12V / 24V MR11 LED Bulb – 6 LED GU4 Low Voltage Halogen Replacement (35mm)
Upgrade your caravan, motorhome, boat or low-voltage lighting system with this MR11 (GU4) LED bulb, designed as a direct replacement for 10W MR11 halogen lamps. With standard 4mm pin spacing and a 35mm diameter, it fits straight into existing GU4 fittings while delivering bright, efficient illumination using just 1W of power. Ideal for campervans, marine cabins, display lighting, kitchen spotlights and off-grid installations where reduced power consumption and long life are essential.
This 6-LED MR11 has been specifically engineered to replace traditional 10W MR11 halogen lamps while dramatically reducing power consumption.
Using just 1.0W, it provides up to 132 lumens, offering excellent efficiency for 12V and 24V systems commonly found in leisure vehicles and marine installations.
It uses the same GU4 base with 4mm pin spacing, making installation quick and straightforward — simply remove the halogen and insert the LED. A protective glass cover over the front adds durability and a premium finish.

Important – Transformer Compatibility (Domestic Use)

As this LED uses only 1W, the transformer may not function properly. An LED-compatible transformer or constant voltage LED driver is recommended.
