There are three main types of eco-friendly light bulbs available on the market: halogen incandescent, LED and CFL.
Halogen incandescent lights consume less power, yet they are still not as energy efficient as LED and CFL. To put it into perspective, to produce the same amount of brightness as a 60W incandescent light bulb, you would need 42W for halogen incandescent light bulbs, 15W for CFL and 12W for LED.
When it comes to the lifespan, halogen incandescent lights have similar durability as the traditional incandescent lights. CFL can live up to 10 years while LED can go up to even 25 years of use.
