Direct sunlight or a strong light lamp is perfect, but the best is UV light. The stronger the light is and the longer it's left under the better and longer-lasting the glow will be. The pendant will glow in evening conditions fading out over the first hour but still containing enough energy to glow in the dark for hours.
