Description
12V MR8 LED Bulb – 6 LED Low Voltage Replacement for 10W Halogen (25mm, 10–30V DC)
Upgrade your low voltage lighting with this 12V MR8 LED bulb, designed as a direct replacement for traditional 10W MR8 halogen lamps. With a compact 25mm diameter, low 1W power consumption and wide 10–30V DC input range, this MR8 LED is ideal for caravans, motorhomes, boats, campervans, off-grid systems, display lighting and low voltage fittings. It provides bright, efficient illumination while dramatically reducing power usage — perfect for leisure battery systems and mobile applications.
Designed as a Direct MR8 Halogen Replacement
This 6-LED MR8 uses the same cap and physical format as standard MR8 halogen lamps, making replacement quick and straightforward — simply remove the old halogen and fit the LED.
⚠ Important:
MR8 lamps are less common than MR11.
- MR8 diameter: 25mm
- MR11 diameter: 35mm
Please measure your existing lamp before ordering to ensure compatibility.
Why Upgrade to LED?
Massive Power Saving
Replaces a 10W halogen while using just 1W — ideal for reducing drain on 12V leisure batteries.
Stable 10–30V Operation
Fully regulated for use on 12V or 24V DC systems. Perfect for:
- Campervans & motorhomes
- Boats & yachts
- Caravans
- Off-grid cabins
- Low voltage display lighting
Reduced Heat Output
Runs far cooler than halogen — safer for enclosed fittings and delicate installations.
Long Life & Reliability
No fragile filament and backed by a 2-year guarantee for peace of mind.
Light Output Options
- Cool White: approx. 139 lumens – crisp, bright light ideal for task areas
- Warm White: approx. 122 lumens – softer tone similar to traditional halogen
Both options provide similar usable brightness to a 10W halogen, but with dramatically lower power consumption.
Important – Transformer Compatibility (Household Installations)
If replacing halogen MR8 lamps in a household fitting, please check your existing transformer. Many older halogen transformers require a minimum load (for example 10W–20W) to operate correctly. As this LED lamp uses only 1W, the transformer may not function properly and could cause flickering or failure to start.
For best performance, we recommend using a low voltage constant voltage LED driver or an LED-compatible transformer designed to operate at low loads.
