Buying Guide
What to consider when choosing outdoor flood bulbs

- Fixture compatibility: PAR38 bulbs fit many exterior cans; check base type (E26) and size to ensure a proper fit.
- Dimmer compatibility: If you want mood lighting, choose dimmable options and verify compatibility with your dimmer switch or fixture.
