Philips Ultra Glow 3-in-1 LED Downlight, Round

Philips Ultra Glow 3-in-1 LED Downlight is a recessed false ceiling fixture from the Philips Prime Plus series that combines three colour temperatures- Warm White, Natural White, and Cool White – in a single ultra-slim downlight. Switching between modes requires no apps, remotes, or rewiring: a simple 2-second ON/OFF toggle on any standard wall switch cycles through the colour sequence, with a memory function that recalls the last used mode after the light has been off for an extended period. Available in 10W and 15W, it is engineered specifically for POP, gypsum, and metal grid false ceilings with cutout requirements of 11cm and 14cm respectively.
The core value of the Ultra Glow 3-in-1 is flexibility without complexity. A single fixture installed at construction stage can serve as warm ambient lighting for evenings, neutral task lighting for daytime, and cool white for focused work – eliminating the common post-renovation regret of having chosen a fixed colour temperature that doesn’t suit every activity or time of day. With 100 lumens per watt efficiency, a 25,000-hour rated lifespan, and Philips EyeComfort certification covering flicker-free operation, anti-glare design, and CRI >80 colour rendering, it delivers professional-grade illumination quality that justifies its place in residential and commercial interiors alike.

Key Features

3-in-1 Scene Switch Technology: Toggle between Cool White, Natural White, and Warm White using any standard wall switch – no smart home system, app, or remote required.

EyeComfort Certification: Flicker-free LED driver eliminates 50Hz/100Hz strain frequencies; anti-glare recessed design reduces direct light exposure; IEC photobiological safety compliant.

100 Lumens/Watt Efficiency: High efficacy output delivers bright, even illumination at low power consumption – suitable for both 10W and 15W installations.

Ultra-Slim False Ceiling Design: Low-profile recessed form factor fits POP, gypsum board, and metal grid ceilings with a minimum 3-4 inch ceiling clearance requirement.

25,000-Hour Lifespan: Rated for over 22 years at 3 hours per day use- significantly reducing replacement frequency and lifetime cost versus conventional downlights.
