The BrightFlex® was created as a multi-purpose upgrade to our original, industry-standard Orchestra Light. No longer just for musicians, we've made this light even better with a compact design that provides the same brightness via a streamlined light head, plus a battery bank capable of providing at least a 50% charge to a standard smartphone. 8 LEDs provide 90 lumens of bright white (5000K). 3 brightness settings with 8 hours of battery life on high, 45 on low. Battery bank provides a 50% charge to a standard smartphone. 5V1A output, charges in 3.5 hours. 2500 mAh capacity.
