LEDs to replace Fluorescent Tubes

[buzzclip]

I have a 222 with has a 28" T8 and 28" T12 fluorescents. It looks great but there's a very audible hum from the bulbs, particularly the T8. Has anyone had luck replacing those with LEDs? I found a T8 replacement on Amazon (https://www.amazon.com/dp/B07L2S2LZM?_encoding=UTF8&psc=1&ref_=cm_sw_r_cp_ud_dp_MP2W61S67NS28HGXDM7G).
But will it work with the original ballasts? I don't know anything about ballasts. If LEDs aren't the way to go for these machines, could I mitigate the hum with a new fluorescent bulb or new ballast?

I'm pretty sure both lamps should be T12's.
