Main Advantage: AILEO led headlight bulb, Newest Korean 6pcs CSP LED chips (Double-sided 12pcs/bulb.H4Double-sided 24pcs/bulb) Producing 25000 lumens output per set,with output 12500lm per light for safety driving at night, 6000K xenon white, far more than the halogen lamp. Super long lifespan: 30,000hrs,90W Per set,the power of each lamp only 45W,greatly extend the serving life. Lamp low heat: far less than halogen lamp, greatly prolongs the service life of lamps and lanterns. Health and safety: no high voltage and large current startup, no circuit interference and electromagnetic radiation, Canbus, No Error, driver smaller, installation easier, plug and play. Good light beam pattern: with a narrow strip light of light emitting surface, 1:1 the halogen design, rather than other products circular surface emitting. All-in-one aluminum profile as heat conduction system, 360 degreea heat radiating. High speed mute fan (15000R/Min),high Air flow for faster cooling rate. Specification: Plug Type: Hi/Lo Beam: H4 Single Beam: H7, H11/H8/H9, 9005/HB3, 9006/HB4 , HIR2 Power(per set): 90W/set LED Quantity(each bulb): AILEO custom CSP chip Luminous Flux: 25000LM/set Operating Voltage: DC 9-30V Color Temperature: Pure White 6000K IP67 rated water and dust seal,over 50000hrs lifetime Beam Angle: 360 degree Material: Aviation 7041 aluminum profile Operating Temperature: -40-80 degree Celsius
