Looking for electricians knowledge on 4’ Florissant bulbs

Put a single gang box and recep on the run that goes to the fixture, then get a Rural King 4500/5000 lumen LED fixture.

20 min.

$22-$25 and sometimes on sale for $17.

You will notice a drop in your electric bill if you swap them all out.

...but you can just do as needed...for just a tad more than buying new fluorescent bulbs.
