How about adapting something like this? 5730 SMD 8W LED Panel Circle Annular Ceiling Light Fixtures Board Sale - Banggood.com
this one is 115 mm oor 4 1/2" so it might be close
12W 5730 SMD LED Panel Circle Annular Ceiling Light Fixtures Board Sale - Banggood.com
the 18w would be overkill with its 180mm ID
18W 36 LED White/Warm White Panel Circle Annular Practical Efficient Ceiling Light Sale - Banggood.com
Price is good though

After I posted that and happened to be in the shop using my Bridgeport, I'm wondering if any of those are a great idea. My reasoning is that if the ring light is mounted up at the top of the quill, the quill/chuck/boring head/etc. would cast a shadow at the end of the drill bit/end mill just where you need the light. A light coming in at an angle like the original posted did may be a better idea. Banggood / Gearbest / Aliexpress all have the LEd / driver as found on E-bay in an earlier post.

I think the LED ring is the solution adopted by Ralph in the other post :
He doesn't seem to report any drawback about it.
It's clear that I already had the LED and driver, so I built my solution around it, the ring is also a good solution.
On the other hand, I think my lamp is better protected from hot metal chips flying away.
Electronic stuff doesn't like it very much.
But I don't know in the above product if the 8 W is the overall consumption, including the driver or really the LED power.
What is the power of the ring you used on your mill ? Where did you purchase it?
