Estimating Running Time | Battery Power for LED Pixels
29/7/2012 · LED current use is measured in milliamps (mA). As a rule of thumb, we usually use 20 mA as a guideline for a single LED at full brightness, and each color “pixel” contains three LEDs (one each for red, green and blue), for a total of 60 mA per pixel when displaying white at full brightness.

A long life in the fast lane: positive association between
Studies on long-lived mutant strains have shown that low metabolic rate is not a requirement for long lifespan (Marden et al., 2003; Van Voorhies et al., 2003). In addition, some very long-lived species do not appear to possess exceptional defence mechanisms against oxidative damage ( Andziak et al., 2006 ; Speakman and Selman, 2011 ).
