Those 3 lights on the left are all Crelant lights. The 2 smaller ones are from left to right the Crelant V21-A, Crelant V9U2, and Crelant 7G5CS. The one on the far right is a FandyFire STL-V6. All those Crelant lights are pretty bright especially the big one.
Here's a beamshot from the Crelant 7G5CS collimator head at 110yds.
Here's one zoomed in some at about 360yds.
