Dive Light

[RX8Bob]

Will do tomorrow night as it is currently raining right now and dont feel like standing in the rain to take pictures. (Yes i know its a dive light, but i hate the rain.)

And 15 degrees may sound too wide, my first impression it was too narrow. But when i put the 15 degree lens in it was good for me at least. 15 degree is the narrowist lens available that is made for that LED at the moment. Seems they've released more variants and color options of that LED since i started using it, so perhaps others may become more available.

I was not suggesting anyone currently purchase one of his lights as I am very aware of that post. In Bob's, original post he mentioned his prices would be around what the Manufactures sell there lights for. I was using his thread as a point of suggestion for Price comparision's to sell his light.

a22shady, i was simply just going off the lowest prices i could find for the Dive Rite lights. Which I suppose wasn't an accurate thing to go for.

N/p Didn't mean to offend I just wanted to give some info for comparision as If you priced it at same price as the Big Man(Halcyon-Light Monkey-Diverite) You would have gotten a bunch of people to tell over priced and or would have had a difficult time getting order's. Just wanted to show you what others current offer. Best of luck with your light sounds great and Bright Curious as to how well it will trully work here in our area as we tend to have less then Ideal conditions and problems I hear about the LED is they can't focus well enough to allow them to punch through the water and the particulates tend to block the light

I finished making the light about a week ago, and was planning on using it in a dive as soon as I could. So to answer the question about it being on a dive, as of yet, not yet. Will it be? Yes, as soon as I get my tanks back from hydro. On a college students income, its a bit slow going getting out on a dive.

I make no claim as to throwing light further than a 21 W hid, I am mearly comparing to an LED light as HID are vastly different. The only claim i do make however is that my light has 2+ times the output of a 21w LED light as the LED i am using is a 40w LED.

The lens i am using is a 15 degree lens which changes the focus of the LED from 110 degrees to 15. The Lens being made specifically for the LED does a great job of focusing most of the light into 15 degrees. There is still that halo around the center as with any light.

What i'll do, tomorrow night, around 10 PM EST after my Math Exam i'll take pictures of the light output/pattern.

Just to be accurate...your light just happens to be twice as bright as a 21 W HID but it's not because yours is 40 W. You're comparing apples to oranges. For instance a 40 W halogen would probably be 500 lumens.

Yours is 2200 lumen because that's the spec of a SST-90 driven at 9 A.

Yours is 2200 lumen because that's the spec of a SST-90 driven at 9 A.

No, because the LED i'm using is not an SST-90. And infact only requires 1 amp of current. Anymore would destroy this LED. The LED I am using requires 43 volts (Contained in the light head and only the light head as the battery output will be limited to roughly 14 volts and 3 amps), and 1 amp to run full bright at, 2400 lumen.

I also made a typo in that one post, i meant to say i am NOT comparing an LED to an HID. But rather comparing my light to other's 21W LED lights.

Looks like it will make a nice video light. 15 degrees is too wide of an angle for using it for signaling.

unfortunately, the images arn't the greatest as my camera is missing, and so i was forced to use my cell phone. Please disregard the quality of the pictures. The first few pictures are of the light head, yes it is missing two screws as i didn't fully assemble this one due to the pc board getting painted tomorrow. I chose only to post links as the images are fairly large.

The actual design is slightly different as this was the prototype. The new design improves on this slightly.

The light has been redesigned and should be available within the next few weeks. No longer using a set of two buttons but a single switch controls the entire light. The light has been pool tested to this point, and will be tested in realistic dives in the upcoming weeks. Pressure tested to 225' at this point, the change in parts should increase the rating of the light to around 300 - 400 PSI. Easily pushing the light to a max depth over 300' I'll have more info and updated pictures soon.
