You can buy full spectrum LED lights (99 CRI, or grow lamps)
The article uses LED as synonym for typical LED lightning.

How is "full spectrum" defined in this case? Visible spectrum is not the subject of the paper, as they care about infrared.
Also even limited to visible spectrum, I have not seen any 99 CRI bulbs. The highest one I have ever found are the 98 CRI by YujiLED, but you pay around $35 for a single bulb. It is absolutely not "easy" to get flicker-free high CRI bulbs, let alone ones that cover the infrared range.
https://www.waveformlighting.com/ sell 99 CRI LEDs. They're in strip form not bulb form, and they're definitely expensive, but they are available.
Specialized stores or online. If enough people start buying them, they become popular and cheaper.
Phillips, GE, Cree, and others sell high-CRI bulbs.
10 years ago you had to work to find high CRI bulbs but could still find Cree bulbs pretty easily. Now you can get high CRI bulbs at the grocery store.
High CRI bulbs generally have low or no flicker because high CRI is toward the premium end of the market.
IR emission is not a "feature", it's a bug.
