   Having a hard time wrapping my head around this.
   The 26 has that number of LEDs at the specified types.
   The 52 is the 26 times 2. Same LEDs but twice as many of each type.
   The 26 uses 90 watts.
   The 52 uses 135 watts.
   
   WTF am I missing? Twice as many leds equivalently, only 50% more energy.

   I maybe wrong but I believe the 52 also uses more narrow optics for penetration.
