Osram Sylvania has released s new survey about Americans’ awareness on light bulb changeover.

According to Osram Sylvania’s new survey, Americans’ awareness about using LED light sources as replacements for regular bulbs is growing. Americans come to know that federal legislation will phase out “most traditional incandescent lighting by 2014.” And the poll found that 55 percent of respondents were aware of that fact, up from 36 percent in 2010 and 26 percent in 2009.

According to Stephanie Anderson, a spokeswoman for Osram Sylvania, “Americans are increasingly prepared for this lighting transition.” She said the survey also showed that 62 percent of those polled had swapped out a light bulb over the last year to increase energy efficiency.

However, people are less clear about what details is going to happen beginning in January.Only 29 percent know it is the 100-watt incandescent lamp that will no longer be manufactured starting in 2012. (While its manufacture will be forbidden, the sale of existing stock will be allowed.)

The new legislation has declared that lamps that produce the approximate brightness of a 100-watt bulb can only use 72 watts to do so. In 2013, 53 watts will replace traditional 75-watt lamps to produce the same amount of light. The same rules are being put into effect a year earlier in California.

The survey also shows that only 13 percent of respondents said they were using LED light sources as replacements for regular bulbs, and 80 percent had heard of them. Only 68 percent were aware that the existence of the compact fluorescent lamp, or C.F.L.

Many companies plan to sell LED lamps that produce as much light as a 100-watt bulb.And currently, LEDs that create the equivalent of a 40-, 60- or 75-watt standard bulb have put into practice, although they can cost as much as $40.

But it seems that incandescent bulbs will not disappear in homes right now. As in years past, the Osram Sylvania survey found that around 13 percent of those surveyed said they planned to hoard standard light bulbs.
