Bulb

The type of bulb that the light bulb is equipped with.

Transparent. Transparent flasks practically do not reduce the brightness of the light, but the light itself is sharper than from frosted lamps. They are considered optimal for lighting fixtures with transparent shades, as well as for crystal chandeliers and other similar fixtures, the design of which is designed for a beautiful play of light on corners and edges. In addition, in halogen lamps (see "Type"), other types of bulbs are practically not used — for a number of technical reasons.

Matte. Frosted flasks have a soft glow — due to a slight decrease in brightness compared to transparent ones. They are recommended for use in lamps with frosted shades, as well as for lighting children's rooms: the light attracts the attention of small children, and it is safer to look at a frosted light bulb. Also note that non-coloured fluorescent lamps (see "Type") are, by definition, made opaque.

Coloured. Flasks painted in a certain colour provide a glow of the corresponding shade. Usually, such lamps are used for decorative purposes, but other uses are possible — for example, for colour temperature correction in a photo studio. In addition, this category also includes the so-called. "black light lamps" — lamps that emit mainly ultraviolet light and very faintly glow in the visible range. Ult...raviolet from such lamps is relatively safe for humans, while it makes various substances and materials glow brightly. This effect is used both for entertainment and decorative purposes, and in quite practical areas of activity — chemistry, medicine, forensic science, etc.

Consumption

The power consumed by the light bulb during normal operation. The lower this indicator, the more economical the model and the cheaper it will cost to operate. In traditional incandescent lamps, the brightness of the glow also depended on the power, however, different types of lamps are presented on the modern market, with different efficiencies. Therefore, it is possible to uniquely link the power consumption and brightness only in lamps of the same type (see above), and to compare different types of models, you need to use the LON analogue (see below).

Luminous flux (brightness)

The conditional "amount of light" produced by a light bulb in normal mode. The higher the luminous flux, the brighter the light and the more clearly the illuminated scene will be visible. Note that lumen values are used primarily for special purposes; in everyday life, the estimation of brightness by the analogue of LON is more popular (see above), and here the ratio is as follows:

— 40 W analogue LON corresponds to a brightness of 370 lm;
— 60 W — 550 lm;
— 75 W — 800 lm;
— 100 W — 1200 lm;
— 150 W — 1900 lm;
— 200 W — 2700 lm.

Note that the principle "the more the better" in the case of the brightness of light bulbs is not always applicable. And the point here is not only energy consumption: too bright light is harmful to the eyes, leads to rapid fatigue and psychological discomfort.
