The new incandescent lamp of the Massachusetts Institute of Technology is three times more efficient than the LED
When the lighting industry engineers started producing more energy-efficient light bulbs, like Moscow's wholesale LED lights, many thought that the existence of incandescent bulbs was coming to an end.
However, a team of researchers at the Massachusetts Institute of Technology decided not to leave them just to collect dust. Instead, they changed the design and developed such an incandescent lamp, which in terms of energy efficiency is several times higher than LED and fluorescent lamps. The new lamp also imitates natural daylight much better than modern energy-efficient light bulbs, this circumstance may also sharpen the competition for the buyer.
The efficiency of traditional light bulbs (that is, cheap varieties of incandescent bulbs) is usually only five percent: 95 percent of the energy “warms” the atmosphere. The MIT team found that the filament inside the glass of a light bulb can be wrapped with a special crystal structure and “reworked” the energy that is usually lost. The result obtained during the testing of the design concept is an incandescent lamp that emits a familiar warm light, but its efficiency reaches 40 percent. In addition to this huge improvement over traditional lamps, the new MIT lamp also takes precedence over LED and luminescent lighting, since for such lamps the efficiency usually reaches about 14 percent.

Another significant advantage of the new lamp is the quality of the emitted light. Instead of the clinical white light of LEDs, the advanced incandescent lamp emits more natural light, which most closely simulates natural daylight.This achievement is associated with the “color rendering index”, which in traditional incandescent bulbs is equal to 100 (exact correspondence to daylight). The nearest LED or fluorescent lamp can only dial 80, but with most modern energy-saving lamps that are on the market today, this figure is much lower.
“It is also important to note that our lamp has demonstrated almost perfect color reproduction,” said the main researcher Ivan Celanovic. “That is why incandescent bulbs retain their dominant position for so long: their warm light for decades has remained preferable to fluorescent lighting.”
