2000k flashlight

nice! just ordered fw3a too and will put the sst20 2700K in it too. seems like that’s the lowest cct and highest CRI option we have for a 3535 footprint

Pretty much. My example of the 2500K Osram Oslon had a higher CCT then the 2700K SST-20 95 CRI as did the 2200K XT-E.

Have you tried dedoming the sst20 2700K? that might make it warmer maybe?

When Clemence will be less busy with his city light project, he will make a triple MCPCB for Nichia E21A (lowest CCT 2000K but R9050)

The E21A 2000k has been verified many times to be 9080

fw3a with E21A would be amazing. can’t wait.

yeah i think maukka measured the e21a 2000K with an R9 of 98

You could try the Lee zircon amber filters to get even lower cct.

The measurent was in the hotspot on high setting. The Mi1C does have a AR-coated lens that may have affected tint a bit.

Djozz which emitter did you measure?

i’m assuming that’s an E21A in 2000K. looks like it to me. what flashlight and mcpcb is that?

I did not know that I posted a quiz :slight_smile:

The light is a Klarus Mi1C in copper, the led an E21A 2000K R9050, bought from Clemence. But it behaves like a R9080.

People are on about “look at how candle-like this 3000K XP-L HI is” with their Anduril lights, but the Copper FW3A, Anduril Candle Mode, and finally candle colored 2000K LEDs…yes the actual copper candle. :sunglasses: Not to bash on Djozz

Samsung offers LM302Z+ mid power LED with CCT down to 1800K. CRI80 only.
Not that it’s some great option but that’s an option. Clemence sells compatible MCPCBs.

Another 2000K option:
Nichia NF2W757GT-V3F1 is another 2000K CRI80.

Just discovered on AE this

Ok, it looks like cheap chinese no-name LED. But what do you guys think? Does it deserve an attention?

I stumbled upon 1800K Luxeon Z ES:

Note that according to Lumileds datasheet such warm CCT is not available. So it may be a fake LED - but possibly still not a bad one. Especially considering that there’s little competition in that warm end of the high-power LED market.

It’s a good sign if people ask quality very warmer lights.
because market lacks,untill there is low demand.
But it’s important not going on Infrared ahah

Not sure why you’d want a light throwing 2000k…
But have you considered filters?

I would never get any leds under 2700k that are not hi cri and does not have a high R9 value. At this level of warmness, color rendering will look like amber light or high pressure sodium light. You can’t really make out the colors. With an ultra high CRI LED like the E21A 2000k, I can still clearly make out all the colors. In fact, when my eyes are adapted to the color temp, everything just looks real good with the E21A and I don’t even notice the yellowness anymore.
