We present the actual state of power and light quality of bulbs - we do not overestimate lumens (as it happens in cheap Chinese replacements). Technical specification: Model: H8 / H11 Power: max 70W per set Voltage: 12V Lumens: max 4000 per bulb Type LED: CSP 3570 Temp. Colour: max 6000K Cooling: active (windmill on Japanese bearings) Housing: Aluminum Alloy Lifespan: max 30 000 hours Approval: No Characteristics: - shape and size corresponding to standard bulb - easy installation without modification - includes CANBUS system (however, it can cause an error in cars with sensitive computer *work in about 80-90% of vehicles) - attractive value for money - powerful, efficient CSP diodes - copper heat dissipation core - cooling fan with Japanese bearings - small size for easy installation - aluminium housing The aluminum, copper plate and temperature discharge fan used are sufficient for effective cooling of retrofit. The size of the retrofit embedding allows installation in the original adapters!
