All Bulbs - High performance H4 P43t Bright White LED lamps set (PAIR)

High performance H4 P43t Bright White LED lamps set (PAIR)

High-quality LED upgrade (with built-in mini cooling fan) for H4 lamps with the P43T base. Set of two H4 bulbs.  Flexible application - accepts 9 to 32V input voltage so suitable for 12 or 24V vehicles. Two high-power LEDs on each side provide high and low beam function - specified at over 1800 Lumen high beam and 1800 Lumen low beam, giving over 3600 Lumen combined. In testing, 90% brighter (LUX measurement at a fixed distance) on low beam and over 100% brighter on high beam than B472 (60/55W) with a modern, bright white look. Low current draw - less than 50% of 60/55w halogen bulbs, so great for lower-powered electrical systems. 6000K clean bright, white colour temperature.

The latest plug-and-play upgrade for H4 bulbs - modern, powerful, high-performance lighting with reduced current consumption; Estimated lifespan significantly higher than conventional bulbs. The filament layout, including low beam filament shield, produces a good high and low beam pattern - with a clean cut-off and dip pattern observed in testing in a variety of 5 3/4 and 7" light units.

This bulb is a very powerful LED upgrade alternative for a number of halogen bulbs including B472 and B475. These bulbs don't have an integral lens so can be used in tripod-type lamps. Total bulb height including wiring/spade connections 80mm, 19 x 42mm LED section. Due to the high-performance nature of the bulb, cooling cannot be achieved with a solid, no moving parts heatsink, hence the incorporation of a cooling fan.
