There from the end of the problem
More than a century, to buy light bulbs is a fairly straightforward and clear the transaction - people from the wattage indicated on the package to determine what kind of bulb to purchase.
But the government wants the next generation as a measure of the brightness of standard bulbs. That means that with the lumen (luminous flux unit) to distinguish between different light bulbs. Consumption in a light bulb to reach 4.4 billion the country, this is a rather difficult task.
Home Depot's purchase of light bulbs Jorge Fernandez said: "Customers have to spend some time to adapt to this change, over many years to get used to."
U.S. Federal Trade Commission proposed that all bulbs must be packaged to reflect the brightness of the lumen on the top, the wattage marked on the "energy" item below. Light bulb packaging must indicate the annual energy consumption of this lamp is about how much lamp life, and cold or warm light intensity and so on.
The idea is to help people choose the right light bulb, so that they no longer think of how many watts the bulb is, because in the future manufacturers will produce more and more energy-efficient low-wattage light bulbs.
New packaging launch scheduled for June this year, but the lighting industry's request may be delayed for six months. It would apply to traditional incandescent, fluorescent and energy-saving light-emitting diode (LED) bulbs.
The brightness of bulb wattage not so good measure, because even if the same wattage bulb will be different. A 60 watt bulb about 800 lumens, but different manufacturers lamp brightness will be different, the lowest is only 750 lumens, the maximum can reach 1049 lumens.
The future, wattage light bulbs will no longer be the measure of the intensity of the standard. From January 1, 2012, the United States will begin phasing out the 100 watt conventional incandescent lighting manufacturers will use 72-watt bulb instead of the traditional 100-watt incandescent. A year later, they will use energy-saving light bulbs to replace 28% of the traditional 75-watt incandescent. To January 1, 2014, 60-watt and 45 watt conventional incandescent light bulbs will be phased out.
