Osram 5w E27 ES 4000k LED Filament A-Rated GLS Light Bulb - Cool White

Q: What Are the Benefits of Switching to LED Light Bulbs?

LED bulbs use up to 90% less energy, last significantly longer, and offer flicker-free, instant lighting, making them a cost-effective and energy-efficient lighting solution.

Q: Can I Replace Any Bulb With an LED Equivalent?

In most cases, yes. Ensure the base type matches and check that the LED bulb offers a suitable wattage equivalent and voltage compatibility.

Q: How Do I Choose the Right LED Brightness and Colour Temperature?

Use lumens to measure brightness and kelvins (K) to choose colour temperature. Warm white is ideal for relaxing spaces, cool white suits task-focused areas, and daylight is best for detailed tasks or spaces needing natural-style lighting.

Q: Are LED Bulbs Compatible With Dimmer Switches?

Only dimmable LED bulbs work with dimmers, and the dimmer switch must be compatible with LED technology to prevent flickering or noise.

Q: How Long Do LED Light Bulbs Last?

Most LED bulbs last 15,000 to 50,000 hours, offering a significantly longer service life than traditional lighting options.
