Custom or Modified ring light for a microscope

Hey all,

I was referred here from r/flashlight. What I’m looking for someone to make or modify for me is a ring light that attaches to microscopes. I work as a jeweler and film many of my projects each week for my social media channels. Unfortunately all the ring lights that I’ve come across have really low CRI and too cool color temperatures, making the jewelry being illuminated always looking washed out.

I would love to commission someone to modify one of these ring lights to have all high CRI emitters, and ideally make something where I can switch between emitters of different color temps (5200, 4500, 3000 for example), and to have a way to adjust the brightness using buttons or a dial. This would be powered by a 110-240v adapter, not batteries.

If it can’t have color temp switching, then I would want 3 separate units.

I’m not sure if this would have to be custom built or if an existing ring light can be modified.

Any and all help would be appreciated!

You’re going to love it here, Zander!

There are fiber optic adaptors that let you pump light from an external source into the adaptor, and the adaptor dumps the light out in a ring shape. I’m not intimately familiar with how these adaptors work, but it seems plausible for you to use any light of your choice without worrying about form factor.
Example: Fiber Optic Light Ring for Microscope Illuminator Approximately 36" Long | eBay

To engineer a dedicated microscope light with high CRI and variable CCT is difficult because the latter requires a huge hardware overhaul to implement. A flashlight with this function is much easier to find, e.g., Convoy S21F. If this method works, the combined cost of adaptor + light is less than $100.

Instead of the S21F, you may consider buying copies of the S10 in different CCT. The reduced head diameter should couple much better to the fiber optic.

Found this one with adjustable color temp.
Bet the CRI sucks.
All the Best, Jeff
