Dimmable lights let you control brightness to suit your space or mood. Whether you need a soft glow or full illumination, this feature enhances comfort, ambiance, and energy savings in homes, offices, or hospitality spaces.

CCT lighting lets you select from warm, neutral, or cool white tones. In many products, the colour temperature is chosen before fitting, while in others like mirrors, it can be adjusted anytime to suit your needs.

This feature means the light comes with a built-in or external LED driver, saving time and cost on separate purchases. Drivers regulate power to ensure safe, efficient performance, especially important for LED lighting systems.

An IP44 rating protects lights against splashing water and solid objects over 1mm. These lights are ideal for use in bathrooms (Zone 2), utility rooms, or sheltered outdoor areas where occasional moisture is expected.
