[GB ended,discussion only] CRI > 80+ NICHIA 2000K-6500K [E21A/219B/219C/319A/144A/757GT-F1(Optisolis)]

VR38SP16 will be insane! Gonna get some of your new creations from you for sure.

Do you know, what host(s) and optics support that board? :slight_smile:

So far I found Jaxman X6 (XHP70.2) is decent host for it

Awesome! Tint mixing+color is first thought but there has to be a ton more ideas this would bring.

Very nice! That is a really great range of options!

What’s the flux bin of the sm353 and sm403?

sm203 D160 R9080
sm223 D180 R9080
sm273 D200 R9080
sm303 D200 R9080
sm353 D220 R9080
sm403 D240 R9080 (old stock)
sm453 D220 R9080
sm503 D240 R9080
sm573 D240 R9080
sm653 D240 R9080

I hope somebody will be able to produce a ‘soda can’ build with this :slight_smile:
(but maybe Jaxman X6 is more suitable to produce higher sustained output)

I have my eye on a specific light to be used as a host. Waiting patiently for this board to be for sale :slight_smile:

no thanks, it may look natural and be slightly brighter but it’s too green in my opinion.

But mixing 2*sm353 with 2*sm453 should result in a nice 4000K with a rosy tint.

The E21A D220 definitely have a much nicer rosier tint than the D240 version. But the D240 measures 15% brighter in my lumen tube.

If one wants lumens he shouldn’t buy a E21A custom in the first place. The D240 looks very natural in the higher modes but that’s it, in the lower and low-medium modes the tint is bad and unacceptable, 15% more output doesn’t make than any less of an issue. Even the 80CRI XPL-HI 5D with a slightly rosy duv of about –0,0020 makes the D240 E21A look green at about any level.

I agree with you, I like my 4xE21A 4000k D220 Tiara Pro more than my 4xE21A 4000k D240 Tiara Pro. The D220 version looks nearly identical in tint to the 219B 4000k 9080 that Clemence was selling.

Guess I’ll wait a while till Clemence restocks the D220 bin.
Is your D220 4000K (and 4500K?) Tiara below the BBL on all levels?
Interesting you have two identical lights with a different flux bin :slight_smile:

I don’t have the equipment to measure but my Tiara with D220 4000k looks a bit below BBL at very low output and goes down to very nice rosy tint at high output much like the Cree 5A/5D tint. The D240 doesn’t look bad by any means. It is nowhere near as green as the 219C 4000k 90CRI, LH351D 4000k 90CRI, or SST-20-W 95CRI FB4 tint. Just not as nice as the E21A 4000k D220 or 219B 4000k 9080 tint that Clemence was selling.

This apply not only to Nichia. Almost all LEDs with top bin at their particular category tend to be greener than their lower bin counterparts. Maukka also confirm this. Higher flux bin = more chance to land on green zone.
Light flux measuring devices adjusted to human eyes sensitivity. Our eyes sensitivity peaks approximately in the green zone.
Fortunately, E21A gets more rosy as the current goes up. D240K 4000K has mild greeness at very low current (< 50mA). Makes it unsuitable for pink tit snob who often use it at sublumen level.
With this findings, I will only place any order a step below max flux bin for green free measures.
For example: max flux bin for 5000K - 6500K is D260, I ordered D240 for these CCTs.

Tu put it straight, according to the owners the light sucks below the main3 mode (~300lm). And they are certainly not tint-snobs, just OEM and Emisar users.

However my 3500K mix is magical and the 3000K rocks as well. Overall I think your Wizard/Tiara PRO (with mixed or D220 CCT’s) are the best multi-purpose headlamps ever made.

:+1:

I also mention E21A 4500K D220. It is (probably) the most crispy neutral white tint I have ever seen. Under 500mA per LED it gets a very slight hint of brownish yellow (which is fully acceptable for me anyway). The sweet spot for tint is around 800-1400mA per LED, above that it gets into a bit of too rosy tint for me.

UPDATE 190312:
Store restocked with complete selection of R9050/9080 E21A as follows: 2000K, 2200K(new), 2700K(new), 3000K, 3500K(new), 4000K, 4500K, 5000K, 5700K(new), 6500K. Same 3 steps MacAdam as usual.

Hi Clemence, I think you would like to see a test of a SunLike led: SunLike 3500K 95+ CRI midpower led from Seoul Semiconductors tested
