PEVOROS Solar Fiber Optic Firework Garden Lights, Pair

This two pack of solar fireworks stakes uses a small photovoltaic cell to charge by day and fiber optic strands to scatter light by night. The listing lists two lighting modes plus off, a ground stake for placement, and a claim of waterproof construction, though it gives no rating or duration figures.

The lights work on a simple principle. A solar panel converts daylight into stored charge, and after dusk that charge powers an LED that sends light through bundles of fiber optic strands, producing the spread of color the listing describes as a firework effect. No batteries need buying or replacing, since the sun does that job, though output on short winter days will depend on how much light the panel actually receives.

A three position switch offers two lighting modes and an off setting, and each unit comes with a ground stake meant for a lawn, flowerpot, or garden bed. The listing notes the stems can be bent into shapes such as hearts or stars, which suggests the fiber strands sit on a flexible wire core rather than a rigid one.

The listing calls the product waterproof but does not specify an ingress protection rating, so how it performs through repeated rain, frost, or a full winter outdoors is not something the material addresses. Anyone planning to leave these out year round would want to check the solar panel and stake material hold up to freezing and thawing, since that is usually where cheaply sealed outdoor solar lights fail first.
