Satco S1956 20W MR16 Halogen Bulb 2900K

Dimmable 12V MR16 Halogen Spot Bulb by Satco

The S1956 from Satco is a 20-watt, 12V MR16 halogen bulb designed for low-voltage fixtures that use a GU5.3 base. It is suitable for damp locations. Key features include a 36-degree beam, 2900K warm white light, and a CRI (Color Rendering Index) of 100.

Key Features and Benefits of This MR16 Bulb

The 36-degree beam concentrates light for accent and focused lighting rather than broad coverage. A CRI of 100 shows colors accurately, and the 2900K warm white tone suits many interiors. The bulb is dimmable, and Satco lists a 2,000-hour rated life.

Where to Use the S1956 MR16 Bulb

This bulb is well suited for low-voltage fixtures that need a focused beam, where a clear halogen spot highlights displays or work surfaces. Its damp location rating covers protected humid areas, but it is not listed for wet locations or direct outdoor exposure.

Installation and Compatibility Checks

This is a 12V lamp, so it needs a low-voltage fixture or transformer and will not run directly on 120V. Confirm that your fixture accepts a GU5.3 (GX5.3) base, and that the transformer and dimmer support halogen loads. The bulb is 1.88 inches long and 2 inches in diameter.

Additional Buying Context

Halogen MR16 lamps use more energy than LED alternatives, so consider an LED version for lower operating costs. The bulb is RoHS compliant. Satco's manufacturer warranty is linked on the product page, though its terms are not stated there.
