A few weak light bulbs or one strong one - luminous flux dependencies.

Hello.

I have the following dilemma. How many 35 W bulbs do I need to install to get a luminous flux of a 50 W light bulb. How to convert it? Are there any tables where such a relationship can be read? If so, I would like to ask for appropriate links or patterns.
For example, in the kitchen of a summer house, I want to install 3 LED bulbs, each giving 370 lumens (this corresponds to about 35 W of a traditional light bulb). After pointing them at one point, the light intensity or luminous flux will correspond to what traditional bulb?

Regards

To simplify it, please multiply the power of LED bulbs by 6 for cold ones or by 5 for warm ones and in this way we will get the corresponding power of traditional bulbs. On the other hand, you need to divide the power of LED bulbs should correspond to 20% of the traditional one. A 35W LED light bulb is the equivalent of a traditional 200W bulb. It's probably a bit too much if it is to shine directly in a bright room.
When it comes to the number of light sources, a few (2-4 for small rooms) give a better effect than one. There is less shade in the room, the atmosphere is more pleasant, warmer, the lighting is more even.

LED converter, and I know and use a traditional light bulb. Anyway, nowadays, with information about the luminous flux on LED bulbs, the matter is simple, it is enough to compare the lumens for the LED bulb and the traditional one (taking data from the Wikipedia table, for example). This does not answer my question.

As you certainly know, there are no LED bulbs in the store that would consume 35 W of power. In my speech, I only mentioned that a traditional 35 W incandescent bulb (not LED) gives a luminous flux of about 370 lumens. According to the manufacturer, this is how many lumens 4.5 W LED bulbs are equipped with 27 SMD 5050 LEDs, which I want to buy.
Returning to my question, I will try to present it more simply.
Suppose I have 3 light sources mounted in the ceiling. Each of them gives a luminous flux of 370 lumens. If I direct all of them at one point, what will I get the value of the luminous flux at that point? 400 lumens? 500?
Please let me know how to calculate it or provide a link to the table with this type of calculation.

If they shine at the same point it is easy because it is enough to add up.
Here you are, a 36W LED bulb

In my city, the market square is illuminated by stylish lamps with 70W COB LED modules.

You're spinning a bit. Luminous flux (what is measured in lumens) is something like power - the total amount of light produced by a source. Sure it does add up, but whether these sources will be single-point or not, it doesn't matter. The unit for the 'illuminance' of a surface is lux. This determines whether, for example, you can read without harming your eyesight.

In fact, I did not even know that LED bulbs with such high power are already on sale. However, their price is prohibitive for me, and I also need reflectors, not bulbs for circular.

That's why in the first post I wrote about the light beam or the light intensity, because I wasn't sure what to compare. Lux is from what I know about lumens per square meter. In that case, I am asking for information regarding the light intensity in lux as much as it increases when installing the next LED bulbs about which I wrote earlier.
Will it be as bright (colloquially speaking) as with one 105 W light bulb if, for example, it will be installed in a room with three 35W bulbs? Or darker, if darker, how much? Of course, the example values may be in lux. I will convert them into lumens and refer them to the light bulbs.

As far as I know, computer programs are used for conversion, e.g.
http://www.dial.de/DIAL/en/dialux-international-download/polski.html
illumination intensity will depend on the arrangement of lamps, the color and type of wall and ceiling surfaces, lighting directions and the height of the working surface

the direction of the lamps, not the walls and ceiling

Nobody really answered the author's question. I reheat the cutlet because I have the same "problem".
The question is not about any conversion of watts into old watts, into lumens, luxes, etc. but about this - will two 35W bulbs illuminate the room with the same power as one 70W ?? Otherwise, is it enough to have a chandelier with a few weaker ones instead of one very powerful light bulb and it will have the same effect? By peasant reason it seems so, but it may not be so.
Does anyone know about this?

I have the same question, will the two weaker bulbs shine with the same power as the one with the power being the sum of the two weaker ones?
Assuming that they will be mounted in one lamp next to each other.
