Thank you for viewing. Camp Grieve Rope Light LED Lights Waterproof, set of 10 Continuous illumination for 300 hours (when new) Comes with a dedicated case Color: Yellow (Orange, close to incandescent) Of the set of 10, 5 are unused. The 5 used ones were only used once, so I think they can still be used for over 250 hours. How about using them at night to prevent falls?
