GY A60 B22 bayonet LED bulb is rated to the new UK Class-C standard. Using the latest technology, it delivers 1521LM at just 9.5W—while a 13W F-class bulb only reaches 1500LM, offering higher brightness with lower power consumption. It operates on 220-240V AC with instant, flicker-free, glare-free illumination and better eye protection. With CRI over 80, colours appear more vivid than products below 80. Featuring a standard B22 bayonet socket for easy installation, it has a 30,000-hour lifespan, reducing usage and overall replacement costs.
