Thin-Lite LED light fixture?

This is Thin-Lite's LED version of the popular fluorescent model 626 and P2626 lights.
Amp draw of 0.40 to 1.25 amps (4.32 to 14.4 watts), lumen output of 720 to 2400 lumens.
Note: the standard fluorescent model 626 draws 2.2 amps and outputs 1650 lumens.

I wonder why the power for the LED varies so much? LEDs with no voltage regulation certainly draw a lot more power at higher voltage. Our cheapo $3 LED panels draw 7 times less current than incandescents on 12.6 V battery power and they are barely warm to the touch. But on shore power the voltage goes up to 13.6, the LEDs draw three times as much current and they get HOT! No doubt it greatly reduces their lifetime. If I was paying $80 a fixture, I would expect and demand voltage regulation to eliminate the problem.

Incidentally, i recently learned that the price of T8 fluorescent bulbs is far lower when I buy them by the boxful at Home Depot. And a four foot fixture with electronic ballast is about $30. I am replacing the old ballasts in our house as quickly as I can because the electronic ones are more efficient, never buzz, handle cold much better and they don't have that nasty tar that sometimes leaks. I find it is no more expensive to replace the whole fixture.
