Tronic Filament LED 4W E27 Screw Bulb

Our review

This is a 4-watt Tronic filament LED lamp with a standard E27 screw base, the fitting used by most household pendant lights, table lamps and wall sconces. Filament LEDs are built differently from ordinary bulbs: many small LEDs sit in series on a clear substrate, often glass or sapphire, which is why the light spreads evenly instead of coming from one bright patch. That makes this type a sensible pick for visible fittings where you want the bulb itself to look good, and for small lamps where a gentle 4W output is enough. Before buying, check that your fixture takes an E27 screw cap rather than a bayonet or small Edison screw, and think about whether 4W gives the brightness you need for the room. If you want more light, compare higher-wattage filament lamps in the same fitting; if you want a warmer or cooler tone, check what colour temperature the seller lists, since that detail is not given here. Also compare dimming support if your switch is on a dimmer, as not every filament LED is dimmable. The bulb is available on Sokonia.
