The guide number for the Canon 244T is 53 in feet or 16 in meters.

I borrowed a flash meter (Seconic 508) and tested the 277T, 300TL and a 577G. The 277T was 19, the 300TL a tiny bit higher and the 577G at 32 (and should be 48).
But the flashes gives good exposure at full, so the 27/30/48 number are actual useful.
The surprice whas what distances the auto was working at. The 277T and 300TL could be worked directly not closer than 2-3 feet before you have to dampen them. The 577G could not go closer than 5 feet!
