which is the most powerful amber/1800k single die?

Flashlight Modding and DIY Parts

as per title, I need to source the brightest amber led I can find.
I can drive it up to 2.5A.
It has to be a single die and 3535 or 5050 because it’s a for a project where the shadows are very precise, and COB for the moment are out as the die is too big.

for the moment I have tried Luxeon Rebel PC amber, Cree xe-G also in amber and an amber nicha 219.
the Cree is the best at the moment but if there is something that has a little more lumens at 2.5A that would be perfect.

does it exist?
or does a 1800k would be more powerful than pc amber?
and in that case do we have a champion of brightness in that color temp?

thanks!!

1800к - ffl351a.
" * at 3,000 mA (official maximum current): 560 lm @ 3.22 V

thanks. I saw that test and that made me wonder if 1800k was a better choice.

Is this led available already soldered to a pcb? On their website it doesn’t look like they do that

They do not solder LEDs on individual boards.

But I think that they will agree to sell the board of the flashlight with these LEDs. Ask them :slight_smile:

I asked them and they only can sell me the 4xled board of their X4…

So probably I’ll buy the die and try to solder it myself on a pcb.

do we know any other options ready to use of 1800k led?

De-domed 2700K 519a is very warm, perhaps not “amber” per say. I’m guessing 2000k?

Depending on your use case, the FFL 1800K might be better becuase of the 95CRI rating. PC Amber is mostly yellow and low CRI so it looks washed out. High CRI 1800K “white” LED is more pleasant for illumination purposes.

2200k.

No :frowning:

I don’t need high CRI, just saturated yellow light…

I’ll try to dedome a 519 I have around, maybe it’s yellow enough!

thank you all for your answers

Can anyone show FFL351A 1800K and CSLNM1.FY side by side? Which colour do you prefer?

From experience, I don’t need a direct comparison (unfortunately I can’t show one either, as I don’t use amber LEDs for reasons other than as indicators in my car).

Amber simply has no real blue component. The data sheets show a very low blue component (especially with phosphor converted or PC Amber), but this is not at all sufficient to display colors even remotely naturally.

everything except orange/red is displayed incorrectly, down to gray, as if the saturation had been set to zero.
This is anything but comfortable for interior lighting, even if Amber nominally has a similar CCT. It’s more like the sodium vapor lamp light we know from streets and train stations…

Here is at least a comparison that shows the differences between a normal warm white 80 CRI LED (dedomt here) and a XP-E2 PC Amber LED. The warmwhite LED has more green and blue in it, which makes the difference in terms of color rendition.

So I cannot recommend any amber LED for something like ambient lighting indoor and outdoor. Just go with FFL351A 1800K and be happy. So far I know these LEDs are the only ones on the market which can deliver this beautiful light with such a high color rendition and quality.

Here you have the spectra of FFL351A 1800 K 95 CRI:
