To be thorough, the amount of UV produced relative to sunlight is (usually) quite small. Negligible might be a better term.
Also, keeping in mind, some fixtures do include LEDs specifically targeting the UV band (usually UVA, sometimes UVB) which can approach similar levels of exposure as to sunlight.
Looking closer:
Sunlight
287-320nm UVB : 0.06%
320-399nm UVA : 3.06%
Integral radiant (350-840nm): 483.8 W/m^2
Shaded Sunlight
287-320nm UVB : 0.20%
320-399nm UVA : 7.39%
Integral radiant (350-840nm): 60 W/m^2
LED Heliospectra 601C
287-320nm UVB : 0.01%
320-399nm UVA : 0.12%
Integral radiant (350-840nm): 177.6 W/m^2
Fluence RAY44 UVSpec
287-320nm UVB : 0.02%
320-399nm UVA : 19.07%
Integral radiant (350-840nm): 34.1 W/m^2
So from these, we can make a general estimate as to the power in the UV band for the listed lamps (note: this is not the correct way to calculate this but it works as an estimation):
Sunlight: ~15W/m^2
Shaded sunlight: ~4.5W/m^2
LED 601C: ~0.23W/m^2
LED Fluence UV: ~6.5W/m^2
For the single LEDs fixtures shown, relative to sunlight, the amounts of UV are small except for the LED fixture that include LEDs that specifically targets UV. As the number / power of the fixtures increase, there would be a corresponding increase in the UV band power.
