High quality CSP 1860 LED upgrade for Marchal type bulbs with a double contact BA21D bulb base. With integral heatsink. Accepts 5 to 9V input voltage - optimised for 6V, positive and negative earth systems. High and low beam - 1600 Lumen high beam, 1600 Lumen low beam - with a soft beam pattern. In testing, much brighter (LUX measurement at fixed distance) than B5912 (45/40W) with a classic warm white light.
The LED layout is designed to match the original Marchal filament layout including low beam filament shield. The lamp produces a good high and low beam pattern - with the dip pattern governed by the lamp lens. Very low current draw - over 75% less than incandescent and halogen bulbs so great for low powered, vintage electrical systems. 4300K classic white colour temperature.
This bulb is a great LED alternative to a number of 6V bulbs including B5911B and B5912B. Made from aviation grade aluminium. These bulbs don't have an integral lens. Please see part numbers BA21DLED-H25YL and BA21DLED-H30L for LED upgrade lamps with integral lenses suitable for 6V systems. 67mm total bulb height, 12 x 25mm LED section. 21mm diameter, 3 pin bayonet cap.
