What to know before buying

Listing details to confirm

Listing details are inconsistent: the title calls the lights RGBW while the details field lists RGB, and the claim of up to six linked sets totaling 198 feet does not establish how much extension is included with this 66-foot package. Confirm the color configuration and any additional sets needed for your layout. The listing also describes outdoor water resistance without specifying a protection rating.

Frequently asked questions

How long is the included string?

The listing specifies a length of 66 feet and 66 light sources. Its separate linking claim describes up to six sets and up to 198 feet total, so confirm what is included if you need more than one run.

How can the lights be controlled?

The listing names app, remote, and button controls, and lists Bluetooth connectivity. It does not specify further app or phone compatibility details.

Are these lights RGB or RGBW?

The title describes them as RGBW, while the light-color detail says RGB. The exact color configuration is therefore unclear from the listing and should be confirmed before buying.

Can they be used outdoors?

They are listed for outdoor use and as water resistant. No specific protection rating is supplied.
