LED Emergency Lighting and Exit Signs from China
1 resources tagged with "Emergency Lighting"
Emergency lighting and exit signs are safety-regulated products, so sourcing them from China is as much a certification exercise as a manufacturing one. North American projects need UL924, while EU installations require EN 60598-2-22, and reputable factories now pair LED fixtures with LiFePO4 backup batteries for longer cycle life than older NiCd packs. Specifying the wrong standard or accepting an uncertified battery pack is the fastest way to fail a building inspection.
Emergency lighting includes battery-backed luminaires and illuminated exit signs that activate on mains failure. The pitfall is sourcing a fixture that is 'UL-style' but not actually UL924 listed; for a code-compliant installation the listing and the battery duration rating must be real and documented.

FAQ
What certification do emergency lights need for the US?
UL924 is the standard for emergency lighting and exit signs in the United States and Canada. Confirm the factory holds a valid UL file number for the specific model, not just a generic claim, and that the battery meets the required runtime (typically 90 minutes).
Are LiFePO4 batteries better for emergency lighting?
LiFePO4 packs offer longer cycle life and better high-temperature stability than older chemistries, which matters in fixtures that sit charged for years. They add some unit cost but reduce field replacement and warranty failures.
