OK, I’m ready to take orders. Below is the output and partial runtime using 3500K D220 R9080 E21A. More thorough test by Maukka, check HERE.

Here’s what you get outside the normal OEM accessory:
  • 16mm medium microlensed TIR optic
  • 16mm medium-wide microlensed TIR optic (default)
  • 16mm wide microlensed TIR optic
  • 16mm oval microlensed TIR optic
  • Quadtrix E17A/E21A LED module (installed)

Features:

  • Very high CRI of R9080 minimum guaranteed (For all CW and WW E17A and E21A, except for 2200K which is R9050 minimum)
  • Available in wide variety of CCT: 2000K, 2200K, 2700K, 3000K, 3500K, 4000K, 4500K, 5000K, 5700K, and 6500K. All in very high CRI.
  • Sensible, fully regulated, and dependable output levels
  • Longer regulated runtime
  • Due to very low forward voltage of Nichia E series, combined with 4P setup, this headlamp works with almost any 18650. No high drain battery needed to get max output.
  • Highest mode can be restarted multiple times with very little output reduction in each succession. OEM LED suffers heavy output reduction with multiple highest mode restart.
  • Four different optics to choose included
  • Better reliability and consistent performance with two mounting screws for the MCPCB. Threads are deep and roll formed.

Out the front output with 3500K D220 R9080 E21A using widest optic:

  • Mode 1: 0,19lm
  • Mode 2: 2,16lm
  • Mode 3: 8,95lm
  • Mode 4: 30,13lm
  • Mode 5: 65,92lm
  • Mode 6: 174,64lm
  • Mode 7: 256,52lm
  • Mode 8: 562,26lm (2 minutes step down to mode 7)

With OEM XML2, the highest mode behaves like direct driven (unregulated), the output follows the battery voltage. After each step down, max output restart will be significantly lower. With E21A you can have multiple max mode restarts with same max output.

Price: $75 ($60 including worldwide free shipping for 25 first buyers)
Click THIS link and add your order as comment there. Don’t try to edit the Gsheet, it’s locked. You can only add comment, I will edit the list accordingly.

25 ,26 first order will be ranked according to the received payment date. Paypal the payment to: clemenceronald@gmail.com

Order will be placed to Skilhunt as soon as 200pcs order reached they’re back operational (almost all factories extend their holiday due to corona virus outbreaks).

Regards,
Clemence

I’m still away from my PC. Some were late to get the discount. To make it simpler, I’ll refund those payments.

I just ordered 4 of the H04RC. Clemence modded lights are always top quality and these E21A emitters are simply delicious! I use the Tiara Pros quad E21As every day and they are simply fantastic.

 

I own a bunch of the older Virence modded Tiara Pro with quad E21A and I use them on a daily basis. They E21A combinations produce some of the best looking tints I've ever seen and I own literally HUNDREDS of flashlights. Also the blue light output from this emitter is very low making it perfect for use as a pre sleep light or bathroom trip light as it will minimize suppression of melatonin. The 2000k version actual produces significantly less blue light than incandescent bulbs yet produces 9090 color rendering. 

Don't be misled by the 500+ lumen max mode. I almost never use the max mode because it is actually more than enough light for any indoor use case even though I'm a fan of ultra bright flashlights. These are meant as practical tools with regulated sustainable output not FET driver lumen toys. In fact I rarely use the 200+ lumen mode because it is too bright. I normally use them with the sub 10 lumen modes because at night with dark adapted eyes, even 50 lumens can be disturbingly bright. 

Here are measurements I performed on the Virence Tiara Pros w/ E21A quadtrix using the Texas Ace Lumen Tube calibrated with Maukka lights and Sekonic C-800-U spectrometer. The H04RC should be very similar.

Tiara C1 Pro 2000K Max Mode 393 lumens 2009K -0.0001 DUV 95.6 CRI Blue light relative amplitude 0.07 90.8 R9 87.5 R12 95 Rf 101 Rg  NCR18650GA
Tiara C1 Pro 2x2000K + 2x2700K Max Mode 494 lumens 2319K -0.0016 DUV 96.1 CRI Blue light relative amplitude 0.17 97.9 R9 90.2 R12 95 Rf 104 Rg  NCR18650GA
Tiara C1 Pro 2x2000K + 2x3000K Max Mode 505 lumens 2442K -0.0034 DUV 95.3 CRI Blue light relative amplitude 0.23 96.0 R9 88.3 R12 94 Rf 105 Rg  NCR18650GA
Tiara C1 Pro 1x2000K + 3x3000K Max Mode 428 lumens 2577K -0.0076 DUV 94.5 CRI Blue light relative amplitude 0.36 94.5 R9 84.5 R12 93 Rf 107 Rg  NCR18650GA
Tiara C1 Pro 3000K Max Mode 522 lumens 3064K -0.0027 DUV 96.2 CRI Blue light relative amplitude 0.44 90.9 R9 90.5 R12 95 Rf 104 Rg  NCR18650GA
Tiara C1 Pro 2x3000K + 2x4000K Max Mode 524 lumens 3378K -0.0039 DUV 96.0 CRI Blue light relative amplitude 0.63 87.9 R9 87.6 R12 95 Rf 104 Rg  NCR18650GA
Tiara C1 Pro 4000K (D220 batch) Max Mode 543 lumens 4162K -0.0051 DUV 96.3 CRI Blue light relative amplitude 1.00 87.1 R9 81.0 R12 93 Rf 103 Rg  NCR18650GA


Note: All of my Tiaras use the 60deg wide flood optics. Also keep in mind these are real lumens. 100 lumens here is equivalent to 120-130 Zebralight, Acebeam, Thrunite, Skilhunt, etc. lumens. Clemence lumen should be the same as mine since he has Maukka calibration lights.

I’d love to see e21a tint/beam pictures by people who own them. I’m trying to get a feel for tint & brightness in the real world

Use lower modes and CRI Rnn E21A (lower than CRI70). It will be brighter than stock XML2 and has extra 30 minutes longer run time.

Don’t worry about tint with e21a. Pretty much all of the e21a LED’s that Clemence sells are right on the BBL line or even slightly below, for perfect tint. Just pick your favourite CCT. There won’t be any green in these LEDs. The color rendering is also absolutely amazing, and unlike SST20 leds’, they don’t go green when using them at lower power.

As for beamshots, that will always depend on the combination of LED and optic used. If you are looking for more throw, go for the quad e17a, and if you want better efficiency and floodier, go with quad e21a.

Here is an example of a Fenix HL50 I had modded with single e21a LED vs the original XM-L2 LED. You can see the improvement in tint is drastic! No more Green!

I have a Tiara modded e21a, and placed an order for the Skilhunt that will be a nice complement with longer battery life.

Also placed order on Virence H04. I already have a H04F with a single 3500K and I like it despite the quirky diffuser thingy. Same threads as the H03 so S1 shorty tube also works if you can get the right one. Also like the Mode B UI. Add/remove levels as you like. I have mine set to all levels except T2 since its almost the same visually as H1. It’s also easy enough to add/remove levels when necessary.

I can see them, but the URL is pretty long so I'm not surprised some cannot see them.

If you can solder, H04RC is unlike ZL or AT, it’s very mod friendly. You can simply swap the LED modules later.

Ah, I didn’t think of that. Would I be able to have the spare emitters be shipped with this purchase?

Yes, price is $10 for each additional quadtrix E21A LED module, and $8 for each quadtrix E17A.

You’re more than welcome. I should’ve worked with Skilhunt before, they’re more flexible than the other company. This mod is driven by popular demand.

Is the 75$ with shipping included ? the crossed out ($60 including worldwide free shipping for 25 first buyers) makes it a bit ambiguous.

Looks like I missed out on the early bird as well Sad

Can someone kindly catch me up on E17A vs E21A? e.g. is there much difference in beam profile / throw, runtimes etc.

Roughly:

The E21 has an XP-G / 219C size die, and the E17 has half the mm² surface area die of the E21, so E17 is comparable with XP-E die size.

The E21 can safely handle max. 2 Amperes and the E17 can safely handle max. 1 Ampere.

So a quad of E21 can handle 8 Amperes and a quad of E17 can handle 4 Amperes.

So i think a quad of E17 would be more than enough to handle the power of the H04.

A quad of E17 is also much smaller so it will be less floody (tighter beam) and probably have less ‘donut hole’ effect.

But the donut will be evened out by the optics anyway (i assume)

Probably the E21 quad will have better efficiency because they will have an easy job, below half of their maximum recommended current.

But they cost twice as much as the E17, but the LED boards for both are equally priced and not cheap, so for the total price of this modded Skilhunt, the difference is negligible.

The driver of the light will determine the current and thus the run time, wich will be about the same, but maybe a bit longer for the E21 because it will work on a slightly lower Vf because they run at less than half the max. recommended current.

So in all, it seems the quad E21 is the most attractive option for buying this light.
