Swap to LEDs and Smarter Bulbs
Replace high-use bulbs first—kitchen, living room, bathroom vanity—so savings appear immediately. Choose warm-white 2700–3000K for cozy rooms and 4000–5000K for task zones, then match lumens instead of watts. Many utility programs discount multipacks, shrinking payback to just a few weeks. Readers report first-month reductions when replacing twelve incandescents with nine-watt LEDs, while enjoying steadier light and cooler rooms during summer heatwaves.
