Hazardous location LED Flood Lights

Hazardous location LED
Flood Lights
PRODUCT DESCRIPTION
With UL Class I, Zone 1 and Type
4X ratings, the EF1A series can be
used in hazardous locations, making
it well-suited to handle applications in
oil & gas industries, water treatment,
chemical plants, painting booths
and more. This design also allows
for increased mounting versatility
with mounting options including
adjustable, fixed angle, or no mounting
bracket. And with major international
certifications, EF1A can even be used
in applications worldwide.
