LED bulb Synergy21 Retrofit 4W GX5.3, 400 lm, warm white 3000 K, 60° beam
Synergy21 Retrofit LED bulb with a GX5.3 base provides 400 lm of warm white light (3000 K) while consuming only 4 W. Intended as a direct replacement for low-voltage GX5.3 halogen spots, this lamp delivers focused illumination with a maximum 60° beam angle and an estimated lifetime of 35,000 hours. The compact retrofit design fits fixtures that accept GX5.3 caps and is suitable for accent, display and task lighting in residential and commercial environments.
The LED bulb reduces energy use compared with equivalent halogen lamps while maintaining warm-coloured light suitable for living spaces and display applications. With an estimated 35,000 h lifetime and a stable lumen output of 400 lm, the bulb lowers maintenance needs and replacement frequency. The 60° maximum beam angle provides controlled light distribution for task and accent lighting, and the GX5.3 base ensures compatibility with existing low-voltage fixtures designed for this cap.
Ensure the fixture is compatible with GX5.3 two-pin low-voltage lamps and switch off power before replacing an existing bulb. Press the bulb gently into the GX5.3 socket until it sits securely. After installation, restore power and check the beam direction and coverage; adjust the fixture orientation if required to achieve the intended accent or task illumination. For dimming use, verify compatibility with the fixture's dimmer and transformer if present.
Use this Synergy21 Retrofit 4W GX5.3 bulb in fixtures designed for low-voltage GX5.3 lamps and, when applicable, pair with compatible electronic transformers or dimmers. Avoid exposure to excessive moisture unless the fixture provides appropriate ingress protection. For display lighting, position the lamp to minimise glare and to highlight objects without overheating the illuminated surface.
