Parts Desk Insights

Best Use Case: Use this MR-16 reflector bulb when your existing 12.8V DC, 10W MR-16 bi-pin halogen lamp has burned out and you want the reflector-equipped halogen output for the same light fixture housing.

Common Issues: The most common replacement mistakes are selecting the wrong base type (MR-16 bi-pin vs. other reflector or cap styles) and installing an incorrect voltage/wattage in the same fixture. If the fixture has a specific bulb code on the housing, match it before replacing.
