B15 is the small bayonet cap, the compact counterpart to the standard B22. It appears in bedside lamps, compact decorative fittings, and fixtures where the smaller bayonet connection suits the scale of the fitting.
Dulora's B15 range covers candle (C35) and fancy round (G45) forms in Warm White 2700K and Extra Warm 2200K with CRI 90+ across the range. All dimmable models work with a quality LED-rated dimmer.
Before ordering, confirm the fitting is B15 (15mm) rather than B22 (22mm). The push-and-twist bayonet action is the same for both, but the diameter is different and the two aren't interchangeable. For the B22 range, see B22 Bulbs. For the E14 screw equivalent, see E14 Bulbs.

B15 Bulbs: The Smaller Bayonet for Compact Fittings
How do I confirm whether my fitting is B15 or B22?
B15 has a 15mm diameter cap with two bayonet pins. B22 has a 22mm diameter cap with the same pin configuration at larger scale. Remove the existing bulb and measure the cap diameter, or check the markings on the bulb base.
The bayonet action (push and twist) is identical for both sizes. Only the diameter differs.
What forms are available in B15?
Candle (C35) and fancy round (G45) in Warm White 2700K and Extra Warm 2200K. For GLS and larger forms, B22 is the standard bayonet base.
