  • Best for: Bathrooms, balconies and ceilings with limited height clearance

Low-power 5W LED runs from AC 220-240V without a transformer. Rated lifespan up to 30,000 hours signals fewer replacements over time.


Bright, eye-friendly illumination - thanks to cool white 6000K LEDs

5W LED chips deliver about 450 lumens with a 120° wide beam and a Ra 83 colour rendering index. The array and optic design focus light broadly for even coverage.

Strong cool-white output suits task areas and mirrors in bathrooms, reducing the need for extra fittings. Neutral rendering helps colours appear more natural under the light.

Slim-fit installation for tight voids - with 24 mm ultra-thin profile and 75-90 mm cut-out

Ultra-thin 24 mm construction and a mounting hole range of 75-90 mm allow fitting into shallow ceiling voids. Direct connection to AC 220-240V removes the need for an external transformer.

Fits where deeper downlights would not, making it ideal for renovations and flats with limited ceiling space. Direct mains connection speeds up installation for electricians and DIY-savvy installers.

Safer operation and heat control - with flame-retardant terminals and aluminium housing

Aluminium and PC housing combine with flame-retardant terminals to improve heat dissipation and impact resistance. Design reduces light loss while managing thermal stress during continuous operation.

Lower risk of overheating or fire hazard compared with lower-grade fittings, offering greater peace of mind in domestic settings. Durable construction helps the fittings hold up under regular use.

❓ Frequently Asked Questions

Q: Are these downlights suitable for bathrooms?

A: Yes. IP44 rating prevents water vapour and splashes entering the lamp body, allowing use in bathrooms, balconies and ceilings under eaves, but not for direct rain or immersion.

Q: Can the downlights be dimmed?

A: No. Non-dimmable specification means they must be used with non-dimming circuits or switches.

Q: Do the downlights require a transformer or driver?

A: No. Direct connection to AC 220-240V is supported, so no external transformer or driver is required.
