The 86\" (silver lining) PLM is lighter than I expected it to be. Construction isn\'t flimsy just light weight. The 8mm diameter shaft is shorter than the the rib length . There are 16 panels so the perimeter is closer to a circle than an eight panel umbrella, \"brolly box\" or the Octalight. It looks like a giant but shallow umbrella.
First test: (efficiency):
1) measured with a Sekonic L758dr in incident mode
2) Light source: Elinchrom Quadra + a Quadra A head (no reflector) in the A channel. Output set to 400 watt-seconds. (Just because Elinchrom\'s management chose to go with a non-industry standard umbrella shaft size doesn\'t mean there aren\'t ways to easily solve the problem with out resorting to having the shaft replaced or machined down --but more about that in another post). flash triggered by Skyport.
3) fired flash 10 times with 6 seconds between firings
result: f/16.0 @ 10 feet , meter set to IS0 100 and 1/125th second.
