I received the leds today, 4000k 90CRI
Damn, this thing is so good, the tint makes the cree ashame and can stand next to glorious Nichia
No greenish, not much tint shift
I tested with BLF a6 host, spring bypassed, and hereās the result(lg hg2)
I also have an A6 I plan to install one of these in.
Off topic I know but quick question: Are there any good 5050 LEDās on the market besides the XM-L2? I have a light I want to upgrade the LEDās in but it uses a custom 4x XM-L2 mcpcb that I could not easily replace. I would prefer not use xm-L2ās.
Just installed 3x LH351Ds in my C8F from the last batch and shipments. They look too cold, I knew it at first sight. I've compared the beam against a 30Ā° TIR equipped S2+ using a known good LH351D 4000K CRI90+ from the first set of shipments, I must have received 5000K CRI70+ emitters.
Could you please confirm if possible, AEDe? Thanks.
After a quick glance at 'em they look pretty similar. Will take a shot or two out of their strip packages later. Optics from the above flashlights are completely different, thus the comparison isn't fair. Colors look good but I don't have a known low CRI emitter flashlight :-D at hand now. Got me alarmed, though.
No need for photos, they're definitively orange. In fact just noticed the only unused and not orange looking emitter I have in my cardboard :-D cache emitter box is one of those 5000K CRI90+ XP-G3s (1 out of 46).
The second batch is an L6 chromaticity bin, ā125K cooler than the first (L7). I am impressed by how much a reflector can influence the final perceived tint, beam corona looks yellowish while hotspot and spill are a noticeably cooler white.
Yeah, I got a bunch of lights where the corona is lemon-yellow while the hotspot is also yellowish but not nearly as much, and the spill is blue-white.
Anyone have an idea or guess how the Vf of the 351D 4000K 90CRI emitter compares to the Vf of the 219CT 5000K 90CRI emitter? I put 2 of the Samsung and 2 of the Nichias (from a D4) in a Q8 and visa versa. My impression is that output decreased a little in the D4, but tint, CRI, and throw improved. I don't want to push the Q8 too hard due to the 3 additional cells. I did turbo a bit and detected on no blue tint warning of overheating. I'm not a good judge of output, tint, and CRI by eye though. I'm assuming the CRI didn't actually increase, but it appeared like it did to my eye.
I really like the combo tint and CRI wise, but I don't want to fry one set of emitters due to significantly lower Vf. I really need to setup a heat sink with light tube and test each emitter, but I'm hoping someone in the know already knows.
