It is best to study and read in natural light during the day, and protect yourself from artificial blue light sources if using technology such as laptops, computers, tablets, and kindles. Instead of revealing the exact brightness of these settings, Glocusent describes them as being bright enough for “general reading,” “brighter reading,” and “precise working.” The brighter the setting, the shorter the battery life, and when we tested this light at home, it took more than three days for the battery to die when using a single light in yellow, general reading mode. This dropped to seven hours when both lights were set to the cool white setting, or precise working mode. This battery is rechargeable but note that it will only charge with the cable that comes in the box. Our review model wouldn’t work with any other USB-C line.

Battery life and charging options –Battery life of 24 hours(24 hours in dim mode, 12 hours in medium light and 6 hours in the brightest light). Has a built-inrechargeable battery with USB interface design with a charging time of 4 hours. Apart from brightness level, color temperature is another crucial consideration. Color temperature refers to a system using numerical values to measure the color characteristics of a light source on a spectrum ranging from warm to cool colors. The numerical values can be indicated as degrees Kelvin, noted by the symbol K. In non-specialists saying, color temperature signifies a way of describing the warmth or coolness color features of a light source. For people in the know, they call this the lux figure or simply the number of lumensit can emit on a square meter. For reading,writing, knitting, and working on the computer, this should be between 250 to 500 lumens per square meter.
