To date, fluorescent lamps remain the most common lighting devices used to illuminate rooms. Most often they can be seen in corridors, various halls, office rooms, public rooms and residential buildings. These lighting devices are especially in demand at industrial enterprises, where there is no need to create an increased level of protection against exposure to a humid environment or dust.
Appearance
The appearance of fluorescent luminaires and general-purpose lamps is as wide and varied as the scope of their application. Lighting equipment of various types is displayed on shelves in many stores and is available in catalogs on the corresponding sites on the Internet. When choosing lighting fixtures, it is important to pay attention to the marking. On the marking, the buyer, firstly, will see the power indicator of fluorescent lamps. For example, LPO 1×18 or 2×36 – the number of lamps and their power. Secondly, you can pay attention to the base used (the most common marking is G13). In addition, such lighting devices can be equipped with electromagnetic ballasts. Are designated as «EMPRA» – in cases where a starter is present or «Electronic ballast» – with electronic system.
Other features
Also, when buying general-purpose fluorescent lamps, you can pay attention to the body of the lighting device. Some of them are made of polyester. Marking «SMC». In this case, the polyester is reinforced with fiberglass. This sheet material may contain resin, various fillers and reinforcing elements (fiberglass).

Another important point is the diffused light emitted. For these purposes, either the aforementioned polyester or a material made of polycarbonate can be used. It is indicated by marking. «PC». Polycarbonate is characterized by a certain increased stiffness and a fairly high impact resistance. It is also worth noting that this material does not lose such useful properties when the temperature changes (either a decrease or an increase). It is noted: that if the diffuser made of polycarbonate is bent in half and then released, then the material will bend and take its original position. Polycarbonate diffusers remain quite popular in industrial use today..
Styrene acrylonitrile diffusers are also used. «San» or polystyrene «PS». The latter retain their advantages and features over very long operational periods.
