All flashes were testsed at full flash power. Modeling lamps were switched off.

 

 

 

 

 

 
The testing procedure includes the use of the "additional energy" procedure (see 2. and 3. bellow), which extends autonomy for additional:
7 - 25% (typically 15%) with FlashFeeder COMPACT connected to one Compact Battery Case (more additional cases can be connected in chain)
(Unlimited number of additional Battery Cases can be connected in chain)

 

 

 

 

 

 
Testing procedure: 
 

 

 

 
1. The flash unit (at full power) was triggered at regular intervals (see formula below) until the Flash Feeder stops automatically (red "LOW INTERNAL BATTERY" indicator is on and the unit is beeping continually). The unit was switched off manually.
2. After 30 minutes the procedure (1.). was repeated.
3. After adittional 30 minutes the procedure (1.). was repeated.

 

 

 

 

 

 
Formula for calculating the regular intervals (in seconds) between flash
triggers: FLASH POWER (Ws) : 100 = INTERVAL (seconds)

 

 

 

 

 

 
Example: For 1200 Ws flash unit the flash was triggered once every 12 seconds (1200 : 100 = 12 seconds).
