The link probably works for you because you have a Sam's club account. I don't have an account and my computer does not automatically log me onto the link. It still doesn't work. Sorry.
Worked for me.
Here's some info from the webpage.
Honeywell LED 4' Shop Lights (2-Pack Silver Finish)
by Honeywell | Item #: 465390 | Model #: SH445501Q299
They were $55 plus change for the two fixtures.
I got my led tubes from Costco for about $17 for a pair. They work in any old fluorescent fixture.
