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?

Due to current situation, those boards will not be available for some time, 16mm 3030 DTP are back in stock, next are 3030,3535,4040 20mm Cu DTPs and 3535,4040 16mm Cu DTPs.

Thanks for the update Neven.

Are there any plans for 20mm triple 3030 MCPCB?

Same answer as in post 1291.

Will you be selling SBT90.2?

Depends on interest, but it's an expensive LED, additional problem is custom DTP PCBs have to be made and those have large min. order quantity, so I'm not sure it's feasible.

If you would just sell the bare led, people could buy the 20mm DTP SST-90 board from kaidomain. But I know that your policy is to always offer the option of the led reflowed on a board.
