Review on PowerSmith 20,000 Lumen LED Work Light With Adjustable Metal Tripod & 5 Year Warranty by Adam Nikolz

last year i bought the 4000 lumen version of this fixture and it performed admirably while i was rebuilding a building i lost in the 2017 fires. so, when i needed another lamp i saw this 4600 lumen version for a few dollars more i purchased it. what i received was a fixture with 2-23 watt bulbs, while my previous fixture had 40 watt bulbs. i am confused as to how the fixture with less lumens had higher wattage bulbs than the fixture with more lumens and how this whole rating system is represented. check photos for comparison. i will keep fixture because it is adequate and not worth the trouble to return, i just feel the description is either misleading or confusing. i would like to hear manufacturers explanation.
