CSLNM1.F1+LEDiL SEANNA Build (1.8KM+)

I finished up this custom 3D printed thrower build I have been working on for a while, it actually surprised the heck out of me what a little osram chip and a seanna can do:

I got the LED aligned properly with the help of a 3D printed tool and some thermal adhesive so it stays in place once I remove the tool (after letting the glue bond of course)



I used a driver that can be found on amazon and ebay which utilizes the LTC3870 buck boost IC, which worked well. I am however working on my own set of custom drivers with some cool features.

Pretty cool what can be done with fairly inexpensive parts (except the seanna of course), I got this thing fully built in about 4 days including 3D print time, the LED chip itself was about $4 on mouser and I got a MCPCB for it for $1, I reflow soldered the led on to the board and it was ready to go, all that’s left was designing the 3D printed parts and putting it together with the lens, driver, and air cooler.

By the way I just used a power bank with PD capability for this thing, I also had to use a PD trigger so I can get the correct voltage out of it.

Sweet, I love builds like this. Nice job though I have to say it looks like it’s in need of a handle :sunglasses:

Just curious, why green?

I actually had a handle all CAD’d out and ready to print for it but I just completely forgot to print it out because I was too obsessed with the light itself lol:
I did green because it gives the highest lumen output by far of all the osram CSL series chips, also the color green is the brightest color based on the human eye wavelength response curve

Awesome build. How much did you drive it at?

The funny thing is CSLNM1.F1 looks white compared to a monochromatic green like XP-E2 , it’s perfect usable as it doesn’t wash out other colors.

excellent build, thanks for showing it to us!

I drove the chip at 6.5A which corresponds with it’s peak output as demonstrated by the djozz test: https://budgetlightforum.com/t/-/56233
