Luminous Energy Converter FAQ
Are the conversions exact?
Yes. Lumen-second is defined as lumen times time; we use exact relationships like 1 lm·h = 3600 lm·s and apply SI prefixes precisely.
Can I convert between lumen-second and lumen-hour?
Yes. Enter your value in lm·s and select lm·h as the target (or vice versa); results update instantly as you type.
Does this handle very small or very large luminous energy?
Yes. You can convert down to mililumen-second or up to kilolumen-second with high precision using Decimal arithmetic.
