I grow in a small closet (22x43"), and this bar light is ideal. It dumps tons of light but doesn't take up space. Enhanced red wavelengths make my flowering plants thrive-harvested 1lb last cycle! Dimming is easy, so I never worry about burning. Stays cool, installs in 10 mins, and the build quality feels solid. Love it!

Had this SP 3000 for over two years, and it's still going strong. Used it in a 2x4 tent nonstop-yields are consistent, and it's super energy-efficient. Recently had a minor dimming issue, and Mars Hydro's support helped right away.
