타깃 오디언스: Consumers Comparing Products

1. Don't Just Look at Lumens, Look at Lumen Maintenance

Check for "overrated" specs and brightness decay over time. Reputable products usually specify the lumen maintenance rate at the end of life.

2. Don't Just Look at Color Temperature Range, Look at CRI/Ra

For living rooms and bedrooms, 선택 전구 with a CRI of 80 or above to keep colors looking natural.

3. Don't Ignore Strobe

Use your phone camera. If you see distinct rolling dark stripes, the flicker is severe and the bulb is not recommended.

4. Don't Overlook Ecosystem Compatibility

If you already have Alexa or Google Home devices, confirm the bulb explicitly states support for that voice assistant.

5. Don't Just Look at the Appearance

Check the warranty, 애프터 서비스, and firmware update history. Only brands that continue to update will last longer.
