SKU CH-HFPY-1KGZM

Ultralight 1.3 oz clip-on light with 360° gooseneck, 3 colour temperatures, stepless dimming and 80-hour runtime

  • 80 hours runtime on a single charge
  • 3 oz weight adds hardly any bulk
  • 3 colour temperatures with stepless dimming
  • 2 in padded clamp grips without marks
  • 360° flexible gooseneck positions light precisely

Lightweight Clip-On Reading Light

The Monotremp rechargeable book light weighs 1.3 oz and clips onto books, e-readers or tablets with a 1.2 in opening padded by soft sponge. Its 360° flexible metal gooseneck holds position without shaking, and the foldable design packs smaller than a phone for travel. Three colour temperatures and three brightness levels let readers tailor illumination for bedtime, study or commute.

Simple Setup and Common Issues

Charging via the included micro USB cable takes 1.5 hours for a full battery. Operation uses a short press for brightness and a long press for colour temperature, with a memory function that recalls the last setting. The clamp suits thin objects only; thicker hardcovers or bulky cases may not grip securely, and the micro USB port is the sole charging interface.

Sustained Use Behaviour

The built-in battery delivers up to 80 hours of runtime on the lowest setting, dropping proportionally at higher brightness levels. LED output remains flicker-free and even across the discharge curve, avoiding eye strain during long sessions. The metal-sheathed gooseneck resists fatigue from repeated repositioning, maintaining aim without droop over extended daily use.

Questions about this item

How do I confirm the light runs for the full 80 hours on a single charge?

Fully charge the unit with the included micro USB cable for 1.5 hours, select your preferred brightness, and time the session; the battery should last up to 80 hours on the lowest setting.

What accessories come in the box and what must I supply?

The package includes the book light and a micro USB charging cable; a USB power source such as a computer port or wall adapter is not included.

Which of the three colour temperatures should I choose for bedtime reading?

Use the warm light setting — activated by a long press — to reduce blue light and avoid disturbing a sleeping partner.
