Differences of Incandescent, Halogen Lamp, CFL and LED Light Bulbs

We will need more lights at long night during the winter, and there have been so many kinds of light bulbs in the lighting market. Want to know which one is the best? You will get the answer from the above comparison chart.

Well, let's set that we will need the same brightness, say, 1600 lm light output. then we can compare the energy cost, the life span and the price of these 4 kinds of light bulbs.

Energy Cost
To product 1600lm light output, you need to input approximate:

• 100 watts for Traditional incandescent
• 77 watts for Halogen incandescent
• 23 watts for Compact fluorescent lamp (CFL)
• 20 watts for Light-emitting diode (LED)

Life Span
How long will you change your light bulb? A long-last light will save your maintain cost:

• 750 hours for Traditional incandescent
• 1000 hours for Halogen incandescent
• 10000 hours for Compact fluorescent lamp (CFL)
• 20000 hours for Light-emitting diode (LED)

Price
As the development of the technology, light bulbs are going cheaper and cheaper. Some bulbs are banned for costing too much energy, and some new kinds of bulbs are brought to live:

• $0.37 per bulb for Traditional incandescent
• $1.59 per bulb for Halogen incandescent
• $2.23 per bulb for Compact fluorescent lamp (CFL)
• $45 per bulb for Light-emitting diode (LED) (the price ranges different from $5.99 per bulb to more than $100)

From these data, we are clear that LEDs could be the best lighting solution, because it is energy-saving, last long for years, a slight expensive than other bulbs, but it worth. Also, here're more features of wholesale LED light bulbs:
1. It's safer (low voltage, no toxic mercury).
2. It doesn't need time to get to full light.
3. It emits less carboon footprint (eco-friendly and green choice).

Beside these comparison, you could refer to the previous post about why LEDs a better choice of lighting.
