    Bright, Versatile, and Easy to Use!
    Color: Warm White
    This Dual-Power Patio Umbrella Light is exactly what I needed for evening gatherings! I love that it works with both rechargeable and regular batteries—super convenient. The three lighting modes are perfect for setting the mood, whether it’s a dinner party or just relaxing outside. It clips easily onto the umbrella pole and stays secure. Great for patios and even camping. Definitely worth it!

    This little light is bright!
    Color: Cool White
    I was looking for a light to hang with my outdoor table that has an umbrella. I did not know this was a thing! But I am glad I found it! It fits perfect, snaps right on. The light is bright enough to see the entire area located under the umbrella. I am unsure how long the battery life works as we haven't stayed out past dark more than an hour or so, but it has worked every day for a week! Awesome product, awesome idea! Why didn't I think of that!?! Totally recommend this little light!

    Great little umbrella light, I love it!
    Color: Warm White, Color: Warm White
    This umbrella light is small , compact and very lightweight, you can effortlessly move it around if your changing umbrellas. I Also love how bright this little thing is, with the click of a button the place is brightly lit. Love, that you don't have to have all the lights on if you don't want to that's a stand out feature. Great little light that adds a touch of elegance. Very user-friendly, in seconds to minutes its up and running.

    Great Light but NOT USB CHARGEABLE
    I bought this lamp for my bell tent, which has a center pole. It did exactly what I wanted it to do: provide light to my whole tent instead of depending on a lantern or flashlight. It snapped on easily and fit the pole perfectly. I wish it had a remote but I could have spent more and bought one with that functionality. The reason I took a star off is because it is advertised as being USB and even requires RECHARGABLE batteries. Since I'm not savvy on these things I paid extra for the batteries thinking the USB charges them in the device. NOPE. The USB is just for powering the light from an ac source (which is pointless for what I use it for).

    Color: Cool White
    I really didn't know I needed this until I got it! Easy and quick to recharge batteries (they do not come with rechargeable batteries). Put out enough light for an evening outside around the table
