL listed?

Our lights (SK636, SK638, and 636V2) uses UL listed AC adapter to charge the battery. Therefore, it doesn't need UL for the main light.

We use an UL approved AC adaptor to charge the battery pre-installed in the light. So there is no risk of AC electrical shock when handling the light. Therefore no need to pass any standard.

They are designed for residential use only, not for commercial or industrial use.

For commercial or industrial use emergency light, the light has to be permanently hard wired by electrician to the grid, not by DIYer.

The lights for commercial and industrial use have to be UL listed because the lights are directly wired to AC electricity. Therefore there is a risk of electrical shock, hence they have to pass UL standard.
