STEDI ST4K-60 LED Light Bar
Performance That Lets You Turn the Sun Back On
The STEDI ST4K-60 LED Light Bar is engineered for drivers who demand exceptional long-range illumination and a broad, powerful beam. Featuring 60 premium OSRAM OSLON LEDs, the ST4K-60 combines high luminous output with precision optics to deliver outstanding visibility when you need it most.
Its 8 Flood + 44 Spot + 8 Flood reflector configuration produces a wide 50° flood beam combined with a tightly focused 5.8° spot beam, reaching an impressive 1 lux at up to 810 metres.
The 5700K Crystal White colour temperature provides excellent clarity and definition, while the high-quality optical system helps deliver a crisp, controlled beam pattern.
STEDI's Pure-Drive™ circuit design directs up to 97% of input power to the LEDs, helping maximise lighting performance and efficiency.
