We realized that an energy efficient bulb:
- Uses about 70-90% less energy than traditional incandescent bulbs
- Lasts 10 to 25 times longer and saves $30 to $80 in electricity costs over its lifetime
- Produces about 70-90% less heat, so it’s safer to operate and can cut energy costs associated with home cooling
We proved the efficiency of the bulbs by placing heat sensitive sheets behind them. The bulb that uses more of its energy for light, didn’t release much heat onto the sheet. Look at all the colors that were displayed on the heat sensitive sheet from the less efficient bulb.
