Yeah, far UVC is great for the exact reason that it's far less harmful to human skin. However, "far uvc" (207-222nm) leds are even more expensive. Many far uvc devices aren't available to general consumers (to control demand). The units that are available to the general population are incredibly expensive, at least $2k for a lamp large enough for use in a small bedroom.
