The German company ledo LED technologie GmbH recently designed the “bulled†series of improved LED bulbs. The three bulbs are similar in size, shape and brightness to incandescent bulbs, but consume only 85% of the power. A single LED light bulb consisting of 11 dimmed LED light modules. This light bulb has 11 watts, but it can provide the equivalent of a 60-watt incandescent bulb. Fluorescent lamps are another kind of energy-saving light bulbs, which have a low color temperature and emit white light. By contrasting with fluorescent lamps, the designer set the "bulled" color temperature to 2800K so that it can emit warm and natural light. Because of the special shape of the bulb, it can scatter 330 degrees outward. Its service life is 80,000 hours and it can be used for 80 years within the scope of normal use.
