Zoomie/TIR for nighttime photography?


Recently a new fellow at ForoLinternas came asking about a tool for nighttime photography. He needs a light with overall nice light output distribution, you know, TIR or zoom torches. I also spoke with him about CRI, standard illuminants and stuff like that, and he agrees a high-CRI emitter is a must. Also, it would be quite nice if all of the available driver modes were PWM free, I believe.

I've narrowed down the search to some sort of 26650 host, preferably. With a high-CRI 219C R9050, XM-L2 CRI90+ or triple 219C (no matter if it is a zoomie, its the flood what matters), what would be your recommendations?

One of the reason I've gone the 26650 way is the guy likes the Warsun X50/X65, and the fact that, with this format, a completely PWM-free LD-29 driver could be used.

The human mind, and its programming, is at the forefront of a particular battle of The Light vs evil dark forces. Nearly every human being on this beautiful planet “Earth” has some sort of negative mind programming in its mind. And you better take care of your mind programming, or someone else will in this wicked world.

These are very nice:
No tint shift, but a bit cooler than 4000K i.m.o.
Maybe contact seller for 100 pieces reel cutting (tape).

These are more practical, but you’ll need a boost driver:

Both options are not easy to put in a flashlight though…
But your photography question made me think of these Osrams. Smile

As Jeromemel touched on with the COB suggestion – does he specifically need a FLASHLIGHT?

Because if his need is just a high-CRI LIGHT SOURCE, his options are more open, and something other than a flashlight may suit his need better. For photography you often want a physically large light source to create diffuse lighting (hence umbrellas in photo studios). Light emitting from the small head of a flashlight (no matter how floody) is essentialy a point source and will cause harsh undesireable shadows. If he is open to ideas such as using high-CRI COBs or SMD strips for a light pannel, etc that will give him more options.

Is this for portrait/studio (short exposure) or light painting (long exposure) photography? I find that using beam diffusers (such as the Convoy diffuser – review link in my signature) or just waving a floody light around during a long exposure will result in even light distribution. PWM is not an issue unless you are using video, or exposures are short.

Below is 3x Convoy S2+ with 1A, 4C, and 7A tints (at 10% power) with diffusers.

Below was created by waving a LED Lenser P7.2 (I think) around in a circular motion during a long exposure.

I used a modded Supfire M6 with three MT-G2 LEDs for the first two photos in this OP: http://budgetlightforum.com/node/40927

3 Nichia run at 1.8A with a 26650 host will be a lot light.
Depending on how he want to light a mule or TIR will be good

Professionsl or hobby camera lights are build COB or a panel with an array
