How to spend less running a LED light strip
- Cut the hours: A LED light strip at 4 h/day runs about $0.41/month — trimming one hour saves roughly $0.10/month.
- Lower the setting: running a LED light strip on a lower or eco setting drops the wattage directly.
- Upgrade efficiency: a newer LED light strip near 5 W uses far less than an old 100 W one.
- Kill standby: a smart plug or timer removes the ~1 W it draws even when off.
