Hmm…
I don’t find the 219C 4000K yellow at all, unless you compare it to cooler whites, but that’s a matter of colour temperature.
Must say though, and this makes a lot of difference, i don’t have any 4000K 219C in a reflector light.
I tried one in a C8 at the time and it was very disappointing. A lot of tint shift and thus a dirty brown corona with a green hue.
You can avoid tint shift quite a bit by using a tall centring gasket that shrouds the LED a little.
Paint it white with White Out (Tipp Ex) and the green hue brown mixes with the more red hue cooler white of the spill.
The green hue brown will no longer be in the corona, in fact, there is much less of a corona (depending on how much is shrouded).
I did an XM-L2 4D and a 219C 3000K like that, and also a Samsung LH351 in reflector lights.
Just an off topic tip…
I don’t know any regular 5mm through hole white LEDs that are nice.
Their tint and CRI, let alone the amount of red make any Cree of the same color temp look nice.
I personally prefer 4000K for work lights.
It’s more “awake” than household lighting, but still easy on the eyes / relaxed.
Maybe it’s the big blue spike in the average LED spectrum that makes me prefer something warmer than 5000K.
I like it too.
I think most people prefer LEDs below the BBL
But i never experienced the 219C 4000K as being greenish, except, as i mentioned, in a reflector light.
One of the best things I’ve done over the years is to be aware of people who like lights that you like and treat them like a bit of a mentor . I started doing this a long time ago and have followed Toykeeper since we both care about similar things in a light . I even know her preferance in tint vs mine “ I like more red” ..and of course “ I’m right”
Jasonww on the other hand likes cool white and doesn’t notice low pwm .. both of which make me crazy.
When someone simply says TK likes it I have a pretty clear idea what it means.
I used to like cool white but as my eyes have aged anything much above 4000k has too much glare and has become increasingly uncomfortable to use. So I agree with TK that preferences, literally, have a lot to do with our individual eyesight
I do not like rosy in an EDC light. I enjoy it in an trail hiking camping type light. But not anywhere there might be white.
Of course this is just my opinion
Many individuals possessing a Y chromosome may have some degree of abnormality, even if they don’t know it. Which is why, when choosing colourful things, it is always best to also consult someone with two X chromosomes.
The odd thing is that this doesn’t seem to translate to painting, or fashion design, or cinematography and colour-ism, where the XYs historically totally dominated. But that is changing. Rapidly.
I think I have pretty good colour vision,
Edit: despite being mostly a blue-eyed blonde Angle. With a big dose of Scandinavian.
But I expect my corneas are ageing, and my retinas getting a bit frazzled (though my eyes have been protected from UV all my life, due to wearing suitable glasses for my short sight, specified by my uncle, a very senior eye-surgeon.)
As for use in very low modes, where only the rods are working, not the cones, it is moot.
Back to the point, as TK has said, this is just another triple with a http://www.carclo.co.uk optic. (A great British company by the way, within spitting distance of me). Dressed up in a fancy looking suit that might be durable.So don’t expect any surprises.
But with a next-gen driver and TK’s firmware. Which is the attraction for me.
PS:, I’m trying to limit myself to 1 post per day. And avoid grumpiness, as far as possible.
My previous experience with very yellow NW lights has put me off from them. I have come to find 5700K is okay (xhp70.2 and xpl).
I put a Nichia 219C D280 80+ CRI 5000K behind a 60° pebbled TIR in a headlamp and really like it. Except for the lower output. For headlamp use I need good color rendition. I sometimes have to identify wire colors in automotive use where CW is not the best choice. I might try a SAMSUNG LH351D 4000K 90CRI LED in a headlamp. I don’t think I’ll loose much output and maybe get even better color rendition? I hope it’s not yellow! Lol
Also, I guess I’m lucky I don’t notice PWM. :partying_face:
I have yet to find anyone on BLF with my particular preferences.
About the FW3A, mostly just waiting still. I hear Lumintop wants to adjust a part by half a millimeter, and needs Fritz to update the CAD model… so kinda just waiting on that.
My problem is that I don’t know anyone selling this led on a mcpcb. I can buy the led from MTN E and the mcpcb from led4power, but I can’t put them together (reflow). Do you know of anyone selling this combo?
Arrow sells 5000K 90 CRI. They don’t sell it on an MCPCB though. It does work on XP/219 size MCPCBs.
I’m not sure what to suggest other than learning to reflow. It does not take a great deal of skill or special equipment. Here’s a demo of reflow with a lighter. If you’re concerned about breaking stuff, Arrow has cheap LH351Bs and you can test for functionality using a lithium button cell and a couple wires.
