I happened to have a couple of different lights at hand with the same emitter, Nichia 519A 5000K. Just a quick comparison of the beam profiles between these lights: Convoy T3 – Convoy S3 – Convoy T6 – Wurkkos FC11C. All with OP reflector.
The outputs are not matched accurately. To sum up:
Hotspot size
T6 < T3 < FC11C < S3
Spill size
T6 < T3 < S3 < FC11C
T3 has a bit tighter hotspot than the S3. S3 has the largest and softest hotspot (applies to S2+ too, same reflector). The FC11C hotspot is similar to T3 but the spill is much larger. The transition from hotspot to spill is much sharper in FC11C than S3. T6 hotspot appears large in the pictures, but that is because it is more intense than the others.
