Prototype off-road/boating spotlight - King COB!

I’m trying to find someone to help design a more powerful driver and also looking into possibly designing it myself.

On the other hand, there are a lot of cheap “1800w” boost drivers out there from china that could be used if you didn’t want adjustable output or other “features”. I may get one just to play with since I don’t really have any other way to test things portably. I also feel better getting something “rated” for far more than I need given the nature of boost electronics and marketing “ratings”.

Yeah, there’s no way that tiny little radiator would keep 1600w cool. He’s mainly using the thermal mass of the water and the radiator probably just slowly cools it back down after a short run.

I found a cheap 900W boost driver to screw around with as well. I just need more battery!

The white plastic LEDiL “reflector” isn’t much of a reflector as a lot of light actually punches through the plastic.

More of a “diffuser…”

LOL at 2A (11k lm OTF) with the F13402 ANGELINA-W it’s brighter than the street light outside. I really need a way to play with this thing running off batteries. I just moved my power supply to the garage and pointed it out the door. :smiley:

There are a few gaps in the Ideal clamp parts that the reflector clips into which I find annoying.

The giant pin heatsink I got from RapidLEDs is actually bigger than the inside of the battle lantern.

I wouldn’t mind a slightly tighter beam. I need to get an F13401_ANGELINA-M “30degree” since with the big CXB3590 it will actually produce a 54degree beam which I think will yield a bit more margin on me not blinding my wife by accident.

I found the Stratus LED reflector does a good job of making a slightly tighter beam… but it’s not exactly plug and play with the 3590

IIRC, I don’t have room for the Stratus LED reflector in the Battle Lantern.

For the CMA3090, the LEDiL Molly series is interesting. Middle of the road optical efficiency (86-89%) but honestly, nice beam profiles and pretty darn compact.

Looks like I was wrong about Bridgelux VeroSE. Their specs are all over the place depending on which exact LED you’re looking at. I found one that I’m working up a spreadsheet for…

They have some Vero29 series that’ll do 40k lumens at ~250w! Some of the LEDiL reflectors don’t look all too bad either.

C12598_LENINA-M looks pretty decent. With the giant 29mm die some of these reflectors make some really wonky beams.

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.

Under $20… this is the one I got, at that price it’s good to putz around with…

@LouieAtienze, what do you mean your cells can’t keep up at 160W?

4x18650s lights can keep up quite well at 200W, and even higher for 15-20A cells.

Looking at yours again, I much like the mobile app control and LCD display. I may have to get one now when I have more discretionary cash…

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.

I found these on Alibaba… $20 with aluminum housing. The shipping is a bit high, but I ordered a couple anyway 10deg. FWHM

If this works out, it’ll save me a bit of engineering a housing and lens for a reflector…

Looking at their Alibaba page, they have some really cool light modules as well.

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.
