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.

- Aputure COB 120t Features CRI97+ and TLCI97+, excellent color reproduction, display natural, pristine color in both photo and video applications.
- The LS C120t integrates 324 powerful luminous chips, with Bowens Mount Reflector attached, provides 11100lux in 0.5M(1.64ft), ideal light source for photographers and filmmakers.
- Ultra Silent Fan, Noise Low to 18dB. COB 120t has a remarkably intelligent temperature control system. The fans rotation will be varied based on the correspondent ambient temperature. Furthermore, the fans will go to the maximum of rotation when you press the Auto/Force model. This complex fan system is convenient for both improving the dissipation efficiency and light lifespan in complex shooting environment.
- Portable and lightweight, weights 3.5lb similar to A Macbook Pro. Practical Assisted Handgrip is very convenient to adjust the light direction. 2.4G FSK wireless control within 100M, no blind angle.
- Featuring a Tough Aero-Aluminum body, the LS C120t is remarkably tough and durable. It undertakes more than 100 fabrication procedures such as extrusion, cutting, trim, sandblasting, oxidation, laser engraving, etc. The delicate design and elaborate production makes the LS C120t fashionable and robust.
