You mean around the switch and cable exit?
Yes around cable exit, switch and the LCD panel
I would aslso seal the inside of the battery voltage indicator with acryl or silicone so the whole case stays watertight
or add a transparent cover on top of the display
for the cable there are cheap strain reliefs like this you can find in any home depot or ebay
Yeah, some good ideas I might do that.
The cable is 17mm thick, I don’t think it needs any strain relief xD maybe I can find something that fits it though.
There’s only 17mm of space between the batteries and the case wall though.
the strain relief takes only like 5-8mm inside the case
there are multiple sizes from a few mm to over 50mm
Nice project mr!! :+1: 
Thank you 
It’s a popcan light on steroids!
Have you measured the inside of the reflector, I was thinking about focalpoint difference by using LED compared to that HID bulb?
I have no HID/LED conversion knowledge…but just curious… 
Awsome looking project, and I really likt to follow your tread and see the final result! 
The reflector is about 96mm diameter, and the HID bulbs have ~4mm arc so switching to the XHP70 which is about 4mm diameter should give similar throw.
But since the bulb looks unfocused I will probably get way more throw with a well focused LED.
Well, personally i just hate devices with attached cables.
Connector can get stuck somewhere and pull the device out your hands, cables go weak near the device by bending, it may not fit in a case because the protruding cable…
I didn’t know powercon was so expensive though.
I have some speakon (also Neutrik and not much different, and speakers draw more current that their amplifiers) stuff which was not that expensive.
It’s an awesome light, Enderman.
I first thought: What an ugly and bulky handle contraption, but together it looks awesome.
A thought about the batteries:
Maybe best to put the balance charging connectors in parallel too.
So that the cells are always averaged out with eachother, and since the outputs are in parallel already, you’re gonnan have to do that for balance charging.
How do you charge them anyway?
Something like this you can build in the batt. case:
You may need additional current limited regulator, have no experience with this.
Thanks the way I mounted the cable inside shouldn’t cause any damage, I can hang the whole case by the cable no problem.
I’m also not worried about it going weak because of how freakin thick the cable is, it’s basically it’s own strain relief xD
The reason this needs an external battery pack is because I want to be able to run it for many hours on a single charge at max brightness, and the light is already heavy enough as is.
With the battery case I can stick it in a backpack so the only weight I carry is the light. The battery case weighs like 3 or 4kg or something, don’t want to be holding that for hours…
PS- it looks sick when you have a huge cable coming out of your back and into a bomb-looking flashlight in your hand
I charge them individually with a hobby charger.
If I was charging them all at the same time then yeah I would need to put the balance plugs in parallel, but I heard somewhere it’s not recommended to do more than 2 parallel batteries per balance plug. A better solution would be to have an auto balancer PCB for each battery, but that would overcomplicate things a lot.
Since the batteries are meant to be easily taken out and used for other projects I prefer the simple one main plug per battery.
Dont like it at all, i absolutely love it!! This floats my boat big time……………….great ideas with the batteries and case, awesome………….go big or go home!
I know your not going to do it(iirc your more a throw guy anyway) but i just cant help think about 40 or 50x xhp70’s in there………….and over 100k lumens. Back to throw(unless missed it), are you going to go shaved dome xhp70 to get more kcd out of the beast.
Great choice of host great work ……………did i say i love it
Usually in battery packs groups of paralleled cells are put in series though, and it’s easier for charging too.
You could make a decent 4 pole connector in the peli case.
The XHPs get very inefficient at high currents, I only use the XHP70 at 12A because I want good throw too.
In the future I might make a similar can-light that is only focused on lumens, and it would use a single COB LED (because that will give much higher efficiency).
Something I try to do with all my lights is give them several hours runtime, something that makes 100k lumens for 20 seconds is no fun. That means I need to design more compact and portable battery systems.
Anyway, that’s a project in the design process, so maybe if I get some sponsored money I can build it in a few years.
Yeah, not in RC, we only parallel series batteries because all the cells are identical and always discharged the same, so as long as you balance charge them it doesn’t matter 
Any more progress?
Oops, missed this post
Currently I’m finishing up another project so I don’t have the $200 I need for the new reflector and heatpipes to convert it to LED.
Probably in the summer I will do the conversion.
Right now it works, and I want to take it out some night for beamshots.
Oh, what kind of reflector do you plan to use? Is it made of gold?
Seriously, what diameter has the reflector? There is a SMO and a OP at Kaidomain with 86 mm for under 20 $.
Probably a quality precision eletroformed reflector. It’s worth it just for the looks alone :D.
Just one warning with that light.
