This device is not very reliable, except for this, when listening to an annoying buzz; - Secondly, at low ambient temperatures, they ignite with difficulty and burn dimmer than at room temperature. - Thirdly, their high enough cost. Most often, daylight lamps are used in non-residential premises: offices, production halls, trading halls, pavilions. Since these lamps have a more rigid light, they are used in everyday life with plafonds mounted on lamps (sconces, floor lamps, table lamps). The plafonds scatter light and, thus, protect the eyes.

The name of the company and the country of manufacture must be indicated on them, and on the package - the manufacturer's address translated into Russian. The seller must have a certificate of quality. Remember that fluorescent tubes are filled with mercury vapor (2-5 mg), so do not allow damage to the bulb in the room.
