LED, CFL and Incandescent Compared

  • LED – Light Emitting Diode
  • CFL – Compact Fluorescent Lamp
  • Incandescent – Traditional Filament Bulb

Often, Cade Electric’s customers ask for electricity usage and cost differences between LED, CFL or Incandescent Lighting.

The data in the table below is based on a lower quality LED bulb, a medium quality standard CFL (non-dimming) and a good quality incandescent bulb. (all are 60 Watt or Equivalent Light Output)

60 Watt Equivalent Bulb Comparison
  LED CFL Incandescent
Bulb Cost $12.99 $5.25 $2.00
Bulb Life (hours) 25000 10000 1000
Watt Usage 10 13 60

 

The incandescent bulb price is only 15% of the LED bulb price and 38% of the CFL bulb price. At first glance it may be difficult to justify the cost of the more expensive LED and CFL bulbs.

Giving a second look, the bulb life of the incandescent bulb is drastically disproportionate in relation to the price of the bulbs. The life of the incandescent is 10% of the life the CFL bulb and only 4% of the life of the LED bulb.

Since the LED bulb life is 25000 hours, it would take roughly 25 incandescent bulbs to match the life of the LED bulb. At today’s price, this means $12.99 for the 1 LED bulb and $50.00 for the 25 incandescent bulbs. There is potential for savings based on this comparison.

The next major consideration is the watt usage. The LED bulb consumes only 17% of what the incandescent bulb consumes and the CFL bulb consumes only 22% of what the incandescent bulb consumes. In either case, the familiar light from the incandescent bulb that so many are accustomed to is being pushed to the back shelves. The efficiency of CFL and LED lighting is too obvious to discard.

Below are comparison charts of the LED, CFL and incandescent bulbs.
