Sounds like what you’re describing is the hotspot “washing out” the subject. You need a triple, quad, or multi-emitter in a TIR optic, (pure flood - no concentrated hotspot) Astrolux MF01 219C maybe?
I recently got one of these with Nichia 219C 5700K (tint is pure white) 720lm so no where near as bright as this TC20, but it’s no slouch either, and great for reading those paint cans JAXMAN-E2L-3LED-TIR-LENS-flashlight-18650
