This is so cool. Not the prettiest thing to look at, reminds me of a spaceship, lol.  Anyway, The lower level in my home is also my workout room.  Even tho I have it well lit, and it has natural light, it still seems dim.  Not anymore.  I like the fact that I can position the lights where I want them.  I have one positioned on my treadmill one on my weight bench and the other directly on the floor.  No more dim workout room.  I'm not sure how long this light will last, but it is inexpensive enough that I can always replace it if it only lasts a year or so.
