You're still making apples and oranges comparisons Dave. There's a huge difference between the current requirements of a continuous light source and a flash unit. There's also a huge difference in the light output of both -you're not gonna freeze motion with that flashlight you built...

Not gonna continue this discussion either cause it's pointless.

Sigh

There are already photos posted on POTN that have been illuminated with that light: Tawny frogmouths, possums and owls at night.

I have provided details on current capabilities, links to graphs by a test site.

I could not care less about you. Other people read the forums, it is for their benefit I post.

For people other than Dalantech:

ISO 800, f5.6, 1/125 sec.
So ISO 1600, f4, 1/500 sec would be the same exposure.

For anyone that is interested I will update this thread with some pics taken with my current photography torch.
Ironically the torch I have shown already is very floody, so it would be excellent for macro, but due to spreading the light so much it's not ideal for nightime wildlife.
This one has a very focused beam, runs on 2 IMR 18500 cells, but would run fine on 2 x IMR 16340s, the cells I have been talking about.

Dave,
Wasn't gonna post to this thread again, but the PM function seems to be broken so here's my last attempt...

You do realize that you posted several images that are not even closeups in a discussion about lighting in macro photography?! I don't think you understand how much light is required to expose a scene when shooting at 1x and higher magnification. Yet another example of an apples and oranges comparison...

I much preferred your previous post about not continuing the discussion.

Again, for people other than Dalantech, just demonstrating my previous claim that this light is excellent for macro.

1/180 sec f11 ISO100

So if I wanted to use ISO400 that would be 1/720 sec at f11.
Straight from camera, just resized. I tried 1/125 sec but blown highlights.

Clever, but the advantages over more conventional macro lighting solutions seem unclear.

This 'news' is over a year and a half old, not sure why this thread even exists? We certainly don't seem to be discussing the theory of this design even?

Yes I agree we have wondered off topic.

The use of continuous light sources is of interest, might be worth making a new thread for it.

As Lester said, the thread has wandered off topic. It has turned into Dalantech disputing whatever I say.
I just mentioned that this light would be excellent for macro and you can see his response above.

I have never used the light for macro before this. The only advantage I can think of is it is one fantastic modelling light!
The fact that it has High CRI (Colour Rendition Index) LEDs does make it relevant to photography and in this case used as a primary source of light for a macro photo.

I intend to start a new thread regarding the use of my currently used torch for nigh time wildlife which I have found surprisingly effective as a primary light source (I think I found out when I took a 2nd shot before the flash recycled).
