Cheap and does the job
Size: 6 Feet
Seems to be well constructed, it’s a little thinner than I expected, but it passes bass just fine to my SVS PB 2000 Pro.

Great value for high quality lights
Size: 2Pcs 7.6Inch Light Bar
These are really nice lights. Night and day difference between these and the cheap Nilights. They should really try to differentiate these in their listings.
Nice consistent beam pattern and color. High quality build. Power output close to claimed rating.
