I loaded up my new TK75 with fresh batteries today, had freshly charged batteries in my ElectroLumens Jumbo and went outside to make a comparison.
I was shocked to see the “smaller” TK75 produce a beam that was virtually identical in throw, intensity, spread and color as the big boy ElectroLumens SR90. Maybe instruments could detect a difference but to the eye, they were like identical twins.
I repeated my comparison five times and there was no real visual difference. Amazing performance of both.
The target I use is a house that is line of sight over totally flat surface (according to Google) 347 yards away. Both flashlights really lit that house up. Not as a ghost mind you, but really threw some serious shine on the building.
I am almost 100% satisfied with the new TK75 but not quite. I am disappointed there is no holster or belt carrier. But I should be able to find something to hang it on since it is not too large to carry around on a walk.
