Hey Everyone
I must just be doing something wrong or my lightmeter is wrong but I was testing my 800w open face lights today between a few brands I have and noticed that my own Arrilite 800w Open faces put out considerably less light than what Arri's photometrics says they should?
Arrilite 800w at 3ft away pointing directly at the lightmeter dome Recessed inside not out, settings (25fps, 800iso, 180d) 240v
Full Flood I got a 340fc , Arri's photometrics say it should be roughly 537fc
Full Spot I got a 2200fc, Arri's photometrics say it should be roughly 9871fc
Is there something I'm doing wrong? I checked the bulb, Cleaned the dome results are the same
I understand photometric arnt 1:1 but mine seem so far off
Thanks
