Tronic Color Changing LED Bulb, 9W, B22 Pin Base

Our review

This Tronic bulb is a 9-watt LED with a B22 pin base that lets you change its colour output between warm white and daylight. That makes it a practical choice for rooms where the lighting needs shift through the day, such as a living room that feels cosy in the evening and brighter in the morning. It suits renters and homeowners who want one fitting to do two jobs without swapping bulbs. Before buying, confirm your fixture takes a B22 pin base rather than a screw fitting, since the two are not interchangeable. Also check that your switch or lamp setup suits a colour-changing bulb, as some rely on being toggled to switch modes. Compared with single-colour LEDs, it offers more flexibility for a similar running cost, though a plain warm white bulb may be simpler if you never change settings. Available on Sokonia.
