Light is very difficult to compare. As said, beam focus and penetration is more important than 'brightness' or light output.

I'm not sure if LED technology has improved, I'm sure it has, but an M6 F13 that I had with LED lights were not good. High beam was good in that it lit up the near world like a Castle Bravo, but didn't have good penetration at distance, which is what you want from a good headlight. Probably why they feel the need to supplement LED with Laser for long distance?

Regarding Lumens and the chart posted earlier, you need to take one thing into consideration, and that is that LED's flash, whereas Xenon pulse. So LED's go from full light output to zero light output repeatedly. Whereas Xenon produce waves of continuous light. That has an effect on measuring equipment, as it usually measures average light output. The human eye sees the light at it's peak value apparently and doesn't detect the flashing on off situation.
