LH351D 2700K 90CRI

Could use some more numbers.

They should be really good for tint mixing and stuff like the BLF Lantern if they end up being able to source the 2700K

Units of current is A or mA . Ah or mAh means charge. (Current 1A go during 1 hour . Please fix.

Thanks for the VERY detailed report! Seems like the 2700K is not all that green. Decent warm white HI CRI on its own but perfect for CCT mixing as pointed out above. 5000K + 2700K will result in a very nice 4000K tint

Agreed, they should not be badly green. I am not a fan of lights warmer than 3000k, but I bet this would mix well with a couple of SST20’s at 4000k.

Time to arrange some group buy for LH351D?
Shipping from US to EU takes over $20 at Mouser. Insane! (do they carry it by themselves?)

we are going to use it in a variable temperature flashlight :nerd_face:

Looks like 351D is taking a big chunk of LED market over SST20 and looks like 219’s…
Or is it just me?

What raw lumens can one expect at 2A or 3A with the LH351D 2700K?

LEd calculator

shaved LH351d 2700k in a Nitecore EX11.2
0.2 to 275 lumens w a fresh 16340
0.02 to 120 lumens with a used CR123 @ 2.88v

nice pinky :slight_smile:

anywhere to buy rather DigiKey ?

their shipping cost is outrageous

Sofirn sells the LH351D as used in the LT1, 2700K and 5000K. They are on their own website under accessories or parts or something like that. Less than $2 each IIRC. $20 gets free shipping

Link to buy LH351D bare emitter, choose 2700K 90CRI or 5000K 90CRI

$1.59 per led, please buy them with other products.

Thanks

will get with bunch other stuff from sofirn soon.

What if I wanted to buy them separately?

Oops. Sorry.

what is that LED?

just ordered a few 2700k LH351d plus a Low/High C01s

That’s the bespoken LH351D 2700K, ordered from Sofirn (WB: “Daylight”)

thanks
I will try one unshaved to see how it compares
I really like the shaved one I got from contactcr… no hint of green

the one you posted, modified for warmer WB and higher saturation, compared to the one I posted…
left not shaved, right shaved

I see slight green in the unshaved…
do you notice it?

and slightly less warm
(I realize the photos are inconclusive, until I can shoot both shaved and unshaved side by side in the same image, at the same output)…

or if someone could point me to the spectrum tests for the 2700k LH351d shaved compared to unshaved…
