Until there’s an LED bulb which is advertised as dimmable, rated for enclosed fixtures, and flicker free, we don’t have an ideal LED bulb.

Right now as far as I know you have to trade between those features. You can have flicker free but not the other two, or the other two but not flicker free.

You could take a flicker free Waveform bulb and attempt to dim it, and also put it in an enclosed fixture, but it will lose brightness relatively quickly in an enclosed fixture.

I just use Incan/Halogen where I want dimming, which is bathrooms and bedrooms. This is better than LED dimming because the CCT also drops as the bulb is dimmed.

An alternative option to LED bulbs is to build a custom system with dimming LED drivers, like certain models from Meanwell, and use some super high CRI COBs like Bridgelux Thrive. Then you can have it all, but this is not very practical outside of a new home construction, or a garage or basement environment, or a stand alone lamp.

About the “California Building Energy Efficiency Standard CEC JA8-2016 Title 24” which the 90+ Lighting bulb is advertised as complying with:

• CRI must be ≥ 90
• R9 must be ≥ 50
• Flicker must be < 30%
• CCT lower than 4000
• Rated life ≥ 15,000 hours
• Minimum 10% dimming required

I have not noticed flicker or any effects of flicker from the 90+ bulbs.
