## Long description

Synergy 21 S21-LED-TOM00087 LED bulb provides neutral white lighting with a colour temperature of 4500 K and a luminous flux of approximately 420 lm in a compact GU10 form factor.

Its beam angle of up to 60° makes it suitable for directional lighting in residential and commercial settings where neutral white illumination is preferred.
Advantages
The LED bulb delivers efficient light output at low power consumption, offering steady neutral white illumination that approximates natural daylight without strong cool or warm bias. With an estimated lifetime of 35,000 hours and compatibility with a wide input voltage range, the lamp reduces maintenance and can operate reliably on standard mains supplies. The GU10 base enables quick installation into existing fixtures designed for this cap type.
Suitable for (tasks / use cases)
 Spot and accent lighting in kitchens, living rooms and retail displays
 Downlights and track lighting where neutral white colour rendering is required
 Task lighting over work surfaces, counters and reading areas

How to use
Ensure the power is switched off before installing the bulb. Insert the GU10 base into a compatible socket and rotate until it locks in place. After installation, switch the power back on and verify the lamp lights correctly. Use the bulb in fixtures that allow adequate heat dissipation and are designed for GU10 lamps. Do not use in enclosed luminaires unless the fixture specifications state compatibility with LED GU10 lamps.
Usage recommendations
For best performance, install the bulb in fixtures with some ventilation and avoid covering it with insulating material. If using with dimmers, confirm compatibility with LED dimming systems to prevent flicker. Replace bulbs in matched fixtures at the same time to maintain consistent light colour and output across a room.
