Rust Resistant LED Bulb has ceramic heat sink designed for high insulation and quick heat dissipation. The Bulb is acid corrosion resistant, high temperature resistant, aging-resistant, radio resistant, rust and mildew resistant. The Bulb has applied voltage range from 150 to 285 vac, horizontal double shock structure, and 6 layers of protective film, high lumen efficiency, and low thermal resistance. The Bulb has constant current, precise ic control driver that remains unaffected by voltage fluctuation and has built-in lightning protection, surge prevention, over current and over voltage protection, making the lamp more stable for longer life span. The Bulb has poly-carbonate material mad structure and has integration of high polish mould, patented appearance design. The Bulb has insulation case to avoid the risk of electric shock, heat dissipation, and upper and lower convection holes design. The Bulb has good air duct structure with high heat conducting plastics ensuring rapid thermal processing reduction in rise of temperature thereby making sure the LED is more stable and secure. The Rust Resistant LED Bulb can be availed with dimmable option and has driver voltage range from 150 to 285 V, power requirement from 3 to 9 watts, lumen output from 180 to 720 lumens, colour temperature from 3000 K to 6000 K.
