If you want to use 2 x Li-Ion tha telliminates the KL4, my first choice for "flood"
Aleph heads would need a LE with a DownBoy (DB) driver for 2 x Li-Ion, which is a very good choice with a 2-stage switch as there is no flickering.
Now the choice of the head for beam pattern ... I'll just show the alternatives:
Here is a comparison of the 20mm, 27mm and 38mm Aleph heads vs a IMS17 reflector with a LuxIII ...
... where you see that the 27mm Aleph1 gives a huge corona which is relatively dim and has a needle-like spot with a very good throw. A classic that is comparable to the beam of a Gladius, LH, Pelican M6, ...
The Aleph2 has the same beam as the McLuxIII-PD with a big spot that blends smoothly in the corona. The corona is tight and bright and much more useful than the Aleph1's corona, but it is smaller in diameter.
I guess the 38mm Aleph3 is too big for your taste.
Something special is the Aleph19 head ... which gives an almost pure concentrated flood with only the hint of a hotspot:
Here it is plotted vs a McR-20 (Aleph2):
Overall ... the Aleph2 (20mm) is the best compromise, but your needs might be different.
Here are the heads pictured:
The big Aleph3 throw king head :devil:
