You can buy full spectrum LED lights (99 CRI, or grow lamps)

The article uses LED as synonym for typical LED lightning.

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.

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?
