Question DIY Light Resources?

[EmotionalSupportLight]

Hello DYIers,

Im currently in the housing design phase of two 11900 lumen high CRI video lights with a controller and battery canister for my gopro setup.

I have a rough idea of how i want them To turn out, but i was wondering if there are any resources out there for divelight design.

Ive read about the Dive Light Companion, but there are no copies available to me

I have no input here, mostly to learn as well, but mainly to say your username is quite awesome

Not really, most everything you can buy as a hobbiest is geared to the flashlight markets and small size/single cell.

Housings are the hardest part to get right/modify.

The price of half decent lights these days is in reach of mere mortals so not a lot of activity in this endeavor in recent years. I think video lights are a big exception (ie still $$$$) so I'd love to see what you come up with! Here is an older resource that may be helpful. I've often wondered for a video light head if you could build something in a flat panel style, oil filled and with direct cooling to the back of the MCPCB.

Thank you! I like the idea of a PVC cannister, i was going to go with annodized aluminum but maybe ill reconsider.

As currently planned, my 130W LEDs will be essentially just mounted inside a finned annodized aluminum heat sink with 1 hole for a cable gland, one 1/4" tap for a ball mount and an acrylic dome. I have access to a lathe so ill do the milling myself. They should be quite low profile since the LED driver, switches and other electronics will be housed in a seperate panel that i will attach to the camera tray below the gopro.

A few advantages of this setup i can see are: not having to duplicate a bunch of electronics for each light, since i want 120° flood angle, and the LEDs emmit at 120°, i dont need to add reflectors in the lights, further shrinking the light size.

As i start putting this together, ill take pictures and make a post outlining my project. A good chunk of my electronics arrive today, so I look forward to getting this together and testing my ideas!

PVC is more brittle but I think if using pressure pipe like schedule 40 its no worry and much faster to fabricate than Aluminium which you need to have anodised. I really like the sound of your light heads. Similar thinking to my idea but avoiding any oil fill by using a dome (is the dome off the shelf or you will make custom?) I recon you will be able to overdrive those LED's pretty hard if they are direct attached to a finned heatsink that is in the water.

Looking forward to progress reports

Off the shelf dome hopefully, blue robotics make a nice dome thats reasonably priced that is ment for aquatic ROVs. (Cylindrical Locking Series (2–8”) Archives)

I will probably use aluminum and anodize it myself for the sake of experiment
