The 4' twin tube fluorescent uses 64 watts and pumps out 5700 lumens of

The 4' LED version uses 50 watts and only puts out 4000 lumens, for $109.

Are you sure about that wattage?
My LED yard light only uses 18W. Replaced a 175W mercury vapor bulb.
I dont know the lumens, but the LED is brighter.
I'm sure they go on sale at times too..... Plus where are they $109? I'm
sure I've seen them at Menards for much less....
