Pipe-Mount Narrow-Dome Strobe Lights
Lights meet NEMA 4X for protection from corrosion and washdowns.
Light intensity is measured in candlepower (cp), which indicates how bright a light appears at a distance. Common examples include a car’s taillights (50 cp), traffic signals (600 cp), headlights (15,000 cp), high beams (50,000 cp), and police car searchlights (150,000 cp).
