I’m more familiar with the advancements in CRI in recent years than dUV (this is the first I’be heard of that) but LEDs can now be purchased with equivalent CRI.
The context of this discussion is incandescent color/perception/experience.
My point is that CRI alone isn't sufficient. Nor is CCT (correlated color temperature). In practice, two bulbs with the same CRI and color temperature can have drastically different tints.
It all boils down to how these measurements work. In practice, the vast vast majority of LED bulbs do not even remotely come close to the color reproduction of halogen. Not to mention the flicker response to 60hz wall power.
There are a handful of companies that produce extremely color accurate LEDs but they're expensive and have limited lifespan.
I can’t recommend Waveform Lighting’s 95 CRI products highly enough!
The wonderful warmth of incandescent (depending on your color temp prefs) with no wasted IR energy in the form of heat. What’s funny is that your mind will perceive it as hot because we’ve been conditioned to expect it from light at that color temp.
Reasonable price, too, but more expensive than bulbs from the big box store. For something that lasts 10-18 years, it’s worth it to me.
Well OK, I was more speaking in the context of a reading lamp. And I wanted more to point out that an LED lamp with smooth color and brightness spectrums allows for you to find a better sweet spot for comfortably reading at night.
