Anybody making 30 to 60 thousand lumen dive lights? Besides Big Blue??

[Calabash Digger]

I was wondering if you guys knew of anyone else making high powered dive lights ? 30 to 60 thousand lumens is the range I am looking at.... With a good burn time 90 minutes or longer...

For what? High end clear water video work? Divide BigBlue published lumens in half. What light are you using now?

Other video lights manufacturers include Light and Motion, Kraken, Keldan, and Gates. Anything close to true 30K lumens isn’t going to get the burn time you’re wanting outside of offboard battery packs and scooter sized rigs (or lying about both lumens and burn time).

In recreational and technical diving purposes, I’d be hard pressed to need that much light. If you’re diving in the poor vis black water you’ve mentioned in previous posts, get an LM HID or a Halcyon Focus/Flare for a lightsaber style quality of light.

Given the location and jug in his hands...I’m guessing black water diving. OP...have you considered three inexpensive 1,000 lumen lights and mount them to a helmet? Have one 1,000 lumen light hand mounted (ex. glove) to sweep).

Do you mean 30 such lights? He is lookin for 30,000 lumens, not 3,000.

Spot or Flood?

No, I mean that diving in those conditions, you don’t need 30,000 lumens. Black water diving with four 1,000 lumen lights makes it seem like it’s a day dive.

That’s why I prefaced my post with “have you considered...?”

The best LED chips convert electrical energy to luminous flux with an efficiency slightly better tha 100 lumen/watt.
Hence a 30.000 lumen light source requires 300W of electrical power.
And if the battery pack must last one hour, it will be a 300 Wh battery pack.
It is an huge battery pack.
It will also be a dangerous battery pack, which is forbidden to carry on an aircraft (the limit is 100 Wh).
So read the electrical specs of the battery pack: I doubt you find any manufacturer selling such an huge system.
This means that they lie on the real luminous flux, or the real duration (but this is more rare, as the customer will immediately detect the fraud).
Energy cannot be created from nothing, so learn to rely on energetic quantities for having a more realistic evaluation of the lumens produced.

Black Water...I am running two 10,000 big blue 120 degree lights tethered together at the moment with a burn time of 2hrs. Yes I do mean a 30,000 to 60,000 lumen light. Big blue has them with 90 minute run times already....I was just wondering if anyone else makes such a light..... As far as Barnabys Dad said about the 4000 lumens making it seem like a day dive...that was not my experience with 4800 lumens of light I used to use...needed more. Here is my light set up in action...that is 20,000 lumens 120 degree...

Yeah so that’s less than 10,000lumens total and even fewer a few minutes after they’ve been turned on. I’m not sure how the Keldan actually tests but at least their math in wH makes slightly more sense. Light and Motion is pretty accurate but at loss of burn time.

Have you tried tight beam lights? You get a lot more light on your subject per lumen compared to the video lights you are currently using.
