I bought five Harbor Tools LED four foot lights. And one 3200 lumes from Rockler. The HT are a lot less expensive than Rockler unless you find them on sale.I came looking for a place to offer a review on a purchase UPS dropped off tonight. I'd ordered 5 LED lights from Rockler. They were $15.00 each, with free shipping.
I panicked, seeing the package. The box was about 5" x 6" x 4'. I thought I'd screwed up and just bought tubes that replace fluorescent tubes. It was late and the picture in the ad can be mistaken for the common double tube type fixture (it's on me, I did).
I opened the box, and one of the 5 boxes inside. They were single tube lights in their entirety. I took it to a back room, where I had just installed a corncob LED. I plugged it in and was pleasantly surprised to see it better lit the room than the 30 watt corncob did. [For those unaware, 30 watts is a lot of wattage in the LED world.]
I have twenty-four double 4' lights, of which four are still fluorescent. Thanks to Costco aside, I'm thinking I like these better, for the mere $6.00 bucks more than two of the double type fixtures ran me. With these, I can separate two bulbs, which seems a much better solution to lighting my 30x60 shop.

I could not see a difference between the HT and Rocker's. I'm going to add two LED spotlights in three areas in my shop. None of these 3200 lumin class bulbs give enought light to do intricate work.
But my eyesight is probably different than the OPs.
