Key Features & Benefits:
-
High-Intensity 120W Rotary Strobe System:Â Features a powerful motor that spins two parabolic mirrors, creating a dynamic, omni-directional warning pattern. This rotating flash is significantly brighter and more attention-grabbing than static lights.
-
Dual 45-Watt Quartz Strobe Tubes:Â Produces an incredibly intense, wide-angle flash. The dual-tube design ensures consistent, reliable output and provides built-in redundancy; if one tube fails, the other continues to operate.
-
All-Metal, Weather-Tight Housing:Â Constructed from durable die-cast aluminum with a corrosion-resistant finish, this light is built to withstand harsh environments, extreme temperatures, and the rigors of daily use. It is designed to be water-tight and dust-proof.
-
Universal Mounting & Compatibility:Â The low-profile “pancake” design allows for flexible installation on vehicle roofs, decks, or in a variety of lightbars. It is compatible with standard 12V DC vehicle electrical systems.
-
Multiple Flash Patterns:Â Operates with a dedicated SN200/SN400 series power supply (sold separately) to deliver selectable flash patterns, including single-flash, double-flash, and quad-flash modes for versatile warning scenarios.
-
Distinctive Clear Dome with Colored Inserts:Â The light is supplied with a clear polycarbonate dome for maximum light output. It includes a set of snap-in, interchangeable colored filters (typically Red, Blue, Amber, and Clear) for compliance with local ordinances and operational needs.
