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?
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
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.
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
It is a very pleasant beam and tint! I guess Luxeons will be, after all, my favourite Leds
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).
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:
