I think it’s the Mark IV BLF set-up. Been around for ages. Standard practice amongst all good macro people.
Honest
cough
What advantages do you hope to get by using LED lighting? (vs. tungsten)
If accurate color rendering is important for your work, you might be disappointed by the results you get from using even the highest CRI LEDs.
In a remote shoot with no plug-in power, LEDs definitely have some advantages (heat, run time, cost of flashlights).
But if you can plug in to a wall outlet, no LED is going to achieve higher color rendering than a 50¢ incandescent bulb.
If you decide to go the flashlight route, borrow an old school halogen flashlight and compare the results
Or just shoot in RAW and adjust colour balance in post

I admit to doing none of that. All my shots are simply adjusted with whatever White Balance setting is needed during shooting.
That’s if it is needed anyway, and half the time I don’t think it is. I must have a colourblind camera, :laughing:
You cant photoshop CRI on a non CRI light source
White balance cant fix it, a CRI light wih more red illuminates only red parts, more amber, cyan also come in play with high CRI light source the same way
I was about to mention that. You beat me to it.
This is absolutely not an area that I know anything but Great Thread!!
Maukka gave a good idea on thos “Viltrox”, I know exactly who would need just these :+1:
Hi. I have the same question. I want a good high cri flashlight but in a small compact edc form. What I have found so far is an upcoming flashlight which according to specs is not only high cri, compact and and reasonably priced but also high lumins considering it’s 90+ cut.
WUBEN T046R 1300lumims
It has 3 XPG3 less which I was concerned about but after some research I found out that recently they have indeed released a high cri version of this led. Though it has slightly greener tint rather then the radish tint of the HIGH IS 219B. Would anyone suggest a similar flashlight to this one? Or is this a good option in it opinions.
If someone can suggest other similar high CRI COMPACT FLASHLIGHTS I WOULD appreciate it really.
Nichia versions of Jaxman E2 and E2L.
Astrolux S41 has Nichia 219 high CRI option
Emisar D4 also has Nichia 219 option.
I see you have a Convoy S2+
If you want you could contact kiriba-ru on this forum and he can send you an assembly for the S2+ that uses 3×219C 4000K leds on KD board with KD optics. The whole assembly including the pill is a drop-in module - all you need is a pair of needlenose pliers or heavy duty tweezers to change the optics out. Cheaper than a new light.
Bush cricket in bright sunlight from today using the three lights - colour seems good to me 
Beautiful
Where did I mention CRI ??
LEDs as of now do not have 100% CRI (for that you would have to use a strobe) but they do need to be white balanced.
Cheers David
Great capture with the bush cricket DrHook59
Sorry, last leds went to your friend from England - such assemples are not available anymore.
Oh no! I shall have to hope nothing ever goes wrong with mine then! I LOVE my triple you made for me. I’ve been putting it to good use for all sorts of things, including photography - it does burn through a 18350 in turbo, though!!
@Stephenk Thanks first of all. I have searched the jaxman e2 and e2l. E2 has much is 219b but only 350 lumins. E2l has
Has quiet a lot more lumin but so far as I can tell only xpg2 led. Not sure if it has high cri.
@lexel i did know about the astrolux. But I prefer s42. Which one do u recommend? Nichia 219b in s41 or nichia 219c in s42?
@drhook59 the new pill would have definitely been a great option. Sadly no more left :(.
And how about the queen t046r?
Go with the high CRI (90+ 219C) version of the Emisar D4 instead, it’s a better light.
(I have several of all 3 (S41, S42 and D4).)
