[Optisolis/E17A/E21A] Jetbeam Jet-µ

I see a couple of heads from something larger in there. Is there a Jet-1 (AA) version being prototyped?

I’m interested in a couple different CCT’s each of the Optisolis and E21A mounted on MCPCB’s, plus optics to modify my E05’s. Are you prepared to offer those currently, and if so how do we order them?

If you’re not prepared to offer those parts separately yet, that’s perfectly fine, too. I can wait to place my order.

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.

Ordered a JetuE21A 5000K :slight_smile:

Now I´m quite excited
Thank you for the opportunity :+1:

I have a question, I’m trying to find if the Jetusolis ships with a 20 degree lens, or a 30 degree lens?

Only with 30°, will fix the description. 20° still cast ugly beam.

Ordered e21a version @3000k.

While I am a big fan of optisolis, I think that in this particular flashlight an e21a just provides for a more balanced set of features

Exactly!

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.

Ordered Jetusolis 4000K, curious to see it in real life.

Thanks, it’s fixed now.

If you go for Optisolis, better go with the 5000K one. The 4000K and below are quite similar to the E21A.

I was about to say the same thing too. But that really depends on his needs. For me, the warm Optisolis will be used for calibrated/comparator lights.

A bit off topic.

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

In what way?

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.

Ah, never knew that. Yeah I definitely want to have an Optisolis that’s violet based and not blue.

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.

I didn’t know that either. On these suggestions I would like to change my Jetusolis order to the 5000K. What do I need to do?
