My local Costco (Woodlands Texas) is selling Feit 4' 2-tube LED lights for $19.99. 42 watts, 4000K, 3700 lumens.

I think the sale ends in a few days, sorry I don't remember the date. Limit 10 per customer. I took 10 home yesterday and will probably go back and buy 10 more. I need 30 lights for the new shop and I can't even find decent fluorescent fixtures for this price.
