Amber 1800K reading light

This clip-on book light emits a warm 1800K amber glow that blocks 99.95% of blue light to protect eyes and avoid disrupting circadian rhythm during bedtime reading. Three brightness levels at 30%, 60% and 100% let the user match the light to the environment without disturbing a partner. The built-in rechargeable battery provides about eight hours of use after a 1.5 hour charge via any USB port, removing the need for disposable batteries. Its compact 1.38 ounce design folds flat to double as a bookmark for travel.

Thermals noise and power

The LED runs cool during normal reading sessions so the clip and flexible arm stay comfortable to handle. Silent operation with no fan or moving parts means zero audible noise in quiet bedrooms. Power draw is limited to the low-current USB recharge cycle of 1.5 hours, after which the light operates untethered for roughly eight hours at the chosen brightness setting.

Sustained load behaviour

During extended use the amber LEDs maintain consistent colour temperature and output without noticeable dimming or flicker across the full battery discharge. The 315° flexible holder and 90° horizontal plus 45° downward lens swivel retain their position without sagging, so the beam stays aimed at the page. Brightness memory returns the light to the last selected level each time it is switched on, avoiding repeated adjustments during long reading periods.

Questions about this item

How do I clip the 1.38 ounce light onto a book without damaging the pages?

The transparent clip side slides onto the page edge while the sturdy metal arm grips the cover; the clip opens wide enough for thick books yet applies even pressure so pages stay flat.

What charging cycle does the built-in USB battery need to keep its 8-hour runtime?

Recharge fully in 1.5 hours from any USB port — laptop, power bank or wall adapter — and the cell holds enough energy for roughly 8 hours at the 100 % brightness setting.

At which brightness level does the 1800 K amber LED run longest before the battery gives out?

The 30 % low setting draws the least current, so a single charge lasts well beyond the 8-hour figure quoted for the 100 % level.
