Shop lights- New LEDs

Bought two of these 8 ft LED light fixtures to replace the two that got smashed when a tree went through my shop roof

Each 4ft t8 LED tube is 1850 lumens

My old 8ft ballast florescent lights (f96T12/cw/cold temp)were brighter , put out more light/lumens
How could that be ??? the internet says all LEDs are brighter than that old fashioned , obsolete, outdated sheeit

Do you have a light meter or is this a subjective observation?

 

I replaced all mine with LED

much brighter than the tubes

all the lights at school were changed out.
Luv em. Especially in the shop

 

I have a light meter......

 

Not all LEDs are created equal!

 

Because you bought 1850 lumens LED lights instead of the 4000 or 5ooo lumens LED lights.
