Common use is a clue, not proof. The fixture label and model documentation take priority over a visual match.

You may see these shapes with a GU10 base. The base code does not guarantee the bulb width, length, beam angle, or clearance.
Before you buy a replacement
- Do not confuse GU10 with straight-pin GU5.3 lamps.
- Check beam angle and bulb length before replacing a spotlight.
- Range-hood installations may have specific heat requirements.
