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).

Kinda of a cool gadget

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

Love the Warm Glow!

Color: Warm White

This light is very easy to install and has 3 different lighting options. I love the warm white light it emits as opposed to a bright white light that could attract bugs at night. Perfect light for patio, deck, camping, golf cart, etc!

It feels cheap and works just okay

This product just feels like it was made on the bottom dollar. It is very cheaply made and the doors to the battery compartment are so fragile it feels like they may snap next time I have to change the batteries. There's absolutely no weather proofing so I wouldn't leave it outside in the rain or heat. That being said, it's fine. It stays put on our umbrella and puts out light, albeit not much light.

Functional and easy to install!

Color: Cool White

This umbrella light is super handy! It hinges open to allow installation around the umbrella pole, so you don’t have to remove umbrella from table to add the light. I like that it can be charged with included USB cord or can use regular batteries. The different light settings are also nice depending on how much light you need or want at the time. We’ll be using this quite often when sitting at the table by the pool this summer.
