![]() Conversely, the lower the number of lumens, the dimmer a light source will be. The higher the number of lumens, the brighter a light source will be. Watts, whereas, refers to the energy consumption of a luminaire. Therefore, the most accurate measure of brightness is lumens. For example, to produce 1600 lumens of light, you’d need a 100-watt incandescent bulb or an LED of approximately 15-watts. This is because LEDs can produce the same level of brightness as traditional bulbs using much less wattage. But the development of LEDs means that this yardstick is no longer accurate. With traditional light sources, if you wanted a brighter bulb, you bought one with a higher wattage. I’m sure many of you will be used to measuring the brightness of a bulb in watts. In simple terms, lumens are a measure of how much visible light a luminaire produces. Let’s start with lumens, which are often denoted as lm. More specifically, I’ll be talking about what they are, why they’re important, and whether they’re linked. In this post, I’m going to demystify the terms ‘Kelvin’ and ‘lumen’. Before you become overwhelmed and consider giving up, keep reading to the end of this article. When shopping for a new light bulb, there are lots of things to bear in mind. These two measures are completely independent and do not correlate. ![]() Lumens (lm), whereas, measure the total light output of a luminaire. Kelvins (K) are the units that measure the color temperature of a light source i.e., the color of white light it emits. Luckily, I’ve been in your position, and now I’m here to help! While terms such as ‘Kelvin’ and ‘lumen’ are intended to provide valuable information about a light source, in reality, they make matters much more confusing. Kelvins, lumens, watts, lux, CRI, beam angle, voltage, shape, base… Welcome to the world of LEDs! If you’re ready to upgrade your traditional light bulbs, prepare to be faced with a lot of specialist jargon. ![]()
