Tronic LED Filament Bulb 4W E27 Warm White

Our review

This is a 4-watt LED bulb from Tronic with an E27 base and a warm white output of roughly 2700K. Its filament design copies the look of old incandescent lamps, so the glow stays soft and amber rather than stark. It suits anyone lighting a living room, bedroom, cafe or small shop where atmosphere matters more than raw brightness. Before buying, confirm your fixture takes an E27 screw base and that 4 watts gives enough light for the space, since output depends on lumens, which are not stated here. Compare with other filament LEDs on colour temperature, dimming support and shape.
