Flashaholics only knows how to appreciate 5700K tint. He is not a HI CRI and tint fan and does not have equipment to test light quality. What is special about this headlamp is the ultra hi cri E21A emitters. Maukka already tested each one and his test reports are on Virence.com I also tested the same emitters in my Virence.com modded Tiaras and my results are posted in this thread. The performance of the quad E21A in the H04RC should perform the same since it will use the same beaded optic.
I think that is an inconsiderate thing to say. I know we’ve seen testing of the e21a here. Flashaholics does an excellent job comparing lights to one another and providing a real-world estimate for me from the comfort of my desk. It, along with D_T_A_ and the TLF Bluzie extravaganza, are some of the most valuable beam shots I know of when I am trying to buy a light ‘blind’. I know there has been some talk about tint weirdness. I think it would be pretty valuable to see the quad e21a in action on video, & in a setting that can easily be compared with dozens of other well-known common flashlights/emitters. I think I’d even put some money up for it, either donating a small amount, or buying the lights for myself and shipping them to him first if he was interested (but I do not know of s/h cost from Indonesia to the UK to the USA). A video is a very easy link to point to when the question gets asked, “what is e21a and why do I want one”, and maybe helps promote it to noobs. It is also helpful when we have graciously been offered so many tint customizations. Aside from the e21a caving pictures, I do not believe I’m familiar with many other reviews/comparisons (not including testing, bench style setups, wall beam shots, single pictures, etc.). I would like a quad e21a very much, but would like to know which I would prefer, to maximize my happiness(:
Also, thank you Clemence for another group buy & all the work you put into the CRI hunt and providing a source for people
Well yes, but what I wanted to say is, he already have one with 3500K and if he like warm tint 3000k is not a big step, could try 2700k instead :zipper_mouth_face:
2700K E21A has a low R9 value
I already ordered a 2000K module from Clemence so no need for 2700K.
The 3000K E21A is already a bit rosy by itself by my eyes adapt to it making it neutral so I want something even more rosy.
There is already a 2x2000K+2x3000K in my original post you quoted from.
I just tested the 2x2000K + 2x4000K for you. However, the 4000K is the more recent D240 batch, which has a DUV that is on the BBL instead of below the BBL like the older batch. Also this is installed in reflector lights that normally result in more greenish tint compared to TIR optic or beaded optic. If the same emitter was used in the HO4RC or Tiara with beaded optic, the DUV should be a bit more negative than these results.
The beauty of these headlamps from large manufacturers is the superior buck driver that is much more efficient and much better at regulating output than the typical FET drivers with Anduril we see in the Emisars, Lumintops, Astrolux, Fireflies lights. Unless Lexel has a buck driver with Anduril.
Ahhh, gotcha. Probably wouldn’t want an FET driver with these emitters. Pardon the n00b questions. I just like a ramping interface but I’m sure these will have good mode spacing. Does the H04 driver have a good moonlight?
UPDATE 200129: GB Interest list will be closed on 200201, 00:00 GMT +8
Thanks for all the orders guys, I decided to close the interest list soon so I can start making the lights. Looks like waiting for 200pcs order would be too long. For those still undecided, you guys can get it later via my store.
