Incredibly Bright - Three rows combined with concave and multi-layer reflector. The 4 in round LED light fixture contains 68 high-intensity CREE chips and a new matrix reflector, plus a high-transmission lens! Emits bright 6000K white light and provides 15,000 lumens. UPGRADED DESIGN - Our round LED pods have a lifespan of about 50,000 hours with an IP68 waterproof, dustproof, quakeproof, anti-corrosion rating for harsh environments. Upgrade PC lens surface with high light transmission reduces optical loss! BETTER HEAT DISSIPATION - Black heavy-duty 6063 aluminum alloy housing with built-in oversized heat sink keeps the temperature down and allows the LEDs to run cooler and brighter. The sharp aluminum fan design helps dissipate heat faster and more efficiently. MOUNT IT YOUR WAY - The included adjustable U-type mounting bracket allows you to adjust the LED driving light to what you like, making it easy to change the direction of the light beam. The lamp can be slid after installing
