A wall of text with overly assertive language and heavy dependence on outside contextā¦ is going to be interpreted as confrontational. Many people wonāt even read the whole comment, and will instead just scan for key phrases here and there to get the gist.
If you can condense a comment into fewer words, and quote the people being replied to or write in a way which doesnāt need quotes, it reduces the chance of misinterpretation.
Anyway, back to the topic, the two emitter types requested are both very highly regarded on BLF:
XP-L HI 3D (~4850K)
LH351D 4000K 90CRI
It would be hard to go wrong with either one, but which one looks better will vary from person to person.
Hmmā¦
I donāt find the 219C 4000K yellow at all, unless you compare it to cooler whites, but thatās a matter of colour temperature.
Must say though, and this makes a lot of difference, i donāt 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 tipā¦
I donāt 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.
Itās more āawakeā than household lighting, but still easy on the eyes / relaxed.
Maybe itās 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 Iāve 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 ā I like more redā ..and of course ā Iām rightā
Jasonww on the other hand likes cool white and doesnāt 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 donāt 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 doesnāt 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 donāt expect any surprises.
But with a next-gen driver and TKās firmware. Which is the attraction for me.
PS:, Iām 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 60Ā° 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 donāt think Iāll loose much output and maybe get even better color rendition? I hope itās not yellow! Lol
Also, I guess Iām lucky I donāt 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 modelā¦ so kinda just waiting on that.
My problem is that I donāt know anyone selling this led on a mcpcb. I can buy the led from MTN E and the mcpcb from led4power, but I canāt put them together (reflow). Do you know of anyone selling this combo?
