That is cool… But I’m having a hard time getiing 160W with batteries!!! For a wired light however that seems pretty good.
What I find amazing is how tight the beam can supposedly be with some COBs. Yeah with some of the larger comes it would seem they’d make a donut hole at enough distance. Or more likely that using the base, the COB is not optimally focused with the reflector.
Well, I’d like the boost converter to run somewhat efficiently, and I don’t know if I want to spend any more cash for decent 18650s… Especially when I have all these LiPos sitting around from my DIY drone days (which really was not that long ago hehehe.) Maybe not too bad for a 36V COB, but for 48V @ 3.6A I’m not so sure how efficient the boost converter will be working then - I could be wrong. The other thing is capacity - I have 5200mAh, 7500mAh LiPos already. I just don’t want to spend too much more than necessary on this project, so trying to work with what I have. I also don’t want to kill my good 18650s - I save those for my flashlights. These could be handheld, but I would consider them to me more of a “portable outdoor lighting solution” that I can run on max for more than a few minutes. Unless you happen to know of an LED boost driver that will work. I have a TaskLED HyperBoost, and I’ve seen Matt VoB light a 3590 in a GT with it, but he used 8 18650s in series by modding the carriers from parallel to series.
That’s pretty darn cool if I’m reading this right.
I need to figure out how to post images here. I got a mechanical model for the LEDiL Angelina reflectors so I’ve been plugging away at drawing the required custom components.
I have problems too… I try the “insert image” tool above the comments box, put the URL in, and nothing shows up. So I’ve just been linking to my Google Photos (my Flickr account is almost full.)
I’m pretty curious to see if their 10deg. FWHM claims are true, but if it’s anywhere near 20-30deg. I’ll be a happy camper. Would like to see your drawings if you can link them.
I’ve tried a million times, but the images do not appear. Maybe you can take one of the links I posted above, and post the image, so I can see how it is done? Am I missing something?
Yeah, I pulled out a pile of old 18650s that I have last night and realized I could probably fit 12s2p inside it with that little LEDiL reflector if I wanted to. Though, I’m actually thinking about using 3s 18650 battery holders for maintenance reasons. (3s are the largest I’ve found to date) I’d like to put a balance connector and charge connectors as well on it but I’m not quite sure how to do that safely.
