Tronic Square E27 LED Warm White 5W Bulb

Our review

This Tronic bulb is a 5-watt LED with a warm white light and a square shape, using the standard E27 screw base found on many indoor lamps and fixtures. At 5 watts it is a low-power option, so it tends to suit bedside lamps, small living areas, or spots where you want softer, ambient light rather than bright task lighting. Before buying, check that your fitting takes an E27 screw base, since bayonet fittings will not work, and think about whether warm white matches the room. Compare with other 5W LEDs on brightness and shape.
