[Luminous Intensity]Single hole extra size reflective cup with model-7070 LED chips and latest developed optical lens, which luminous flux & valid irradiation distance 300% increasing, create SPOT BEAM pattern and make the round led offroad lights perform extremely bright lighting even in the daytime. [Higher Standards]4 inch round pod lights realize an IP67 rating, meaning that it is completely secure against dust and particulates, submerged the round light bar in 1.5 meters of water for more than 2 hours and it still runs normally. All led pods are burn-in and tested for waterproof, dustproof, rustproof and shockproof before leaving the factory. [Tough Construction]6063 aluminum shell maximizes surface area for optimal & rapid cooling. PC optical Lens, 304 stainless steel mounting, 90 degrees adjustable brackets serve for ample illumination angles. Durable materials to endure any harsh conditions, boost the lifespan over 50,000 hours. [Smart Upgrade]4″ round driving lights use EMC te
