4.5 Watt LED MR16 Bulb - 360 Lumens - GU5.3 Base - 12V

MR16 is a 50 mm reflector lamp typically at 12 V with GU5.3 pins. GU10 lamps are usually 120 V twist‑lock bases—different sockets and voltage.

MR16 LEDs commonly use GU5.3 at 12 V AC/DC; some specialized versions are GU10 at 120 V. Match base and voltage to your fixture.

Narrow 10–15° for tight accents, 25–40° for general spots, and 60°+ for floods. Lumens range ~300–800+ depending on application.

Many are dimmable with compatible low‑voltage dimmers and transformers. Use tested pairings to ensure smooth range and no shimmer.
