I like this photo , it shows the amount of light that 100W one can give - after all they use this kind of lights for lighting gardens and buildings
Yes, sorry, this thread is about your custom lights, and I forgot to say they are excellent, would like to see a video of the beam during actual diving, if you ever record one
Believe me after the tests with my 50W last summer I am very curious to see the 100W one this summer
I already have my DYI underwater case (cost ! euro ) for my 808#16 spy camera
You can check my other 6 youtube videos I believe you will find a lot of interest ideas and patents there and one underwater video (day time)
Nice! You could unsolder the FET's on the board, run some heavy gauge wire to the aluminum body and thermal glue them to the side (just make sure they stay electrically insulated and the wires too)
Can't wait for the underwater video's! :D
You might get better space and aH per volume if you used some of those LiPo square cells vs the big honkering round ones, still...wow...just wow!
Out of stock, but 36V NiMH battery pack (if it would fit)
I must say to you the same that I said to another friend 2 comments before (why I choose one 100W led)
Its all about cost - these KING KONG batteries cost me 8$ each from CNQualityGoods (free shipping)
I also have one more 50W flashlight (my first attempt) with a 3 cell lipo 4000mah Turnigy battery , the battery cost about 35$ with shipping
The reason that I didn’t like lipo batteries for this project is that they need 2 different kind of wires for charging (balance) also is much easier to fit 3 or more cylinder batteries connected with wires into the main body than one pack battery
I am aware that cost is very important to you but changing those generic chinese “100W” led arrays with something more decent (Bridgelux, Cree, Lustrous…) would give you much more improvement regarding lumen output.
Yes I believe they do , but already I decide that 50W is more than enough for almost any kind of underwater light (diving or just fun -like me)
The 100W one I just make it for fun and impress my friends , if you don’t want something very strong for specific reason the 50W one with this amount of light is perfect
If I had to choose something better I believe that cree-t6 (100W emitter) even working with 50W driver will be better
I already made a 50W flashlight for a friend of mine (photographer) that dives to 30 meters and he is very happy with it , until now he had to pay about 100 to 200$ for a decent diving flashlight around 1500 lumen
I remember doing a comparison of a 100W panel (running at 100W on a bench PSU) to a 3x XML light (with the XMLs running at 3A) and feeling like they were roughly on par in terms of output.
The math on that doesn’t quite make sense now that I think of it (100W vs ~30W), but that’s what I remember.
For underwater videos I will use my 808#16 (720p) camera with waterproof case that I made with 1.5 euro
I believe that now is the smallest and lighter action camera out there
In my youtube account you can see all my 6 DIY video , you might find them interesting
