Charges in light and glows in the dark; easy to find at night.
What it is
Lume is a glow-in-the-dark material that absorbs light and releases it slowly in the dark. Modern lume is usually based on strontium aluminate pigment, mixed into resin or plastic and used as inlays, filled grooves, beads or buttons. It is different from tritium, which glows without charging. Brightness, color and glow time depend on the pigment quality, amount and the maker.
How it feels in your EDC
Lume adds a fun, practical touch, helping you spot your gear in a dark bag, drawer or nightstand. It glows brightest right after charging in sunlight or under a bright light, then gradually fades over time. In daylight, lume usually looks pale green, blue or off-white, so it can also serve as a subtle accent color.
Care & aging
Lume can be recharged again and again by exposing it to light. Keep it clean with a soft cloth and mild soap, because dirt can dull the glow. Avoid strong solvents, high heat and abrasive polishing, which can scratch or cloud resin-based lume. Its charge-and-glow performance may gradually change over many years.
是什么
夜光（Lume）是一种能吸收光线、在黑暗中缓慢释放的发光材料。现代夜光通常以铝酸锶颜料为基础，混入树脂或塑料，用作镶嵌件、填充凹槽、珠子或按键。它与氚不同，氚不需要充能就能发光。亮度、颜色和发光时长取决于颜料品质、用量和品牌。
上手感受
夜光增添有趣又实用的一面，帮你在漆黑的包里、抽屉或床头柜上找到装备。在阳光或强光下充能后最亮，之后逐渐变暗。白天夜光通常呈淡绿色、淡蓝色或米白色，也可以作为低调的点缀色。
保养与老化
夜光可以反复见光充能。用软布和温和的肥皂保持清洁，污垢会让光变暗。避免强溶剂、高温和研磨抛光，它们可能刮伤或让树脂基夜光发雾。多年后，它的充能和发光表现可能逐渐变化。
