- Today’s incandescent light bulbs have a lifespan of around 1,000-2,000 hours.
- In 2007, incandescent light bulbs were banned in European Union countries and other countries due to their low energy efficiency.
- Compact fluorescent light bulbs (CFLs) were developed as an energy-efficient alternative to incandescent light bulbs.
- They use about 75% less energy and last up to 10 times longer.
- LED bulbs are the most energy-efficient option, using about 85% less energy than incandescent bulbs and lasting up to 25 times longer.
- The color temperature of light can affect our mood, behavior, and productivity, warm color temperatures (2700-3000k) are good for relaxation and comfortable feeling while cool color temperatures (5000-6500k) are better for concentration and productivity.
