Excellent lighting
Color: Warm
Highly recommended!
I actually reordered one because I forgot one night to bring it in, then a severe storm came through and stole the umbrella, turning it upside down in the yard. Water got into the battery bays, so they rusted. I'm sure other connections inside rusted too, because after cleaning the contacts, I could not get the light to work again.
But the reason I purchased a new one is because it looks so classy. Its warm light can be adjusted to three levels just by pressing the On button through the levels. Very simple. The ambiance it provides is lovely!
Next to the On button is the clip that flips open to swing open the light. Place the light around the umbrella pole and snap shut the clip. The light is secured, but you can also slide it up or down to whatever height you prefer. It still remains stable and in place until you move it again.
Until I left my first one out in the rain, the light worked beautifully and reliably, as does its replacement. Battery life is excellent unless you forget to turn off the light. I can't tell you exactly how long they last because inevitably after a few weeks, I do forget to turn it off.
This is an inexpensive and beautiful upgrade to your patio experience. Excellent value, excellent quality, excellent lighting.

Great light, great price!
Color: White, Color: White
I'm a Carnivore who does all of my meat and fish cooking outdoors, adjacent to my kitchen. For the winter, I've put up a half-umbrella to keep the rain off of my cooktop. This light rounds out the kitchen by providing GREAT light for my alfresco kitchen. It works like a charm and is easy on the batteries.. I LOVE it!

Good price, easy to install
Color: Warm
First, the price is right. It is easy to install. My biggest problem was within a few hours, one of the bulbs already burned out. We are still using it and the rest work great.

Great Invention
Color: White, Color: White
So simple to install and we absolutely love having this light on our patio table. You can adjust this light anywhere on the pole and direct the lights to shine up or down depending on your preference. It also has three settings. It is well made and runs on 4 AA batteries. This is a great invention and several people that have seen this light have ordered one for their own patio tables.

Bright, easy to use
Color: White
Love that you have different light settings. Perfect lighting. Fit easy and perfect. Only downfall is you need 4 batteries. Not had it long enough to know how long it will last. Would buy again.
