So I have two lights, a 600 lumen that has a nice, wide beam and a 200 lumen that has a focused spotlight beam. The 200 lumen light is noticeably brighter. You can see its spot well defined within the light that comes from the 600. Also, if you stand in front of the bicycle and look back, the 200 lumen looks brighter. However, it's obvious that the 600 is putting out much more light, it's just spread around nicely. Therefore, from what I'm reading here, the 600 has more lumens and the 200 is greater in lux. Am I in the ballpark?
