Question

Which burns less energy - LED lighting or Compact Florescent?

Answer 1

Both, if you got them turned off.

Answer 2

LED

Answer 3

LED, they also last longer but currently they cost way to much  to compete with Compact Florescent bulbs.

Compact Florescent bulbs have an efficiency of around 15% while LEDs have an efishancy of around 50-60%

Answer 4

The technical answer to your question is a typical LED produces more lumens per watt than a typical compact fluorescent.  So, if you compare an LED to a compact fluorescent with the same lumen output, the LED will draw many fewer watts than the compact fluorescent, thus making LEDs much more efficient.

LED technology is rapidly improving with LEDs that can produce much higher lumen packages than in the past so that they don't have to be grouped together. I think LED's will find their place but may never equal the light output of HID's and T5 high output lamps.

Answer 5

LEDs use far less energy. As they become more mainstream, the cost will come down, much the same way the cost of the compact fluro came down.

Answer 6

When you compare light output apples to apples then the CFL has a big lead.

A CFL producing 60 watts of useable light takes 14 watts while to get an LED to do the same takes 11 watts.

The problem I have found using LED's is that the light is pure white, almost like moonlight where a CFL is a more yellow light that fills a space much better.

An LED works good for close work or background light but the CFL is better all around and the energy savings is negledgable.

Now the cost is where the two really part ways, my 60 watt LED was wholesale $69.00 while the CFL is a little over a buck.

Answer 7

it depends on the brand of light bulbs. Check the box to see how many watts it uses.

Answer 8

LED are more efficient.  Plus, they are safer for users and the environment than CFLs.  CFLs contain mercury, and although it's only 1/10 the amount found in a thermometer, it's still not exactly safe for you.
