| Type | Needs power? | Glows in total darkness? | How long |
|---|---|---|---|
| Phosphorescent (your resin animals) | No — charged by light | Yes | 4–12 hours, fading |
| Fluorescent / UV-reactive | Needs a blacklight on | No | Only while lit |
| LED / battery figurine | Battery | Yes | Until battery dies |
| Solar garden light | Sunlight + battery | Yes | 6–8 hours, until battery wears out |
This is the honest reason collectors love mini resin animals: no batteries to replace, no wires, no charging port, and nothing to switch on. The light you already have in your home is the fuel.
