Check out the beauty of the beam Clemence created by frosting the lens on the Utorch S1 Mini.
sw45 w frosted lens (edges of beam are a smoothly diffused gradient, more like a McGizmo Mule):
contrast the beam from the stock aspheric, here with the 2000k E21A (edge of the beam is a sharp cutoff, more like a McGizmo Sundrop)
I like choices, both lens styles are good for different things. I prefer the sharp cutoff when the light is stationary, because I use it to illuminate things on a table in front of me at arms reach. otoh, the diffused beam is better when moving, creates less tunnel vision effect because the increase of brighness is gradual from edge to center.
Aspherics are a very unique type of beam, the outer perimeter is stronger than the middle, but the beam is very even accross the middle 90% of the beam. With the diffused beam, the edges are slightly less bright than the center. With a conventional reflector the edge is also less bright than the hotspot, but the differences are much less gradual…
Hotspots are good for situations where we want the beam to reach out for some distance, without spilling too much light into the foreground. An aspheric is exactly the opposite. It will light an object in my hands, in the center of my field of vision, better than it will light things further away, so an aspheric is basically useless for walking the dog, but fantastic imho, for a worklight.
Notice:
I caution people to be aware that Utorch S1 Mini have a reliability issue regarding the white wire. I cannot unconditionally recommend the light itself. otoh, I would buy Clemences LEDs again, and again, they are just awesome!
clear lens so I can see the gorgeous E21a, frosted lenses on a pair of SW45 9080
look closely at the two sw45, there is tint variation, the one on the right is more pink (relatively speaking)
left beam clear lens, middle beam frosted sw45 that is the middle light in the pic above (iow, the middle light looks less pink in the shot above, but still looks plenty pink in the shot below… tint looks different depending on the tint of other lights in the photo. Imo the tint of the middle light above, is more realistic. While I like the pink in Nichias, the SW45 on the right above is a bit excessive… really splitting snob hairs here… ignore if you dont understand
