All Bulbs - Yellow premium 6, 12 & 24V LED Head and Spot lamp - BA21S (single contact) base

Yellow premium 6, 12 & 24V LED Head and Spot lamp - BA21S (single contact) base

High quality 16 x Cree 2525 (with heatsink) LED upgrade for Marchal type head and spot bulbs with a SINGLE contact BA21S bulb base. Extremely flexible application - suitable for 6, 12 or 24V vehicles and compatible with either negative or positive earth systems. 1800 Lumen beam, with a soft beam pattern. Two rows of transverse LEDs each side, to recreate the transverse filament arrangement of original bulbs.

Very low current draw - over 75% less than incandescent and halogen bulbs so great for low powered, vintage electrical systems (800mA at 12V, 1.6A at 6V). 2500K yellow colour temperature.

This bulb is a great LED upgrade alternative to a number of 6 and 12V single filament bulbs including B5812Y and BT2423. Made from aviation grade aluminium. These bulbs don't have an integral lens so can be used in tripod type lamps.

Please see part numbers BA21LED-H30TR and BA21LED-H43TR for Warm White and bright White versions of this lamp. 67mm total bulb height, 12 x 25mm LED section. 21mm diameter, 3 pin bayonet cap.

Two designs shown in photos, either design maybe supplied depending on available stock.
