Luminescent lamps (ll)

Luminescent lamps have several advantages over ordinary incandescent lamps:

LL are energy -saving light sources. For example, an incandescent lamp with a power of 60 watts has a light output of 700 lumens. Luminescent lamp with a power of only 13 watts has a light output of the same 700 lumens.

Ll serve 5-10 times longer. For example, incandescent lamp when using 2-3 hours a day, you have to change an average of 1-2 times a year. When using fluorescent lamps, 2-3 hours a day, a lamp replacement will be required after 3-5 years.

LL, compared with a regular incandescent lamp, have more lighting options: warm (2,700 K), like incandescent lamps, as well as cold (4,200 k) and daytime (6,400 K).
