Energy Consumption Comparison: Gas Fluorescent Lamps vs Incandescent Bulbs, Savings & Efficiency

Hello. I am wondering about the savings of gas fluorescent lamps compared to incandescent bulbs. I have no idea about the details, but since I was a child, I was taught that a light bulb is to be turned on and off, and a fluorescent lamp once lit - even if it is lit for many hours - comes out much more economical. How does it look in practice? In the company where I work, it is constantly repeated to turn off the lights when you are not in the room, and we have fluorescent lamps everywhere. Could any of you shed some light on this for me? ; ) I'm looking for some nice statement, maybe charts - which comparatively show which type of lighting is more economical, taking into account the on / off, or with how long the planned time of absence in the room, it pays to turn off the fluorescent lamp.

Constant switching on and off of fluorescent lamps shortens its life, but does not affect energy consumption to a significant extent.

For example, one fluorescent lamp has 22W (watt), which is the power consumed by the bulb.
You definitely have more than 20 fluorescent lamps in the company. Therefore, 20x22 = 440W and this is the power that all fluorescent lamps consume. 440W is not such a small power and that's why they tell you to turn off the lights.

What about the efficiency of the fluorescent lighting system? you didn't consider it...

440W isn't much at all. People often install hundreds of bulbs, five of them, and there are already more than 22 fluorescent lamps.

In the company, the costs of electricity and the costs of new light bulbs are calculated differently - it is often cheaper to extinguish.

If you meant linear fluorescent lamps under the slogan "fluorescent lamps", then in addition to the characteristics of the source itself, the type of equipment that works with them is also important. You will find a graph of durability vs. switching cycles for individual accessories Here

Fluorescent lamps have the disadvantage that it takes a while to reach the rated flux. Contrary to some myths, during start-up (it takes up to 5 minutes) they do not consume more energy than their rated values, but their efficiency is reduced during this time. If it is lighting in a company, you probably need to obtain a level of lighting close to the norm - eg 500lx for working with computers. If you want to do it with light bulbs, it will take up half the ceiling and make a nice heater for the winter. As a rich company, you can always get rid of fluorescent ailments and put on LED.
