Led bar 90W 620X53X60 mm/23.5" XMITTER Low ProThe Low Profile Prime bar is compact, with a height of only 53mm for universal fitment, in confined spaces. This low profile LED bar uses Prime Drive technology which manages heat levels to extend the life of the LEDs.The ETM monitors the heat emitted by the LEDs and uses a pulse-width modulation IC to maintain safe operating temperatures and extend the life of the LEDs up to 50,000 hours.The Low Profile Xmitter Xtreme uses built-in PWM (Pulse Width Modulation) dimming circuitry to manage heat levels. PWM works by flashing the LED at a rate faster than the human eye can detect, reducing the LED's run time, while still providing 100% light output.Features: LEDs: 5W for 18 LEDs housing material: Aluminum light color temperature: 6000 Kelvin voltage: 9-32V DC IP68 waterproof tested temperature: -40°C to +80°C Vibration Rating: 15.6 Grms lens material: Polycarbonate integrated electronic thermal management built-in PWM dimming circuit advanced heat sink design certifications: E-Mark ECE R112.01 Technical specifications: beam: 10° distance: 429 m raw lumens: 8874 lm power: 90W amperage: 7.5A size: 620X53X60mm/23.5"
