It’s definitely NOT the brightest available, but it will be enough for many occasions. This model has 3 brightness settings, accomplished with two sets of LEDs, and turning them on one at a time, or both on together. One set has a warm color cast, and the other a neutral or cool white cast. Would be more effective and less distracting all the same color cast. Seller states clearly that light us not waterproof, so take it down and keep indoors when umbrella is lowered. This model fits onto thick wooden umbrella poles, in addition to thin metal ones. Awkward plastic clip needs to be opened to take down light; may break fingernails, and thin plastic of clip may break over time. But for now, with low price, I’m happy for now!
