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.
