Long-life H7 halogen bulb with 1500 lm of standards-compliant light.
The OSRAM ULTRA LIFE H7 (64210ULT) is a 12 V, 55 W halogen headlight bulb with a PX26d base. It delivers 1500 lm at a colour temperature of 3200 K — the warm white light familiar from factory halogen headlights. Supplied as a single bulb.
Service life of up to 1100 hours
OSRAM rates the bulb at Tc 1100 h and B3 700 h, against Tc 550 h and B3 330 h for the same size in the ORIGINAL LINE series. A practical choice for cars where reaching the headlight housing is awkward and every replacement costs time.
PX26d base for standard H7 headlights
Measuring 12 mm in diameter and 59 mm in length, the bulb meets ECE requirements for the H7 category and drops straight into any H7-approved headlight without adapters. Nominal voltage is 12 V, with 58 W power input at the 13.2 V test voltage.
1500 lm at 3200 K
Luminous flux tolerance is ±10 %, keeping both headlights closely matched when the pair is replaced together. The warm white spectrum stays within standard halogen output, so no headlight readjustment is needed.
