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 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.
