Different light bulb suitable for different lighting area, some suitable for reading lighting, some suitable for cabinet lighting. But the traditional incandescent light bulb waste 90% energy in heat. Mr Ron Clearly a Electric expert from American Home Dept company said incandescent bulb is too low energy efficiency, it is the time say good bye to them.

Halogen lamp

Halogen lamp energy efficiency 28% higher than incandescent light bulb, illuminance is strong with clean light, and the life span is longer than traditional incandesent bulb, about 2-3 times of incandesent bulb.

CFL(energy-saving bulb)

People first time see CFL, the spiral energy-saving bulb in the end of last century. in namal the power consuption is 75% to traditional incandesent bulb, the life span is about 10000 hrs. In the old time, CFL start slowly, can not light dimmable all been solved by the technology increase. Now CFL get a big improvement both on the style and color and some type can do light dimmable. But a problem there include some mercury(Hg), so it is not good to the environment when waste recycle.

LED BULB

High price and small LED bulb use for Christmas light in the old time, now popular in lighting area. Mr Ron Clearly said LED bulb in lighting just like Cadillac in automobile. Compare to the traditional bulb, 85%-90% higher on light efficiency. life span can be 25000 hrs, it means if lighting 3 hrs per day, it can work for 20 years with our replacement, now the price is too high, but when mass producing, the price will be more accetable by ordinary people.
