What this book light is and who it suits

The rechargeable clip-on book light uses a 700mAh battery to deliver up to 140 hours of runtime. It is designed for readers who want a portable, eye-care lamp for bedtime, study or travel without needing a nearby power outlet.

What the colour and dimming controls change

Three colour temperatures are available: 1800K amber for low-stimulus evening reading, 3600K natural for everyday use and 6000K cool white for focused work. Stepless dimming plus five preset levels let you adjust intensity from a subtle glow to brighter illumination.

Practical limits of the sunset mode and timer

Sunset mode runs for a fixed 30 minutes, shifting colour from 6000K to 1800K and brightness from 60% to 15% during the final five minutes. The transition cannot be disabled or customised, so readers who prefer a constant colour or a different fade duration cannot use this function.

Questions about this item

How long will the 700mAh battery last before it needs replacing?

The 700mAh rechargeable battery delivers up to 140 hours of runtime on a single charge, depending on the brightness setting you use.

What limits runtime during a single extended reading session?

Battery capacity is the first limit; the light runs for up to 140 hours on one charge, so very long sessions will eventually require recharging via USB-C.

Does the clip-on light get warm or draw much power when left on all day?

It uses a low-power LED design with three colour temperatures (1800K, 3600K, 6000K) and stepless dimming, so heat and power draw stay minimal even during prolonged use.
