Low-Profile Blue Strobe Light

The Federal Signal LP3P-120B is a pipe-mounted warning beacon built for industrial and commercial safety applications. Its blue polycarbonate dome produces a high-intensity strobe visible across hazardous zones or outdoor perimeters. The IP66 and NEMA 4X rated housing withstands dust, water jets and corrosive atmospheres. Installers working on 120 V AC systems will find the half-inch NPT base a direct fit for standard conduit.

Thermal and Electrical Performance

Operating from -31 to 150 degrees F, the unit maintains output without active cooling or audible noise. A 0.10 A draw at 120 V AC keeps power consumption minimal on shared circuits. The strobe tube flashes 80 times per minute at 2.2 joules, delivering 175,000 candle power for the rated 7,000 hour lamp life. No moving parts mean silent operation in noise-sensitive environments.

Mounting and Lens Benefits

The screw-on polycarbonate dome allows quick lamp replacement without tools or housing removal. A 1/2 inch NPT pipe mount secures the light to rigid conduit, eliminating the need for separate brackets. Polycarbonate construction resists impact and UV degradation better than glass or acrylic alternatives. The wire-lead power input simplifies termination inside junction boxes or control panels.

Questions about this item

How do I install the LP3P-120B on a 1/2 in NPT pipe, and what step do people often miss?

Thread the base onto the 1/2 in NPT pipe and tighten the set screw; the step often missed is fully seating the screw-on polycarbonate dome so the IP66 seal engages.

What maintenance will this strobe need and when should I replace the tube?

Plan to replace the strobe tube after roughly 7,000 hours of operation; wipe the polycarbonate lens with mild soap and water if dirt reduces output.

What limit appears first when the light runs continuously in hot conditions?

The 150 °F maximum operating temperature is the first limit reached under sustained use; above it the electronics and lens can degrade.
