Ventilated place

Incandescent lamps and halogen lamps consume energy 4.5-5 times more than energy-saving lamps. For glow in such lamps, the principle of heating is used. In the first case, this is a tungsten spiral, in the second — a special gas. Such light sources can only be stirred in a well -ventilated place. Therefore, their use is limited to external lighting or lighting of the open cupboards, and the installation requires additional electrical work.
