Chinese tariffs? I went to Amazon to purchase another F54T5 light fixture (20000 lumens) and the price is now $100. It was about $70 when I bought the same thing 2 years ago. I checked at some commercial lighting places, like prolighting.com and their prices have similarly gone up. I did find one for $67 but it doesn't include the lamps, plus shipping is $17. Equivalent LEDs are hard to find and even higher.
