Read these five fields before ordering
Use the old bulb and fixture label together. A shared base or wattage figure answers only part of the fit question.
- 01
Socket and shape
Match GU5.3 exactly. The MR16 code describes the bulb envelope, not the socket. Open the GU5.3 base guide. Check the MR16 shape profile.
- 02
Electrical rating
The source lists 12 V. Confirm that against the fixture and local supply.
- 03
Brightness, not “watts”
Target about 360 lumens. The 4.5 W figure is input power, not brightness.
- 04
Physical clearance
The official maximum overall length is 1.85 inches. Check shade, cover, and neck clearance.
- 05
Heat, controls, and location
The source approves totally enclosed fixtures; it is marked dimmable; the location rating is Damp.

GU5.3 · Straight bi-pin reflector base
GU5.3 uses two straight pins spaced a nominal 5.3 mm apart. It is commonly paired with MR16 reflectors but does not itself define voltage or beam angle.
