Beautiful and warm hotspot when driven at 5000 mA. No corona, no tint shift. At 6000 mA very white but not aggressive. Surprisingly, works at 5 ma (moon mode - lower threshold) and some green shifting. The spill is useable but this is a thrower. LED well centered but care when soldering as mounting holes quite close (screw heads may short). The picture on left is moon mode, on right is the low mode. Used with K0B 26650 flashlight host, check my comment on that listing.
