About EyourLife
EyourLife is an English-language website about LED lighting, light fittings and car lighting.
What you will find here
Free lighting calculators for room lighting (lux), watts and lumens, LED strip power supplies, beam angle and spot size, and battery runtime, and the articles section.
How the calculators work
Each calculator runs in your browser and only uses the numbers you enter plus the reference values shown on its page. Every tool page states the formula, the units, where the reference values come from and the limits of the result. The calculators cannot measure real lamps, batteries or rooms.
How articles are made
Articles are drafted with the help of AI writing tools and go through automated quality and policy checks before publication. Read the editorial policy for the rules they follow.
