Amazing light, a total beast

I bought this as the main light for my garage. It replaced an old 4 tube fluorescent fixture, and since this one is also four tubes I expected a similar lighting effect.

But actually, this one is so much brighter than the old fixture, and the positioning of the bulbs throws light across a much wider area.

The light is quite bright and white without being too harsh. It transformed how I am able to use my garage at night.
