White LEDs have improved dramatically since the original Home Depot-spec Cree series (including TW) was released. It might be you're not seeing the CRI advertised because the entire stock has improved quite a bit compared to 5+ years ago.

Are there any equitable bulbs on the market that have such a high CRI (specifically the R9 metric)?

Some are already dimmer than I would like but thankfully LED's don't "die" like filament bulbs so they're still serviceable, providing the light of a 40W halogen rather than the 100W they originally started with.

I always go for bulbs with >90 CRI and warm/2700K temp and these fit the bill. Since they just specify >90, I cannot know whether it is actually 91 or 95, but the light they produce is generally quite pleasant to my eyes and not much different from some expensive CRI 97 ones that I bought elsewhere.

ludi wrote:Wasn't the TW series based on the first-gen bulb design with the heatsink base? It worked great for a first-gen device that had to deal with excess heat, but the entire thing was an unfixable defect. I stripped a couple of those down to the bare bones, it had way too many parts configured in an expensive-to-manufacture arrangement.
