We Offer a wide range of B22 spiral compact fluorescent bulbs (CFLs), also known as Bayonet Cap (BC) or B22d bulbs, feature a 22mm two-pin bayonet base commonly used in the UK, Australia, and other regions. These energy-efficient bulbs use a spiral or helix design to pack a long fluorescent tube into a compact form, offering up to 80% energy savings compared to incandescent bulbs while delivering similar brightness.
