Frequently Asked Questions

How much do LEDs really save?
A single 10W LED replaces 60W incandescent, saving $8-10/year in electricity. Over 15 years, that's $120-150 savings minus $5-15 bulb cost = $100+ net savings per bulb.
Why do some LEDs look bad?
Low-quality LEDs have poor CRI (color rendering). Choose LEDs with CRI 90+ for natural light. Color temperature matters too: 2700K = warm, 5000K = cool/harsh.
Do LEDs work with dimmers?
Not all LEDs are dimmable. Look for "dimmable" on packaging. Some dimmer switches need upgrading for LED compatibility. Expect to spend $20-30 for LED-compatible dimmers.
Are incandescents being banned?
Yes, most incandescents are being phased out due to energy inefficiency. Some specialty bulbs remain available. LED technology now matches incandescent warmth and quality.
When should I use incandescents?
Only for rarely-used fixtures (closets used 5 min/day), vintage/decorative applications, or when heat is desired (heat lamps). Otherwise, LED is always better.
