In the UK I've not been able to find high wattage (10-20W) LED lightbulbs with high CRI, some don't even mention it in listings, let alone SSI, which I have never seen.

Where are you seeing these? Is this industrial/commercial suppliers?

It’s rare, unfortunately, and usually not in the typical bulb formats. Here’s one for example with an SSI of 89 for tungsten: https://amarancreators.com/products/amaran-100x-s?Title=Defa...

Phillips, try searching for EyeComfort. I think all of their premium bulbs have 80+ Ra.

GE Relax is my preference, with 93 Ra. A good all-around bulb.

They look good, but cannot find a listings with all the details though to know exactly what I will get if I buy them.

It is a good start and I know know its wroth looking, so think you.
