Good luck with that, UV on those things is 395nm, at best it might add like half a percent of flavor and smell. Gimmicky and massively oversold. Similar to the misleading "organic" wording often used.
UVR8 is the receptor responsible for UVB trichome response with 95% of that happeing at peak 280-290nm. 290-300nm is 10x less effective than 280-290nm.
UVA' shares its photoreceptor with blue and is called cryptochrome, uva causes alot of ROS and using too much can be detrimental similar to having too high levels of blue.
UVB can be very dangerous when used or handled improperly, with the very real potential of messing up your DNA. Its simply not recommended for anyone who treats their grow with anything but utmost respect and can maintain high levels of discipline not to screw yourself.
Plants have mechanism that can be utilized to repair nearly all the damage done to them. Humans do not. This doesn't mean UV is evil or bad, in correct doses it can be highly beneficial. Sadly there will be little to no affect from your current UV.
