This can be calculated if you happen to know your bulb's lumens per watt, using this equation: Lumens = Watts x lumens per watt.
LED lights can produce up to 1,000 lumens at approximately 75 lumens per watt.
A bulb will last about 10,000 hours and produce up to 125 lumens per watt compared to 39 lumens per watt for standard fluorescent lights and 18 lumens per watt for standard incandescent bulbs.
They produce up to 125 lumens per watt compared to 39 lumens per watt for standard fluorescent lights and 18 lumens per watt for standard incandescent bulbs.
However, it can be said of COB chips that the ratio of lumens per watt is very high, typically 80 lumens per watt minimum to well over 1oo lumen per watt.
For example, an LED panel with a 3600 lumen output and a power rating of 45 Watts would have an 80 lumens-per-watt rating (80 lm/W).
Efficacy is the rate at which a lamp is able to convert electrical power (Watts) into light (Lumens), expressed in terms of lumens per watt (LPW).
Three modes from 180 lumens, 20 lumens, and 1 lumen

A lumen-to-weight metric of the device is at least 4000 lumens per kilogram.
This is measured in ANSI lumens, generally referred to simply as lumens.
Varia UT800 features 5 light modes, including high (800 lumens), medium (400 lumens), low (200 lumens), night flash (100 to 300 lumens) and day flash (more than 700 lumens).
Some of the common wattages vs. lumens for incandescent bulbs are: 40W equals 450 lumens, 60W equals 800 lumens, 75W equals 1100 lumens and 100W equals 1600 lumens.
