A number of recent threads have been about replacing fluorescent shop lights with LED. A number of you have recommended the Feit LED shop lights sold at Costco. I received my Costco Savings Coupon Book in the mail yesterday, and it announces that starting on April 17, those Feit 4-foot LED 4K will be on sale for $19.99 (usually $29.99). The book also says that Costco.com will have additional savings on the 2-packs (though the web site doesn't identify what the savings will be as of today; presumably it will starting Tuesday). I think it's time to bid farewell to my fluorescents.
