Aputure Light Storm COB 120t CRI97+ TLCI97+ 3000K 135W Bowens Mount High Power LED Continuous Video Light – 18dB Low Noise with 2.4G Remote Control and V-Mount Plate – Carrying Case Included

Question: the Ls1s is advertised as nearly 1k equivalent and outputs around 30k lux at a half meter, but the COB120t is advertised as nearly 1.5k equivalent
and outputs only around 11k lux at a half meter according to the spec chart. Is it just because of the light angle or what?

Answer: These measurements are at a single point. The LS1S is a 25 degree beam angle and is being compared to the 120T which is a 120 degree beam angle.
That’s about five times the coverage in terms of angle. When we measure output, it’s about measuring the total output, each and every ray of light that comes out of these units.
Aputure will be releasing a video to show how to measure total light output soon.
