LED Light Is Explosion Proof

For hazardous or hostile environments, model EPL-MB-161M-100 is an explosion-proof light-emitting-diode (LED) light that provides 10,000 lumens illumination. It features a frame constructed of nonsparking aluminum and a Class 1, Division 1 approved 150-W round LED lamp head mounted within a square frame aluminum pedestal base. It is light in weight and includes an additional aluminum bracket with four magnetic feet—each with 200-lb gripping power—for mounting the lamp and bracket to almost any ferrous metallic surface. The EPL-MB-161M-100 explosion-proof lamp can be used as a standard pedestal light or a temporary mounted light for illuminating larger areas. The 16-in. LED lamp is adjustable; it can be moved through vertical adjustment within its bracket by loosening two thumbscrews on either side of the lamp head and positioning it as needed.
