Bought two of these from Ollie's, they seem decently built.

I bet either the actual wattage is higher or the actual lumens are lower. LED can't reach 100lm/w in a lamp or a fixture and these rating are often the maximum that the manufacturer claim that its product can deliver.

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

I have seen several LED fixtures with fixed LEDs with efficacies over 150 lm/W. Properly designed fixtures are very efficient.

Too many things are secret. Only open information can really preserve old technology.

I like fluorescent and other conventional lighting and old electronic equipment. Today's things are not made to last.

What about losses of the driver and optics?

They were all taken into account and today's electronic PSU losses are not significant anyway. And these 50 W LED fixtures were also significantly brighter than the aged 2*58 W fluorescents they replaced. One interesting Finnish lighting store also tests fixtures and lamps themselves and have proved LED efficiency true. Of course the efficacy of this lamp drops significantly, when it is on a fixture. But as I said, fixtures designed for LED modules have much better efficacy. Today's best commercial LED lamps are reaching 200 lm/W efficacy, and have far better efficacy than any fluorescent lamp. Best efficacy reached with laboratory tests is about 300 lm/W.
