Prototype off-road/boating spotlight - King COB!

Well, you could just run a 20AWG wire across the contacts, that will give you enough current capability no problem.

Sounds cool… Thanks again for the input!

Dudeguy confirmed for me a while back that the hyperboost could handle 12s.

I have two HyperBoosts. As of yet untested. But I like that a 50k pot can be wired directly to it for dimming - which is an important feature for me. I don’t need full tilt all the time, but it’s good to have.

With my test rig, I found that the Vero29 will produce light even at around .06A. Pretty cool.

I think if I can get my hands on an extension tube for my Convoy L6, I’m going to put a Vero29 in it. I’ll have to cut down a Lenina to fit in the head but it would be brighter than any other L6, probably cheaper than my 21x LH351D concept and more unique.

Would be cool to see this; have been thinking along similar lines as well, though not sure what the balance would be between runtime and output…

I’m still missing some dimensions and models but I suspect a Vero29 won’t fit but I think I could make a V22 work with a LEDiL FN14637_OLIVIA-S

I take it back. Olivia won’t fit and the holder for the V22 is the same size as a Vero29 so there is no advantage there.
.

Looks like the best option is to turn down the Lenina to fit. The bad news is that the whole thing will probably easily overheat, it probably needs a copper tapered plug for the COB and assembly will be a royal pain.
.

Then again, if it was easy, it wouldn’t be any fun.

I just got a batch of CAD models from LEDiL and the Vero29//Lenina adapter won’t fit in the L6. The only option I’m seeing would be to modify the mount and then glue or tape it directly to the Vero29. However, it would also block the screws I was planning to use to mount everything into the light. I suppose I could drill hex driver access holes in the plate and then the screws would be captured….

Can’t machine the head to fit?

I think I can make it work if I can remove the plastic bits of the Vero29 from the actual COB assembly… or just use a CXB3590 and machine my own adapter for the Lenina.

I don’t think I actually need the mounting lugs… just a tight press fit boss similar to what the LEDiL adapter plates actually have in the Lena series.

I cant work out to post photos but i used the L6 reflector with cmt 2850 and taskled HBflex in a scratch build. But it fried the driver, i think the shelf was too thin and ambient heat got it. Happened twice and now im waiting for more drivers. I will redo it with copper inserts for the led and driver i will also put them back to back with a gap in between so the copper protects the driver from the led.

Would like to see it. Easiest way is to upload your photos to imgur and copy the url to the box when you click on the add photo box above the comments box.

As I said earlier, my evil plan involves a tapered copper “shelf” for the COB and the HyperBoost will be mounted to the back of the shelf with thermal tape.

Bezel got used for something else. The switch is an automotive push button with led.


Pretty cool!

Some “fog lights” im working on, not sure how to do the heat sinks, the drivers will be mounted outside the lights.

It is a big light with 5 x 26650. I dont do drawings trial and error works out more costly but good fun.

Well, I can confirm that with some minor modifications, a LEDiL C13867 will fit over a CXB3590. So, I think I’m probably going to design a custom spacer for the L6 and put the CXB3590 in there and then get a Vero29 for the Battle Lantern. Both will get Lenina-S reflectors.

So, I took the test rig out with the reflector double stick taped to the heatsink (lol) and the front lens light pipes like CRAZY. It is actually almost painfully bright.
