Comparing LEDs with CFLs is like comparing oranges and apples. For starters there is no relation between
the wattage and light emitted by a CFL and an LED. Moreover, LED’s produce unidirectional light – this
means that it is easier to control the light. You can choose to focus it for spot lighting or use a lens for
diffused lighting applications. On the other hand, light emitted by a CFL, like that from incandescent bulbs,
is multidirectional and difficult to control. A lens can easily collect all the light emitted by an LED and
disperse it. A CFL on the other hand relies on a reflector to spread the light and a portion of the
light is always wasted. An LED lamp can thus be used to replace a CFL or incandescent lamp with a higher
light output.
