[Optisolis/E17A/E21A] Jetbeam Jet-µ

I voted E17A/21A If its a lower powered aaa I want throw. And I don’t even know what they are. I am just going off djozz post.

I’ve never actually attempted to use a PIC MCU. Tterev3 published some example code for the PIC10F322 though.

For now, the next MCUs I’m looking at are AVR models with more than 8 pins. But after I get the hardware abstraction layer written for those, maybe it’d also be feasible to add back ends for PIC models.

This obviously.

I voted for the E21A because I have tunnel vision, so a tight beam is normally more useful to me. What’s the tightest optic for this LED? 5° or 10° would be nice :slight_smile:

What will “slow beacon” correspond to? I like 0.5Hz to 1Hz, at 50% duty cycle. Tunnel vision again - it’s very easy for me to miss short, infrequent flashes. A brief flash once every 5 seconds - call it 0.2Hz at 5% duty cycle - would be useless to me, for example.

While I would be very happy to see an 5000K Optisolis and a 3500K Optisolis variant, beam versatility as a selling point made me chose E21A/E17A. I’d settle for a fine beaded optics with 15-20° beam diameter.

Phosphor converted color LEDs are also seem to be a good feature for E17A in my understanding.

For white LEDs, I’d choose 3000 or 3500K CCT for warm white option, and 4500K CCT for neutral white.

I think, output levels would be best like this: 0.5 lm - 4 lm - 25 lm - 100 lm.

I don’t know your possibilities, but if you could arrange a single AA EDC as well, I think, that would be also very good. (Single AA could be a better match with a single E21A emitter in term of max. recommended power level)

I would buy AA too.

nothing to add here, AA as EDC is just perfect

Anyone with PIC programming experience here? With reprogramming kit, we can adjust whatever modes we want. The limit is only max current (230 - 250mA). I wanted to bump a bit more to 350mA but that would be unpractical with small capacity AAA NiMh and could easily fry the E17A with 10440. It can take 10440 for under a minute in max before gets very hot (both the driver and the LED), hence no recommendation.

That’s it E17A/E21A wins! Thanks for all the feedback =)

I voted E21A. I’m not a big fan of twisties and AAA lights. I already have a bunch including Skylumen E01vn with 3200k 90CRI yuji emitter. I like clickies and AA. But since it is from Clemence, I will be buying it regardless.

3000k E21A would be my ideal for AAA sized lights :wink:

Goggle “yellow gap”. Monochromatic LEDs can be pretty efficient in red, green, especially blue, but yellow/amber is pretty dismal efficiency.

PCA LEDs take a shorter-wavelength blue (sometimes violet?) LED and convert that to yellow/amber more efficiently than a regular monochromatic y/a LED.

I always wondered but never really found out definitively the spectral spread of PCA LEDs. Monochromatic might be a nice narrow spectrum if that’s what you need, but PCA for a wider spread (eg, everything from orange to yellow-green but a peak/dominant wavelength in the yellow/amber range).

I’ve only tried some Cree color LEDs, like XP-E2 and XQ-E… but they make nice vivid colors. The quad XQ-E RAGB setup I made for my lightsaber gives me a pretty vivid spectrum for everything except purple. I didn’t get red enough red emitters or blue enough blue emitters to make a good purple.

So, you need deep blue and far red, but you got “regular” blue and red? But other than that, it’s working fairly well? Do you have the firmware finished yet (or close to finished)? I can’t remember if you’ve mentioned it.

Sorry, this was kind of a tangent which barely relates to the thread topic. Was mostly just saying that the color emitters work pretty well, though some shades need relatively specific components — like photo red and royal blue instead of regular red and blue.

About the saber project, I haven’t done much with it lately. I need to make a new PCB, but before that I need to learn how. And the code needs to be rearranged to enable a higher frame rate, because 60fps looks weird on a fast-moving object. Could also really stand to be ported to tiny841 in order to get the 4th PWM channel working better. But I’ve been busy with other projects instead.

I’m not really sure why color emitters were relevant for this thread, except that the MCPCB may be compatible with some color emitters. But color isn’t really the point of the AAA EDC project.

Color emitters is not relevant to most of us but it is an additional option since color E17A can use the same footprint as E21A. Especially when the beacon 4th mode can be added as planned. Green beacon is very eye catching from afar.
Last night I tested the stock board and at only 230mA the OEM non DTP board perform OK, with very minimal temp sag. This is a good thing for cost reduction but could be a deal breaker for those who plan to put 10440 in it.

Thanks for being cool clemence. :sunglasses:

Sorry for the off-topic about color LEDs. I can’t remember what I voted now, so I will go ahead and cancel my vote, whatever it is, and make it for the E17A/E21A choice. So, my vote might be changing, or it might be staying the same. We’ll see. :stuck_out_tongue:

Friends,

Couldn’t decide myself. So I made both version: the Optisolis and E17A/E21A.
The prototyping is done with better result than expected. Looks like months of various TIR optic shopping is now paid off. Optisolis is finally flashlight enabled with correct TIR optic. This is the pickiest LED I’ve known so far. No reflector, no plain TIR optics, even the micro lensed (peebled) TIR optics choices are limited to only few. While wide angle optics be it reflector or TIR will fix the ugly beam issue, to get usable beam angle narrower than 30° is quite a challenge.
I haven’t test the E21A version as it will be so much easier. Let’s take a look at below pics and video:

Quick test at white wall (Optisolis and 30° Microlensed TIR optic).

Stay tune for more test results!

EDIT: forgot to include the output
Preliminary test result using sm505 P9 Optisolis:
OEM Cree XPE2 [unknown bin and CRI]: 96lm - 18lm - 1,3lm (advertised as 135lm max.) :neutral_face:

  • some artifacts (stock TIR optic)

Optisolis [p9 rfa00]: 65lm - 13lm - 0,9lm

  • limited to 30° micro lensed TIR optic only, the rest cast ugly unusable beam

E21A [D240 sm653 R9080]: 65lm - 14lm - 1lm

- very throwy, the hotspot is only half XPE2

  • super nice beam without visible tint shift and no artifacts (stock TIR optic)

It’s interesting that at 230mA, the efficiency of Optisolis matched E21A R9080 very closely

Looking forward to the final options!

Perfectly regulated, efficient, and best Tint and CRI, what is there not to love??

Superb! Can’t wait to get one of those Optisolis EDCs. Or maybe a 2000K E21A, or both…
