My purely subjective experience with the KR4 with E21A 4500K is the tint is a nice all purpose tint. It’s great for indoor and outdoor use for close to medium distance lighting (due to the floody optic; I tried the throwy optic and it had artifacts). I can use it for all but work, as it’s too big to carry in scrubs and I prefer the smaller Reylight with the Nichia 219B for an even rosier tiny for skin examination.
In comparison with the XP-L-HI and SST20, they definitely are greener with poorer brown color rendering but still useable for daily non-clinical settings. The E21A has not generated excessive heat in my daily use; I set ramp max at 130/150 and rarely hit that max and rarely use turbo. In real life use, I haven’t found much difference in heat issues between the E21A and the other emitters.
TL;DR: You’ll likely be happy with the E21A, it’s a good with floody optics and great for all purpose use.
I have been comparing 5000 and 4500 . If you need real white and a little more vibrant color, you go to the 5000 . Otherwise the warmer tint of the 4500 helps to have a more relax sight, not being induce in focusing .
Hank said the ano wears like regular ano.
I’m not entirely convinced, ano is a surface coating that is harder than the aluminum substrate…
On Ti I think it’s an etching where the distance between ‘etches’ affects the color reflected that we see. I bet an ano Ti knife guy would know more definitively…
Titanium anodization wears off extremely fast compared to a properly anodized aluminum surface. Tiny, long scratches called snail trails will show up almost immediately after being handled. Maybe it will hold up a little bit better on the body where the surface isn’t 100% smooth.
The colors will also fade when in contact with skin oils, but will restore once cleaned.
I was surprised to see that 26350 tubes for Emisar D4S and D4SV2 were shown as available in all colors. I emailed Hank and he confirmed that green and cyan were really in stock.
I will finally have a 26350 tube for my green Emisar D4S that I purchased a year and a half ago, before 26350 tubes were available.
