LED Options: The most energy-efficient versions are available for all three bases and are LED-based. Compared to incandescent and CFL bulbs, they have longer lifespans and use less ene

How to Choose the Right Bulb

Consider Your Fixture

Ensure that you are aware of the fixture’s socket size. To find out if your light fixture demands E26, E27, or E12, check the label or manual. An inadequate fit or electrical problems may arise from using the incorrect base size.

Assess Your Lighting Needs
