Energy-saving lamps: Pros and Cons
Fluorescent lamps have a different color temperature, which determines the color of her burning: 2700 K - a soft warm light 4200K - daylight (white), 6400 K - cool white. Color Temperature is measured by degrees - the lower it is, the closer to red light, the higher - the closer to blue. The packaging of such goods must be present, this marking. For home use more acceptable lamp warm or secondary (fluorescent) lamps produce less heat. Touching them by hand, you can not get burned.
Low heat makes them brittle in bras. By uniform distribution of light on the bulb they do not dazzle the eye, the glow from the lamps smooth, flicker-free. An important factor is the quality of the materials from which they are produced, also of the reliability and life of the - 3 to 12 thousand hours. This has a significant impact on the cost, but allows at least a year of relamping. Buying the cheapest product, there is a risk to face the fact that in 2-3 months the quality of lighting can dramatically decrease.
The main drawback of energy-saving lamps, the presence of mercury vapor in them. Therefore, in dealing with the problems of state energy conservation should be an integrated approach, before implementing the use of such fixtures, it is important to consider the question of their disposal. Otherwise, they can be a time bomb, cause irreparable damage to the environment, and thus the health of the people.
