DIY Dive/Video Light

[Packhorse]

Looks good. What is the wattage of the LED? what deg spread is it?
I really like the idea of LEDs but they seem a bit to spead out in coverage for my liking. I am currently using a 35watt 10deg spot lamp with a 5ah 14.4 nicad battery. Had it down to 48meters with out incident but then also had it down to 43m and the plastic lens went concave and smashed the bulb. Didnt leak though. Need a thicker lens.

I am glad to read these reports.
I'm in the market for some very bright, blue light, HID.. I say
somewhere around the 200+ wattage output. I would need somewhere
around 8 of these lasting about 2 hours...
Possible to make for less than $500 each?

Thanks,

8, 200+ watt HID lights? What are you planning on doing with those???

Seriously though I don't know the exact price but I would say that if my 10 watt HID cost nearly $100 for just the bulb and ballast that there's no way you can get a 200 watter for less then $500.

Good luck though in your quest to remake the sun.

I`m using the latest generation of white LED's, its 140 lumens which is about 10W, angle of the beam is adjustable depending on the lens mounted infront of it. I have 3, 6 & 12 degree lenses.

I know carrying the equivalent of the SUN (lol) in caverns and caves may be
overkill but I would rather have than have not while there. As for the $$ ($500),
i just threw that out there.. It will cost more, but the best price is alway... The
best..

Cheers,

When you get around to building this thing give me a shout, and then checkout my DIY Site for more information on how me and others have built our lights.

Buying a cheep pair of Rocket Fins on Ebay the first thing I did was bust a strap... Surf'in the web I found some articles on DIY Spring Straps. Havent made them yet but if I can get some stainless spring I'll try em.
The LDS has nice ones so I plucked the buck. They are nicely manufactured and not that expensive for the hastle...

This should probablly be in a different thread, but I am always breaking fin straps. New ones don't seem to even last a year either. I was also thinking about making some spring straps out of stainless steel spring and some silicone tube. The problem is finding and the cost of the stainless steel springs.

Anyway I was surfing ebay and found some spring straps for about $22 buy it now price plus reasonable shipping. I would think they are stainless steel, but a quick email could take care of that. They look just like the nice ones in the dive shop too, but are less than 1/2 the price.

Have you used the spring straps? I wonder how tight the get and how comfortable they are. I like the rubber straps because they get tight, but they don't last long enough.

You can get the springs at McMaster Carr.

Also checkout this site Spring straps. I made a set of the Delrin straps. I've been using them for well over 2 years and they work perfect.
