The best way to avoid some issues, is to buy a HID car xenon kit 55W 5000K
and build one light box, forgetting the heating problem!

At some point though, one must consider the thermal issue.
I was thinking of reversing it, pointed into a reflector for a light table or a ring light.

The Leds do not lights directly to the subject... they are fully housed in the acrylic ring, which diffuses the light to the subject.
With the dimmers you can control up-down and left-right luminance.
For the thermal issue, in front of each led the ring has a hole through , for air flow!

Great idea. Love the implementation. Can you supply the drawing of the ring, pdf, iges, step or ? and the p/n for the led's. They appear to be around 5000K.
Sorry, no drawings for the ring!
Some small things that I idealize, i don't need drawing to build them!
The ring dimensions will have to be fitted to your lens.
If you want to build one, weekend i can do a drawing to help.
You have to sandblast the leds to have better difused light!

Zundapp5, have you published the building instructions anywhere?

Unfortunately no, but if you want to build one, I can help!
The ring and the housing holes for LEDs, must be accurately machined!
This is not within reach of everyone who wants to do it at home without the proper tools.

There are a millon ways to make "white" light--
only some of them will work with your camera.
It's good thing you've tested it.

Not chip chinese leds!
This leds that i've chosen has phosphor filled in the reflector to converts the
blue emission of InGaN chip to ideal white.
By the way, I've chosen a good switched power supply and specific dimmers!

LED ring lighting is clever, but I hope you tried those LEDs
first for color.

They are white LEDs, High Brightness and been tested before!

The addition of the rotating microscope objectives... that does the job well, except we need some magnetic coils to bend the light. Black hole lens effect.

The lighting, is on the way!

I'm impressed. The only component not in there is an oil immersion objective!

Love it when ingenuity bypasses spending $$$ on equipment! Anxiously awaiting your results. Nicely labeled setup, BTW.
This ingenuity, is not the only one!

Hi everyone,
Working distance; 5 centimeters.
Soon, iĺ tell the magnification and upload a test shot

I doubt the intense cold of Florida winters would bother that rubber ring. 
The rubber deteriorates with the sweat of the hands, or fat from beauty creams for hands!
By using plastic rings, this does not happen

While impatiently awaiting a D850, I'm looking at lens choices. The new Tamron 150-600mm G2 looks like a good candidate but I only see reviews mentioning the Tamron 1.4X and 2X teleconverters. Does this mean Nikon TC's are not compatible?
That depends, which Nikon TC's you have
I don't know Tamron's, but I've modified my TC-20Eii to fit on Sigma 150 600 Sport, but I d'ont like the results.
