Classic White premium 12 & 24V LED Headlamp - SBC BA15D base

High performance CSP 1860 LED upgrade for SBC headlamp bulbs with the BA15D base. Integral aluminium heatsink. Accepts 11 to 60V input voltage - optimised for 12V, negative OR positive 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 B171 (36/36W).

The LED layout and inclusion of a low beam filament shield on this lamp means makes this a dipping bulb in the syle of some Marchal, Bosch and later British Pre-focus bulbs. Some early BA15D bulb designs did have special dipping filament arrangements - either a transverse 'V' filament next to an axial 'V' filament, or a hemispherical shield under the dipped beam filament - though these bulbs have not been available for many years.

In testing, this LED lamp produced a great high and low beam pattern with Lucas 'U' flute style lenses in particular and is the recommended BA15D 'no integral lens' LED lamp upgrade for early headlamps fitted with these lenses, with or without a Bi-flex bar. For 'Difusa' style lenses, we recommend the BA15DLED-H43 style LED, which imitates a twin (unshielded) filament bulb, or BA15DLED-H43L with the integral lens that produces great light output - regardless of reflector condition - and an excellent, defined dipping pattern

Very low current draw - over 75% less than incandescent and halogen bulbs so great for low powered, vintage electrical systems. 4300K classic, warm white colour temperature. This bulb is a great LED alternative to a number of 12 and 24V BA15D bulbs including B171B (12V 36/36W), B1248B (12V 45/35W) and B194 (24V 36/26W - not currently available). Body made from aviation grade aluminium. As noted above, these bulbs don't have an integral lens, so can be used in tripod type lamps. 60mm total bulb height. 25mm max heat sink diameter, 15mm cap diameter.
