Pro Double Row 18.4 Inch 24 LED Light Bar - Part Number: LED3303-PRO-24L
The STEDI ST3303 Pro 18.4 inch is a double-row LED light bar carrying 24 CREE XLamp XP-L HI LEDs behind 32mm parabolic reflectors. STEDI positions the ST3303 as its high-performance double-row bar, built for big light volume and long beam throw on touring rigs, work utes and dedicated off-road vehicles.
A combined spread and spot beam lights the road edges and the distance ahead at the same time, which helps most on unlit highways, corrugated outback roads and in rain or dust.
The face plate is A360 cast alloy over an extruded aluminium heat sink, the lens is optical grade hard-coated Lexan, and the bar is rated IP68, submersible to 3m. A heavy-duty Smart Plug and Play wiring harness, which STEDI states is ADR compliant, comes in the box with a switch, fuse and relay, plus HB3 and H4 piggyback adaptors for a clean high-beam connection.
