Oh, the wide world of wonderful succulents!  They can be so easy and fascinating to grow.  Most varieties will thrive given bright light and little water.  However, there can be a remarkable difference in how they respond to growing them outdoors vs. indoors.  When indoors, they often get leggy and tend to rot more rapidly.  With the Procyon series of lights, they remain healthy, with dense foliage and beautiful coloration all year long.
