(Let me know if I misunderstood; I’m reading your second sentence as “why aren’t the companies...”) On company size: The industry is split between emitter companies and consumer product companies; the emitter companies sell the far-UV emitter (basically the lightbulb) to a different company that builds the housing for consumers. The emitter companies are usually a branch of a larger electronics/lighting company; the consumer product companies are usually very small.
Some companies have run their own studies, but most of their installations are much too small to be studies in themselves. One problem I’ve heard about in the case of at least one larger installation is that the customer who sought the installation wanted the data to remain confidential. Otherwise, large studies are indeed mostly too costly for these companies to self-fund entirely, but they may offer partial funding or provide their lamps at-cost or as donations to studies.

Thanks that does help clarify the challenges for me.
