Yes, it’s the bigger twisties for my own testing. They’re reflectored lights, still looking for TIR replacement for them.
You can order the lens separately, just PM me what you need.

It’s funny how the Optisolis appeals more than E21A, unlike anticipated from the poll result. As per yesterday’s orders, JetuE21A/E17A orders were much less than Jetusolis.
Enough for today, time for cells regeneration… I need to grow back fingerprints I lost from lapping 100pcs tiny copper MCPCBs. Good night everybody!
On your main page it doesn’t show the E21A under the new arrivals. I didnt even see how people were ordering it until I went fully into the shop another day.
The more I think about a relevant host for optisolis the more I am zeroing in to meteor m43. A good thing about this host is that you can remove some or all optics and get an optimal beam profile - from mule to spot with everything in between. And 12 leds @1amp each would provide enough light for almost anything
I havent tried that, but the mcpcb in an m43 is designed in a way that leds sit between long stretches of copper which allows for some flexibility in placement AND perhaps adding many more leds in addition to the 12
The cool Optisolis leds use a special 420nm led under the phosfor to prevent a dip in the cyan region of the spectrum, this gives them that extra bit of colour rendering. The warmer Optisolis use a conventional 450nm led because the blue/cyan part of the spectrum plays less of a role and going with the 420nm led does not help much. Therefore it does not stand out much compared to the very high CRI version of the E21A.
So, with anything lower than 3000K, E21A is a better option. Better invest in longer regulated runtime. To the naked eyes its extremely hard to see any difference between 3000K and 2700K Optisolis vs 3000K and 2700K (mixed) E21A. From Maukka’s test graphs there’s indeed a substantial higher CRI in color samples. They come from different phosphors mix I guess. As Djozz observed a year ago, Optisolis is the first Nichia with green phosphors, other than obviously, single color green E21A. This green phosphor can be excited by normal 450nm LED too.
