Light Bulb Purchasing Checklist - How to Choose the right ENERGY STAR Qualified Bulbs

Oct 12, 2026

Bulb purchasing guide focused on selecting ENERGY STAR® qualified bulbs based on fixture compatibility, dimming and 3-way requirements, and color temperature preferences. It explains how “Dimmable” and “3-Way” labels relate to dimmers and three-way sockets, and recommends checking compatibility with photocells, motion sensors, or timers. The guide then helps match desired brightness by converting incandescent wattages to lumen ranges, and recommends common color options such as warm, soft, cool, neutral, and daylight.

FAQs

How do I know if a bulb is compatible with my fixture's dimmer or controls?

Choose an ENERGY STAR® qualified bulb marked “Dimmable” for dimmers, and check for “3-Way” when needed. For photocells, motion sensors, or timers, confirm compatibility with the manufacturer of your device.

What do the Kelvin (K) numbers mean for light color?

Lower Kelvin numbers look more yellowish, while higher numbers appear whiter or bluer. The guide lists options such as Warm White (around 2700K) and daylight (around 6500K).

How do I pick the right brightness compared with my old incandescent bulbs?

Use the chart but focus on lumens to get the same light output. Match your current incandescent wattage (e.g., 60W) to the listed minimum lumens range and ENERGY STAR qualified bulb wattage range.
