When you need personal light, this hands free light delivers features and practical usefulness unmatched by other portable lights. Invented and patented by ASF Lightware Solutions it features: extra wide & extra bright light from 6 LEDs, 2 clip-on Relaxation Filters, longer battery life, and an optional external Power Kit. 
It's a true reading light that works with all Kindles and other eReaders, printed books, PLUS newspapers, loose documents, maps and other items that can' t support a clip-on light. Worn around the neck, it shines a cool & steady light for reading, quilting, knitting, all needlework & crafts, and searching a dark basement. Use it for writing journals, working, camping, and changing diapers at night. 
The extra bright light is helpful for those with aging eyes. Included are two 2 special Relaxation Filters that snap-on the light: BNR Orange for a softer, warmer light and to block blue light; BNR Red to block blue light, reduce ambient light for sensitive bed partners, or to help maintain night vision. A switch lets you light all 6 LEDS or just 3 LEDs. 
4 alkaline AA batteries (not included) will run for 50 hours shining all 6 LEDs or 100 hours when using 3 LEDs. The longer battery runtime than other lights is especially valuable during a power outage and when traveling. This light is still bright when others have gone dim.
