Someone please tell the Australian government now that we've essentially banned other forms of lighting. (except fluorescent)

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.

Call me when there's lights with a cri r9 of 99
You can't buy heat lamps? They are even more infrared and last longer.
Also LED lighting can have infrared, have a significantly more smoother spectrum curve and still last +20k hours without burnout. The cheaper bulb spectra that they show is a blue led + phosphor coating, but there are infrared LEDs, UV leds, and more. You can make quite the convincing sun simulation, even better than any incandescent bulb, but there is almost no demand for UV + Infrared super full spectrum lighting unfortunately. Only movie & theater lights come close.

Do you have a link to a bulb that you can purchase meeting all these criteria? The only one I'm aware of was this obscure "StarLike" that was never actually sold in bulk. LEDs can be made good in theory sure, but in practice they are all terrible in light quality compared to a standard incandescent.

You would need to see the spectra of the various LEDs available and create a mix along with phosphor mixes. The closest thing is something like a BLAIR-CG light engine from aputure where they have something like 9 different colors of LEDs that mix together, but they don't put any infrared leds in them because they are for movies and they don't put any UVB or proper UVA leds. But there are infrared, UVA & UVB LEDs that you could apply the same kind of engineering principle to make something that closely follows the sun spectra.
No, you can't buy them as bulbs. The closest thing is those red light therapy panels that include them.

Typical electricity rates in Australia are up to 40c/kWh or so.
Do you really think $5 AUD per month per bulb that you’re running 8 hours a day is worth it for better spectrum quality?
Are we also going to ban powerful computers since they use lots of power?
High-powered computers are a niche issue, which means on a society level there's little benefit to restricting them.
Lightbulbs on the other hand affect all of society, so they've got a much larger impact to the overall CO2 budget.
Additionally, the average person uses a laptop or mobile devices, all of which use less power than even a single typical incandescent bulb (and people usually have many lightbulbs).
Replacing incandescent bulbs with LEDs saves a lot of CO2 at basically zero cost, while getting rid of computers saves less CO2 for a much larger economic impact.
And even the effect described by this article has to be looked at in context, considering most of the light people experience in a day — and have experienced for the since homo sapiens existed — is natural sunlight, even in northern Europe during the winter (that's why EU law mandates windows with sunlight in every office, apartment, bedroom, etc.)
Sad to say, but concerning the PC, seems we're moving in that direction pretty fast.
I hope they don’t come for my 386 with 14” CRT
There are efficiency standards and laws for large appliances.
This isn’t some kind of controversial subject. Ensuring home appliances don’t overconsume energy is beneficial for everyone in society.
You don’t want to have brownouts, blackouts, or run out of heating gas/oil in the winter.
You bring up the idea of regulating computer equipment power efficiency as if it’s crazy talk but it’s a real thing in concept. Governments do offer guidance and sometimes regulate computer efficiency. They have efficiency standards (e.g. Energy Star) as well as relying on industry standards (e.g. “80 Plus”).
Take a look at your computer monitor or TV box and it probably has an energy star logo somewhere if you live in the US.
The US federal government and other state and local agencies will not buy computer products that aren’t energy star compliant, and encourages businesses and individual to follow similar standards. Other countries might regulate further than these (dis)incentives.

And if you bring up data centers, those are considered productive industry that has its own regulations different than home regulations. Plenty of things legal in industrial series aren’t legal in your house.
