So how do LED bulbs compare to CFL bulbs?
25,000-hour LED bulbs will last the same time as 2.5 10,000-hour CFL bulbs. We expect LED bulbs to become even more energy efficient in the future. Taking a few other factors into consideration, like manufacturing processes, it's been determined that a 25,000-hour LED bulb is about as energy efficient as a 10,000-hour CFL bulb over its lifetime. That's the standard that you need to beat with LED lighting, tempered by a need to keep initial costs low as well.
If you really want to change to LED lighting, you should look for bulbs that have a lifetime of more than 35,000 hours. At 35,000 hours, you get an energy efficiency that is 40% more efficient than standard LEDs. This translates to a 25-40% savings when compared to CFLs. The 50,000-hour LED bulbs are now twice as efficient as standard LEDs. This can lead to significant savings is the initial start up cost isn't too steep.
There are quite a few LED bulbs that can now last 50,000 hours. We've seen bulbs from EcoSmart, GE, and other manufacturers that have made things a lot more interesting. Typically, these bulbs sell starting at $15. The EcoSmart A19 is definitely a good choice if you're planning on converting your lighting needs to LEDs. The low cost ($18) and long life (50,000 hours) definitely make it an energy efficient solution to your lighting needs.
