HERE IS THE TK32 NUMBERS
You may NOT notice it unless you have a target at 310m and One at 400m where the MH25 fades and the TK32 continues for 90 more meters!With that said,I would think you may see a little difference in the hot spot if you were ~ 10 or 15' away from a garage[white] or White building and shined them side by side.
40Kcd and 24Kcd "MAY" also be noticeable on wall shots, it will be slight. Try that to see if you can tell the difference in Beam Intensity.
Overall it is NOT that big of a difference,,,,,,,its not like you have a light that is 150Kcd and you are comparing it to a light that is 400Kcd.
