Notes:

– Cost of electricity will vary. The figures used above are for comparison only, and are not exact. Residential energy costs among the various states range from 28.53 cents (Hawaii) to 6.34 cents (Idaho) per KWH.

– The cost per bulb for LEDs may vary. We used the figure of $12.95 (for a 60 watt equivalent LED bulb) as an average among lighting retailers.

– Estimates of bulb lifespan are projected, since it would take about 6 years of continuous lighting to test. Some manufacturers claim the new LED bulbs will last up to 25 years under normal household use(Based on 3 hours use per day).

– Bulb breakage and bulb replacement costs have not been factored into this comparison chart. Incandescent bulbs and CFL bulbs are more easily broken than LEDs, which increases their cost of use.

– Most LEDs come with a minimum 2-year guarantee. Any defective LED bulb will usually fail within this time.

– Dimmable LEDs cost about 40% more than non-dimmable LEDs of similar wattage.
