Daisy-chained & individually programmable RGBW LED floodlights

You only need one power outlet to enable the whole set of six floodlights. Then you don't have to buy extra extension cords to hook them all up. This makes installation far easier for the average homeowner. As we work with the Smart Life app, just simple taps on the mobile phone allow you to control each light separately even when you are not at home. 

1 cord, 6 lights. 10' of cord between them. 

With near-infinite customization options, you can use them individually if you so desire. You can choose 16 million colors for ambient decoration and 2700K warm white for daily use. And whether it’s to create a fun atmosphere or serve an illumination purpose, scroll through colors and settings to pinpoint your style or mood, and no complicated wiring required.

Patented exclusive design 

The LED diode cover is made from a textured glass with an anti-glare design, showing off your modern aesthetic in details. This is better for diffusing light and protecting eyes. The light emitted is also softer, creating a gentle atmosphere. The bracket can be rotated up to 360 degrees, which supports various angles of wall and ground installation. 

RGBW color range  

While most of us know that RGB – Red / Green / Blue – you might not have heard of the W part at the end. This is an acronym for warm white, and 2700 Kelvin (2700k) has a much warmer feel to it and tends to mimic the warmer tone of a traditional halogen light bulb. You can set your GemBand warm white to greet you as you come home.

Voice control / Group control

"Alexa, dim the light to 50 percent." Use Amazon Alexa or the Google Assistant to turn your lights on and off, dim them, and more. This is especially great at night when you’re ready to go to sleep – all you have to do is using your voice to turn off the lights from the comfort of your bed!

Dance to music

With built-in IC, the colors of six flood lights could 100% sync with the rhythm and beats.  It's definitely a fun party trick, or an easy way to have a dance-off with your cat. Choose any music mode in the app to turn your favorite songs into a show of color and light,  and feel every beat like never before. 

Sync to your daily schedule

Preset in the app according to your daily schedule and make lights a part of your habit. For example, you can set schedules to automatically turn off on 11pm , in case you forget turning off them. And when you're out, use them to make others think you're still home, which gives you peace of mind whether you're home or away.

Born for holidays

No toil. No trouble. All for holidays. Blue, green and purple spot lights add the perfect spooky atmosphere for your front yard Halloween cemetery or yard haunt. And you can add orange and red lights as the accent colors since they contrast well with the blue and green. With convenient control and endless possibilities, you can match your GemBand floodlights to your surroundings and get unique ambiance easily.

Ultra environment resistance

The IP66 is in reference to the Smart LED Flood Lights’ weather-resistance rating. The first “6” indicates a high level of dust-resistance. Indeed, the housing is practically impervious to dust, and won’t get damaged even in a dust storm. The second “6” indicates a medium-high level of water-resistance. In fact, it’s the highest level of water-resistance you can have without being fully submersion-proof. (The power adapter is IP44 rated waterproof.)
