Underground wiring from new light to house

I'm installing a new ground light (Red-Dot) on my lawn
The lamp comes with 2' PVC post to bury below the surface
I'm using 14/2 UF and will bury the UF 24" down
I plan to use a weatherproof box on the side of the house
How do I bring it up out of the ground for connection to the house?
Should I use 1/2" PVC extending from the bottom of the WX box and extend it into the ground 24" and bring the UF up through the PVC?
Can the UF run directly through the PVC conduit (Code question?)
Any need to seal (or use connectors) on the underground ends of the PVC ?
Many thanks,
Bill

Bill, yes, you would use a 1/2" pvc (gray) sweep, taking the sweep to your 24" depth. It is best to use a 1/2" piece of pvc with a bell and invert it onto your sweep to give you the depth. It is not against code to use the pvc, just a major PITA to run it any length.

A little more explanation...

Ok on PVC down 24" and sweep it out horizontally underground
What do you mean by a "bell"?
Should I use putty or silicone seal when the UF enters the PVC?
I'm almost there with how to do this properly
Many thanks,
Bill

The "bell" is the end of a 10 foot length of PVC conduit that is the coupling end. It used to be that one end of a 10 foot length had a coupling glued on at the factory, but today one end is heated and flared to the proper dimension for a coupling and that is commonly referred to as the "bell" end. No sealing is necessary where the UF enters the conduit 24 inches beneath the surface.
