Compact USB Rechargeable Reading Lamp

Form factor: minimalist linear profile, 4.3 inches long; Mass: 42.5 g (1.5 oz); Energy source: embedded Li-Po battery, USB-rechargeable, 800 mAh; Operational range: 5–100% brightness, infinitely variable; Light characteristics: 4000K neutral white, flicker-free, no UV/IR emission; Mechanical design: reinforced polypropylene body, stainless-steel clip spring, silicone grip pads; Certification: RoHS, REACH, UKCA-ready documentation available. Engineered for readers who switch between formats — print, e-ink, and backlit tablets — the lamp maintains consistent colour rendering and minimal screen reflection. Its neutral white spectrum avoids the ‘blue spike’ common in cool-white LEDs, supporting longer evening use without disrupting melatonin production. The clip’s calibrated spring tension ensures firm attachment without damaging book spines or leaving marks on device casings — validated across 200+ cycles of repeated mounting/unmounting. Every unit undergoes individual brightness calibration and flicker verification before dispatch from our UK fulfilment partner.
