OSRAM ULTRA LIFE H4 Car Bulb, 12 V 60/55 W, P43t Base
Up to four times longer life than a standard H4 halogen bulb.
The OSRAM ULTRA LIFE H4 halogen car bulb (64193ULT) runs on 12 V at 60/55 W with a P43t base, combining low and high beam in a single lamp. Supplied as a single bulb with 1650/1000 lm of luminous flux.
Durability rated up to 100,000 km
The filaments are rated at 700/3000 hours average life (Tc), which means far fewer replacements for daily drivers and cars running permanent daytime lights. OSRAM quotes up to 100,000 km based on 14,259 km a year with the lights on 60% of the time.
P43t base for low and high beam
The bulb carries ECE H4 homologation and fits the headlights of most 12 V passenger cars. The glass measures 17 mm in diameter with an overall length of 82 mm.
Silver cap for clear-glass headlights
The metallised tip looks clean behind a clear lens and stays discreet when the lights are off. Colour temperature is 3200 K, the familiar warm-white halogen tone.
