Check out Mars Hydro UR 45 Infrared and UV and it is switchable for either one or both on.
I just received them- haven’t installed yet

It's known to help. You'll get varying answers like 15min intervals, or 1-2 total hours at the mid-point of lights on. Just don't run them the whole time and BE CAUTIOUS working under UVB

With the higher output t-5s (75%?!), I would imagine everything around it would end up just like things left outside under the sun all day, but in your grow space/tent. Anything that isn't UV protected will deteriorate rapidly depending on the amount of use. It adds up quick overtime, even with minimal use. Even my lower output 15.0 reptile UVB t-5s I use over my aquarium/basking platforms wear out the plastic backround/poster material I have nearby it & need replacement every year. I don't go looking at it all the time, but its on most of the day in the laundry room for my turtle.
I feel the reptile t-5s are safer to experiment with on plants, with the lower output for longer periods, like a few hours as opposed to minutes with the ultra HO agro whatever bulbs.. I especially use my older worn out UVB bulbs from my aquarium, that still put out loads of UVs that are more suited for what plants utilize anyway. Bulbs are only good for maybe a year max before they don't put out as good, but I still get my moneys worth from each bulb!
IMO it's really not practical at all unless you go all out, and make everything exposed to the light UV resistant. I would hate for any equipment to get that sun tinged color, or my walls to start flaking away..

It's not worth risking your health. Why do you even figure you need it (you don't)? Is it because it looks cool?

I recommend Gateway Safety 28GB66 Conqueror Wraparound Eye Safety Glasses. They are used in gas welding/cutting, and meet the ANSI spec for IR Shade 5 (99.9% block of UV-A, B, and C). They also meet the milspec for impact protection (e.g., BBs shot at them etc). There are other Shade 5 specs like the well known Nemesis, but once I had those specs in the car, sun was in eyes, so I put them on. Discovered I could not see red traffic signals or any red color at all. Not an issue with the conquerors
at all, drove all over and went shopping fine. The conquerors are stylish and cheap, $13 currently on amazon... https://www.amazon.com/dp/B00FA4OVPG

here is something that a book im reading says:
"The amount of UVB light a plant receives affects THC and terpene production. Plants growing under higher UV levels are more potent" - ed rosenthal cannabis growers handbook.
