The EF1

The only light designed for diving, hazardous and marine industries.

There are approximately 4,000 types of gas and vapour that are inflammable and/or explosive in hazardous industries. The EF1 provides safe and uncompromising illumination for land and marine petroleum exploitation, petrochemical and chemical industries.

Explosion proofing
The EF1 is safe to use in Zone 1, Zone 2, and Type IIA, IIB, IIC, and T1-T5 Levels, as GB3836 rated, and indoor/outdoor operations (such as factories, stations, stadiums, railway tunnels, culverts) for electricity, smelting, railway, mine, port and civil construction industries.

Advanced Temperature Regulation (ATR) technology enables dynamically adjustment to output performance according to body temperature. EF1's explosion-proof class is IIC, with Level T5 highest surface temperature (100℃).

A 10mm-thick epoxy resin explosion-suppressive optical lens, combined with a 3mm thick aerospace grade aluminium alloy body (20% thicker than ordinary flashlights) makes it feel like a tank. Incredibly rugged and tough. A sliding control switch provides rapid and accurate one-hand brightness adjustment.
