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.

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.
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.
