Expectations exceeded (and illuminated!)
I am so stoked about this purchase. Our outdoor lighting situation was terrible- motion-activated lights that cut out after ten minutes and zero power outlets outside. This umbrella light exceeded every expectation. Three brightness modes, all bright enough to actually see what you’re doing — no more squinting while socializing, reading, or attempting to do “work” outside. Cordless, easy to install, and long lasting. If you consistently forget to turn them off when you're done, you'll get about a week and a half from the batteries on the lowest setting.
