Satco 20 W 12 V MR11 halogen bulb

The Satco S3465 FTD is a 20-watt halogen MR11 lamp that runs on 12 volts and produces a warm 2900 K light. It uses a GZ4 miniature two-pin base and delivers a narrow flood beam suitable for accent and display lighting. The bulb is rated for 2000 hours of average life and offers a colour rendering index of 100.

Check voltage and base before ordering

Verify that your fixture supplies 12 volts and accepts a GZ4 two-pin base, as this lamp will not operate on mains voltage or fit other sockets. Confirm the physical dimensions match the MR11 form factor to ensure proper seating in the housing. Ensure the narrow flood beam angle meets the spread required for your application.

Steady output over the rated lifespan

The halogen capsule maintains consistent brightness and colour quality throughout its 2000-hour rating without the rapid lumen drop seen in some technologies. Operating at the specified 12 volts keeps filament temperature stable for reliable performance during extended use. The CRI of 100 remains constant, preserving accurate colour rendition under sustained load.

Questions about this item

Does the bulb come with the GZ4 2-pin base already fitted?

Yes, the MR11 halogen bulb has an integral GZ4 miniature 2-pin base so no separate base is needed.

Should I pick this 20W 12V MR11 or a higher-wattage version for a low-voltage landscape fixture?

Choose this 20W 12V MR11 when the transformer and fixture are rated for 20 watts maximum; a higher-wattage lamp would exceed that limit.

What does the 2900K colour temperature look like once the bulb is running in a real fitting?

The 2900K output produces a warm-white glow similar to traditional halogen, with a CRI of 100 for accurate colour rendering.
