What to know before buying
Listing details to confirm
Battery runtime is a manufacturer claim and depends on brightness. The 80-hour figure applies at the lowest brightness, not high output. The listing also has inconsistent control descriptions, identifying both touch control and a push button, and lists Bluetooth without explaining its purpose. Confirm these details and charging-cable inclusion on the selected listing.

Customer feedback describes the clip as useful and highlights adjustable brightness, three color temperatures, a long-lasting rechargeable battery and an even glow. Those reports fit the listed clip mount, three lighting modes and brightness control. The listing's runtime figures are mode-dependent, so the reported battery satisfaction should not be taken to mean the maximum runtime applies at high brightness.
