This string is actually very impressive for running at such a low voltage. Unlike the 24V version, this string does use fairly standard replaceable low voltage lamps.

It has lots of potential for use as a solar or general off-grid set of lights that put out a useful amount of light. It's probably a cost effective way of buying just the 5V lamps alone for other uses.

I put more information, including tests at various voltages, in the video description.

Very nice low-voltage lighting festoon

This is a string of 10 outdoor festoon lights that is designed to run on a 5V power supply. It's actually surprisingly bright for its total of 5 watts and would provide acceptable illumination in a dark outdoor area. The filaments are not being driven hard, so they should last a long time. Although it comes with a touch controller, it can be replaced with a direct connection or switch for simpler control or for use with a USB PIR sensor module. The lamps/bulbs/globes themselves are quite interesting because they have a plastic globe surrounding a standard glass filament support and the globe is crimped into a standard E27 style base. The internal resistor is 12 ohms, and both the 3V filaments are in parallel. These lights would be perfect for camping, living off grid, emergency lighting or anywhere you wanted a safe low voltage string of lights. They'd also work well on a tree, indoors or out. I tested the string of lights at different voltages:- 5V - 1000mA 4.2V - 600mA 3.6V - 400mA 3V - 165mA 2.5V - 12mA A power pack based on a couple of decent 18650 cells (or a 5000mAh pouch cell) and a TP4056 module would run these lights for well over 10 hours per charge.
