+1 for 4000K Luxeon V

Luxeon V2 5000K >>> Luxeon V 4000K >>> Luxeon V2 3000K

You gotta love these leds :smiley:

Thank you for the answer, led4power. :slight_smile:

I’m sure tint mixing with 3000K and 5700K would look great. Recently I did a lot of tint mixing in multiple led flashlights. But the 4000K Luxeon V would still be needed for single led flashlights.

Neven,
I’m thinking about modding a C8 with one of my UV leds. They run upto 3A @ 4.8V.
Would an LD-A4 be a good fit for running the emitter at full power from a single decent 18650?

Wow. Those tints do look great. Hmmm…

UV LEDs generally (especially <385nm) have very high Vf so linear drivers are not good fit for that purpose.

Thanks. I’ve apparently missed that this driver was a linear driver. Revisiting the product page and the PDF i can clearly see it now. Even the name suggested that :smiley:
I guess I will have to find a boost driver.

Boost is not good too,you'll need buck-boost since LED voltage can be lower than full battery (4.2V). Other option is to use two cells in series (18350/CR123) + linear or buck driver.

Thanks alot. I don’t want to hijack your thread, but can you point me towards some good drivers? A single mode full power boost driver would be okay

It's best for you to open new thread, some BLF members are better informed regarding Chinese boost drivers.

They are indeed!
The ones I like the most are the 4000K Luxeon and the 3000K Luxeon V2. Actually I am thinking about getting a triple of 3000K of these :wink:
It is a very pleasant beam and tint! I guess Luxeons will be, after all, my favourite Leds :blush:

Osram CSLPM1.TG (aka white flat 2) is now available in higher 6P flux bin, that should be about 10% brightness increase compared to 5P (according to datasheet and previous measurements - about 1800lm @ 7.5Amp):

16mm DTP boards are out of stock, new batch of gen2 boards are expected by the end of March ( about 1.5 month later than planned because of virus thing).

Neven what about CULNM1.TG restocking?

Where can i find gaskets for the 4040 CULNM1.TG ?

I'm not sure about CULNM1.TG restocking, I will try to source some.

There are no gaskets currently available for 4040.

And ask for the culpm1 as well? :innocent:

I'll try.

Luxeon V 4000K is in stock again, CAT code is V13F (same Vf bin as 5700K so they can be mixed), mixing 4000K+5700K is added as option for all 4x and 6x boards:

Perfect, thank you. :+1: :sunglasses:

Neven,
I hope you are doing well. Any update on the 3030 4x 20mm boards?
