803506382 XCMG GR2605 motor grader work light

The XCMG GR2605 grader 803506382 work light is the core integrated lighting component for nighttime and low-visibility operations. It is manufactured in strict accordance with XCMG’s original design standards, GB 3836 series explosion-proof standards, GB/T 25684.8 grader safety requirements, and ISO 3449 FOPS falling object protection specifications. It is specially customized for the lighting needs of the GR2605 grader’s working device and cab, and is perfectly adapted to extreme scenarios such as highway construction and maintenance, airport runway grading, open-pit mine stripping, and large-scale water conservancy earthwork filling, which involve high dust, gravel impact, frequent rain and fog, and continuous day and night operations. Serving as the operator’s “nighttime work eye,” it combines multiple functions such as high-brightness focusing, wide-angle floodlighting, explosion-proof and anti-glare, vibration resistance and wear resistance. It effectively covers the blade working area, the sides of the machine body and a range of 30-50 meters behind, solving the problem of poor visibility during nighttime construction. At the same time, it resists mechanical impact and dust corrosion in the working environment. It is a high-quality original factory replacement assembly for GR2605 grader work lights that have suffered light source attenuation, shell damage, seal failure, or drive failure, eliminating the need to purchase and assemble parts piece by piece.

This work light is equipped with a high-power KERI LED chip, with a rated power of 50W, a luminous efficacy of up to 120lm/W, a luminous flux of ≥6000 lumens, a color rendering index Ra≥75, and a pure white light (6000K) illumination effect close to natural light. It provides uniform illuminance without glare, and at a test distance of 3 meters, the illuminance is ≥5200Lux, accurately illuminating details on the work surface and reducing visual fatigue and operational errors. It adopts a dual-mode light distribution design with focused beam and floodlight. The focused beam mode has an illumination distance of ≥80 meters, suitable for long-distance work point lighting, while the floodlight mode has a coverage radius of ≥15 meters, suitable for large-area work area lighting. Mode switching can be achieved by rotating the lamp head, adapting to different work scenario needs. The LED light source has a theoretical lifespan of ≥100,000 hours, more than 10 times that of traditional halogen lamps. Combined with a potted constant current driver, it supports a wide voltage input of AC85-260V, perfectly adapting to voltage fluctuations in construction site power grids. It is flicker-free and free from electromagnetic interference, ensuring lighting stability while significantly reducing replacement frequency and maintenance costs.

The work lamp housing is made of 304 stainless steel through high-pressure die-casting, with an electrostatic powder coating for corrosion protection. It has a tensile strength ≥450MPa and a wear and corrosion resistance rating of WF2, resisting impacts from flying debris and acid/alkali environments. The transparent cover uses 10mm thick high borosilicate tempered glass with an impact resistance ≥7J. The metal-free protective mesh design reduces glare and shadows, improving lighting comfort. It adopts an explosion-proof structural design, with the housing verified by a 1MPa water pressure test. The welds are tight and the seal is reliable, with an explosion-proof rating of Ex d I Mb. It can operate safely in methane and coal dust explosive gas mixtures, fully meeting the safety requirements of high-risk work scenarios such as mines.

The lamp is equipped with original EPDM sealing gaskets and features a fully sealed structure design with an IP66 protection rating, completely preventing dust intrusion and strong water jet impact. It can still operate stably even in harsh working conditions such as water spray, humidity, and dust. The built-in aerospace-grade heat dissipation structure keeps the lamp body surface temperature ≤150℃, effectively controlling the LED junction temperature (≤60℃), delaying light decay and extending lifespan. It is equipped with a high-strength zinc alloy adjustable bracket, supporting stepless adjustment of ±180° horizontally and ±90° vertically. After adjustment, it will not shift or make abnormal noise under a peak vibration of 25g, meeting the lighting needs of different working angles.

The product’s mounting holes, bracket dimensions, and wiring harness interfaces are precisely matched 1:1 to the original pre-drilled positions on the XCMG GR2605 vehicle, with hole tolerances controlled within ±0.03mm. No welding, cutting, or modification of the vehicle body structure is required. Secured with original high-strength bolts, the entire assembly can be disassembled and installed by a single person. After installation, it perfectly fits the curved surface of the machine body, resulting in a low drag coefficient and no whistling noise during high-speed operation. The wiring harness uses flame-retardant, wear-resistant cables with waterproof connectors, allowing direct connection to the original electrical system without additional wiring modifications. The wiring cavity design facilitates parallel operation and is compatible with multi-lamp lighting.

This work light assembly has passed multiple authoritative tests and certifications: GB 3836.1-2010 General Requirements for Explosion-proof Electrical Equipment, GB/T 25684.8 Safety Standard for Grader Lighting, IP66 protection rating certification; 500-hour salt spray + UV aging test, with no rust on the casing and no seal failure; 100,000-cycle vibration fatigue test, with no loosening of the structure and no damage to the light source; wide temperature environment test from -40℃ to 80℃, with normal start-up and no performance degradation; the LED light source has passed the LM-80 luminous flux maintenance report certification, with light decay ≤3%/5000 hours.
