Strobe, 21 Joules, Explosion Proof

XB4

Description:

These high output (21 Joule) strobes have been designed
for use in potentially explosive atmospheres and harsh
environmental conditions. The marine grade alloy or stainless
steel enclosures are suitable for use offshore or onshore,
where light weight combined with corrosion resistance
and strength is required. Units can be painted to customer
specification and fitted with identification labels.
