I have an idea for an addition to your shop: The Osram LE UW Q8WP is basically a bigger version of the popular Osram Black Flat. It reaches the same luminance at maximum current, but is 80% larger, so the resulting hotspot is 80% larger and it produces 80% more lumens. It also does away with the three biggest downsides of the Osram Black Flat:
The central solder pad is now electrically neutral
The solder profile matches that of XP-LEDs (The Black Flat is smaller and doesn't center itself well)
The Vf is much lower
It has a new downside though: the die is not centered on the package. It is shifted slightly in one direction. Can you envision offering a real copper (one piece) dtp-pcb specifically for this LED where the die is in the center of the pcb? This way the LED could be easily centered like other LEDs and we will have brighter ultra throwers!
I think quite a few people would be interested. You could do a poll to get an idea. I would be in for at least 5, maybe up to 10.
That anna makes me trigger happy :heart_eyes:
Especially if Sofirn makes 21700 C8F that accepts MCPCB for it. I can already see 7 Vees with 30T :innocent:
Decided that I need to upgrade my convoy L2.
So just ordered a luxeon V on a MosDTP board together with a LD-B4 (set at 9A) and the ILC-1.
To be honest I forgot the check if the ILC-1 will fit in a L2 (first ‘new’ version, 17mm driver) but should fit right?
Otherwise I will be ordering a S2…
Could you please check brass retaining ring diameter on L2 tailcap? If it's ~19mm, then inner tailcap diameter should be ~18mm, which is the same as C8,S2... and ILC-1 should fit.
The switch board diameter is the same as the convoy C8. The dimensions of the retaining ring are not exactly the same, it’s 20.7mm on the L2 versus 18.8 on the C8.
So it’s a little bit bigger but I think that shouldn’t be a huge problem.
It’s the height that will be a problem not the diameter. You can rig up something to add length to either side of the switch though. You will just need to be a bit more creative since it’s lighted. The washer from the L2 fwd switch is 2-3x as thick as the usual one which the ilc1 replaces
