Universal LED Emergency Drivers
Automatically match any AC LED tube — exclusively from Hoye. The HEI-V is the only AC LED tube emergency driver with automatic lamp matching: it detects and matches LED tubes from different vendors, with no calibration needed. Whichever tube brand is installed, it simply works.
One device supports all three battery chemistries — NiCd, NiMH and LiFePO4 — no separate driver version needed. The first emergency light in Hong Kong with LiFePO4: 8–10 year battery design life, more than double the 3–4 years typical of NiCd or NiMH.

Universal LED Emergency Drivers with Self-Test
Automatic self-test — exclusively from Hoye. The self-test versions automatically run the periodic function and duration tests required for battery-powered emergency escape lighting, to IEC 62034:2012, and indicate faults locally — without manual testing. FSD Circular Letter No. 5/2021 [PPA/104(A), 5th Revision] permits automatic testing devices for the required monthly and annual tests. Available for AC LED tubes and low-voltage DC LED lights.
