Ring of light

Those pictures are fascinating packhorse. The ring sure sends a nice even flood out there. Is there in particular reason why you used K2's for your project instead of something else?

Yes. As explained in the above posts I had plenty spare from modifications I have made to other lights in the past.

Will that ringlight fit an Aquapac #420?

 

[Packhorse]

Wouldnt have a clue.
ID is about 110mm OD is about 190mm

It was designed for a Canon G10.

It wouldnt be all that hard to modify it to suit any housing who's lens port is less than 110mm wide.

Hello,

I am interrested to buy a set of the light if possible, i could attach all parts myself though... making the rings is not possible without good cnc machine i think. Please let me know if this is possible.

Greets,
Dan

I dont have kits available but I am willing to sell this one as I want to build some thing a little different.
I will sell it as a complete system or just the light ring and you will need to source your own battery cannister.
PM or email me for details

A couple of recent pics..

In this shot I used just the bottom LED's for effect.

Dude! Those pictures are great :thumbsup:

 

[Packhorse]

Thanks. I really like the attitude that the lighting gives the scorpion fish. Reminds me of sitting around the camp fire telling ghost stories.

Amazing! Great composition and exposure :twothumbs

Very nicely done on the ring light and beautiful pics. How did you secure the ring light to your housing?

 

[Packhorse]

There is a L section of aluminium bolted to the back of the ring. The housing is bolted to this also via the tri pod mount.

 

[Nated1971]

Brilliant....pun intended. Thanks.

There were a few of aspects of the MK1 that I wasnt totally satisfied with.
Two of them being colour and brightness.

Easy fix to both. Swap out the 24 direct driven K2 LEDs of unknown bin to 16 XP-G R4's that have a much more neutral colour.
LEDs are wired in 4 lots of 2P2S set up with 6 1 Ohm resistors wired giving 0.66ohm.

I can still run the top half or the bottom half or all at once.
Current consumption is 3 amp when half the LED's are driven or 4.7amp with all driven indicating there is quite a voltage sag in the 8.4v 10Ah battery pack. So the LEDs are not driven at full potential but I am happy with that.

Hopefully post some in water pics in a few weeks .

A short video inside a cavern using my G10. Back scatter is pretty bad but video was not the intended use of this light.
The 2 other lights seen in the video are both quad aspheric mag's.

Is there any interest in making a commercial product?
We are a Canadian group in Shenzhen, China with access to Seoul, Cree, etc LEDs, battery manufact., and machine shops.

 

[Packhorse]

I have had no real interest.
But if a commercially made light was produced I think it would have some market.

Impressive shots:thumbsup:

That's one nice light. The pictures have incredible depth and and a character that you just don't see in u/w photos. Much better than a single or dual strobe config!
