LED light bulb, 13W (1400lm) E27, from Umage

If you're struggling with light bulbs and technical data, here's a brief explanation of the most important things you need to be aware of.
Today, brightness is measured in lumens instead of watts. You can roughly assume the following

15W = 140 lumens
25W = 250 lumens
40W = 470 lumens
60W = 800 lumens
75W = 1050 lumens
100W = 1520 lumens

In addition, you can also see that a light bulb has an RA or CRI value. This is the light's ability to reproduce colours and is rated on a scale from 0-100 RA.
100 RA gives the best colour rendering, which is what you get from daylight.
For an average home, you should choose light bulbs with an RA value of more than 80.

A chromaticity level will also be indicated. This is the colour of the light. A light bulb with a chromaticity of 2,700 - 3,000 has a warm light colour.
4.000-4,5000 gives a neutral to cool light and is the most optimal light colour to work in
If you need extra energy during the dark months, go for a kelvin rating of 6,000 or higher
