Is $349.99 a good price for the Eufy S4?

It is the only new price listed as of November 7, 2026, and it sits at the top of the recent range. With one store selling it, there is little to compare against, so waiting for a sale is reasonable.

How much coverage does 100 ft give?

100 ft is enough for most single-story rooflines and many two-story front facades. Measure the run you plan, including corners, before buying.

Can it stay up all year?

Yes. The IP67 rating is built for permanent outdoor mounting, and the system is designed to be left in place through the seasons.

Eufy's permanent lights rely on their control module and app for scenes and motion features. Check that your Wi-Fi reaches the install point before mounting.

The kit includes the 100 ft light run and its control hardware. Mounting clips and any extension cabling should be confirmed with the listing before you buy.

How does it compare with regular string lights?

It costs far more upfront but installs once and adds app control and motion sensing. String lights are cheaper but come down and go back up every year.
