This product requires a DC 5V power adapter. Incompatible power parameters will cause equipment malfunction or damage: If the input current is lower than the standard value, the lamp may not light up properly; if a power adapter with a voltage higher than DC 5V is used, it will cause the lamp to flicker, and in severe cases, burn out internal components, affecting the product's lifespan.

The lamp body you received has an extended height (≈20 cm), which can be replaced with an actual maximum height of ≥30 cm. The actual height can be freely adjusted.
