Energy-saving lamps, which managed to gain popularity among consumers moderately , have a serious drawback - they usually reach their maximum heating shortly after inclusion. In addition, in production are mercury compounds.
LED lamps often have lower power consumption - at least when it comes to the claimed characteristics. The disadvantages of these light sources include the difficulty of creating a cheap lamp with a wide angle of coverage, poor performance ratio of power consumption and light output and limited reserve to improve this ratio. In addition, LED lamps are significantly more expensive.
In the next year on the market may appear LED lamps warm range with an efficiency of about 150 lumens per watt.
Epistar development will bring to market LED lamps warm spectrum, which by their light output can replace the traditional lamp 60, 75 and even 100 watts. When the efficiency of 150 lm / W LED equivalent incandescent lamp will consume 75 watts only 5 watts. Now the cost of LED equivalent 40-watt incandescent in different countries ranges from $ 11.4 to $ 22.6. The cost of LED equivalent 60-watt incandescent lamp could fall to $ 10. The use of LEDs in the light source is an important trend, which allows the semiconductor industry to receive an additional incentive for development.
