Very interesting. I would like something like this, but not with LEDs.

Hydrargyrum medium-src iodide lamps are an alternative (artificial sun lights for movie sets), but you'll want a good AC unit in your office

		I thought hydragyrum was a made-up word, but it's the Latin word for mercury, which explains the Hg chemical symbol. (Just in case anyone finds this interesting.)

Very curious why you want to avoid LEDs

No infrared spectrum

		You can buy IR and UV leds. All high end grow lights have these for plants. Low quality cheap led products won't include them but that is nothing to do with LEDs themselves that is just consumer preference and price conformance.
