A lamp that sheds enough light to make it comfortable to read a book should offer 700 to 800 lumens of light. A well designed LED light bulb will need 10 to 12 watts of electricity to produce 700 to 800 lumens. But that’s all, just 10 watts. 300 to 400 lumens is plenty for hallway lighting or just to get around in a room, and that usually requires 6 to 8 watts. LED light bulbs can last up to 25,000 hours. Right now, you will pay from $5 to $10 for a bulb. If you use the light bulb for 2 hours per day, it would last at least 34 years. There is no mercury in an LED bulb and they are usually recyclable as metal and plastic.

For a solar powered house, LED lighting is indespensible. For a household using power from the local power company, LED lighting will bring your energy cost down substantially if you tend to keep a lot of lights on for long periods. If you start now, you start saving energy now. If you wait 5 years, the price of LED bulbs goes down, but the price of power goes up. Why wait?

LED lighting WILL dominate the market and become the standard. You may as well get to know them now. Makers are claiming that within 5 years, most of these prices will come down to $10 per bulb. The industry is aggressive and growing fast. According to Haitz’s Law, the LED equivalent of Moore’s Law, the cost per lumen falls by a factor of 10 every decade while the amount of light generated by an LED increases by a factor of 20. So expect very cheap bulbs that provide good lighting and need barely any electricity in the near future. Amazing! Yes?
