Can they replace utilitech l72053 flouresant bulb? for under kitchen cabinets.

Yes they work very well and are a direct replacement

Is the G-53 lamp base part of the light or purchased separately?

These are replacement bulbs so the lamp base is not included

Can they replace bonlux led 5050smd ?

Sorry I do not know that answer. I used the Gx53 to replace some florescent type that couldn't take the cold outside. I will say that the Gx 53 is a full power 110volt AC bulb. Most under the counter lights are knocked down to a low volt DC.
