Lumi

Yes, the Lumi 4.5W LED filament bulb is fully dimmable. You'll need a dimmer switch specifically rated for LED bulbs, as older trailing-edge dimmers designed for incandescent bulbs may cause flickering or buzzing. Most modern LED-compatible dimmers will allow you to adjust the light output smoothly from full brightness down to a low glow.

This bulb emits light at 2700K, which produces a warm white glow identical to traditional incandescent bulbs. It's ideal for creating a cosy, inviting atmosphere in living rooms, bedrooms, and dining areas. The warm tone is softer and less clinical than daylight or cool white bulbs, making it perfect for relaxed evening lighting.

E27 ES (Edison Screw) is the standard large screw fitting commonly used in the UK for pendant lights, table lamps, and floor lamps. The base measures 27mm in diameter with a threaded screw fitting. If your existing bulb has a large screw base rather than a bayonet (push-and-twist) fitting, this bulb will fit.

No, the Lumi has an IP20 rating, which means it's only suitable for dry indoor locations. It is not protected against moisture and should not be used in bathrooms, especially near showers or baths where water splashes may occur. For bathrooms, you'll need a bulb with at least an IP44 rating or higher.

This LED bulb consumes just 4.5 watts whilst producing light output comparable to a traditional 40-50W incandescent bulb. Over its lifetime, it will use approximately 90% less electricity than an equivalent incandescent, significantly reducing your energy bills. The low wattage also means it generates very little heat compared to older bulb technologies.

LED filament bulbs like the Lumi typically last between 15,000 and 25,000 hours depending on usage patterns. At an average of 3 hours per day, you can expect this bulb to last approximately 15-20 years before needing replacement. This is significantly longer than traditional incandescent bulbs, which usually last only 1,000-2,000 hours.
