We get this question all the time and we’ve never published any official numbers.
It’s a pity that ‘lumens’ is such a popular measurement for comparing lights. Lumens gives you a number for the total amount of light energy but it tells you nothing about chromaticity, smoothness, angle, and intensity. It is especially painful that most manufacturers don’t give honest numbers anyway.
So before we tell you how many lumens you’ll get out of a Spikelight, we’ll look at some pictures and have a short lesson in light beams.
