YR-TL300 Series LED tunnel lights from Yaorong Technology are designed to offer precise symmetrical or asymmetrical photometric distribution for tunnel and underpass lighting. Designed to meet recommended luminance and illuminance requirements set by all national and international standards, YR-TL300 features a modular configuration that provides a complete and scalable wattage from 30W to 240W and light output from 3,300 to 26,400 delivered lumens. This scalability allows flexible combinations of light modules for various application needs. Constructed from die cast aluminum electrostatically sprayed with a polyester powder paint finish, the luminaire housing with integrated heat sink offers superior thermal management through heat dissipation and thermal conduction. The modular light engines utilize LUXEON Rebel LEDs that deliver industry-leading efficacy, lifetime and reliability. Precision designed optics provides optimized photometric performance and light distributions to avoid black-hole and flicker effect in either probeam or counterbeam orientation. The high performance Mean Well constant current driver an unparalleled level of efficiency and reliability with enhanced protection features including overcurrent, short-circuit, overvoltage and over-temperature protections. The optical assembly and driver compartment are hermetically sealed to provide IP65 ingress protection.
