Jansicotek C6-H4 H4 9003 LED headlight set 2 pcs 72W 7600LM 6000K

H4 9003 dual-beam LED kit

The Jansicotek C6-H4 is a set of two H4 (9003) dual-beam LED headlights built for cars, SUVs and RVs wanting a direct halogen replacement. Each bulb draws 36 W for a combined 72 W and emits 3,800 lm per unit, totalling 7,600 lm at a pure-white 6,000 K colour temperature. The all-in-one design needs no external driver and fits the factory socket on both driver and passenger sides.

Voltage range and beam limits

The units accept a wide DC input from 9 V to 36 V and maintain a steady 2.6 A draw at 12 V with built-in constant-current control and anti-interference circuitry. Forward voltage per bulb spans 9 V to 14.5 V, while the adjustable beam angle covers 61 to 120 degrees and the rated projection reaches 200 m. IP68 sealing protects against water and dust ingress in all weather conditions.

Output headroom and fitment boundary

At 7,600 lm the kit far exceeds a typical 1,000 lm halogen bulb and a common 3,000 lm LED alternative, giving strong headroom for night driving on unlit roads. The plug-and-play installation takes roughly 20 minutes on most vehicles, but cars with tight headlight housings or CAN-bus systems that reject the 2 W standby draw may need additional adapters not included in the box. Buyers who need a higher lumen count or a different colour temperature should look elsewhere.
