Product Description
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
