HID vs LED

When comparing lights, look at their Lumen and their Temperature (in Kelvin).

Lumen is measure of power perceived by the human eye. That is the number you can use to compare apples to apples. If light A is 500lumen and light B is 800lumen, light be is going to appear to be brighter.

That is not entirely correct. Lumens is the total amount of luminous flux emitting from the light source. You can have a light with a small beam angle appear brighter than one with a wide beam angle yet the lumens are identical. I think what you are referring to is Lux. 1 lx = 1 lm/m2.
