LED and CFL light bulbs are more energy efficient compared to Energy Saving Halogen, they also last a lot longer.
Based on a 60 watt equivalent, LED will run for up to 50,000 hours, CFL will last up to 10,000 hours but Energy Saving halogen is only expected to last up to 2,000 hours.
LED and CFL are the most efficient choices, LED bulbs will cost a bigger initial investment but will last a lot longer and eventually save you the most money. CFL bulbs are one of the cheapest ways to do an energy saving retrofit with the bulbs being a lot more affordable but they will need changing more often. Below you can find a table showing to the equvalent wattages between them all.
| **Type** | **Old Style Wattage** | **Energy saving Halogen** | **CFL** | **LED** |
