Doc and Ven, any artifacts from the shiny surface of the pill?
Good choice on the dark colored SS bezel ring.
Depends on the bezel ring really, i can get a slight gold bit in the outer spill edge with a gold bezel ring for an example. If a copper shell, depending on the set up, possible slight golden parts in outer spill(small and not in eye line). This is being real picky tbh and is no issue for use. You have to look unnaturally to see it if makes sense and is not part of the beam you would use. Under normal use it can not be seen(have to deliberately hold light and look to outer spill edge) which is kind of like using a thrower type light , looking through the crenelations on the outer spill..........we dont do it.
For the perfect beam, real close up use then a single LED would make more sense, however triples/quads have the output when needed. I tend to use the triple and quad at 20 or 30% as a low level and 100%(2 mode or sometimes set to 3 mode). Always starts in the low mode ................that is not really low(500+ lm at a guess).
IMO everyone should at least have a mule in their collection, simply because they are super useful. No hot spot to wash anything out, just a flood light for seeing everything around you. There are applications that are not suited obviously (hunting for one! ) But for general uses, from working on something, needing to light up the immediate area or even a walk and to flood the path ahead.
Another advantage of mules, when working on something or needing to illuminate a subject, you dont need to position the light. Trying to avoid being dazzled from intense hot spots or struggling in dim spill. You can lay it on a floor and it will illuminate a subject much higher up. Also you can use high outputs close up without it hurting your eyes.
