Tronic Square E27 Warm White LED Bulb, 10W

Our review

This is a 10-watt LED bulb from Tronic with a standard E27 screw base and a warm white light output, sold in a square-shaped body. It suits anyone replacing an old incandescent or fluorescent bulb in a normal household socket, especially in rooms where the light stays on for long stretches and running costs add up. Before buying, check that your fixture takes an E27 screw fitting rather than a bayonet cap, and think about whether 10 watts gives enough brightness for the space. Compare it with other LED bulbs on lifespan, base type and colour temperature, since those matter more than the wattage alone. The main draw is efficiency: LEDs draw at least 75% less power than incandescent equivalents, and this one is rated to last 35 to 50 times longer than incandescent bulbs and roughly 2 to 5 times longer than fluorescent ones, which cuts both electricity and replacement costs over time. It is available on Sokonia.
