Note: To determine the maximum number of any LED products on a single Power Supply - take current draw @ 12 Volts DC (listed in more info sections) in milliamps and divide that number by the output rated current of the specific power supply (in milliamps) - then multiply that number by 0.9 (for 90% capacity)
* Maximum number of light bars in one run (end to end) - for higher quantities, multiple runs back to the power supply must be made to prevent excessive voltage drop
** WFLB series Light Bar does not have end to end capability
*** RGB-CA12 uses direct connect to Compact Power Supply DC in jack
