I have a BD04 I use a lot indoors. It is single 18650 battery with on-board charging capability. Has been modded with a 4 additional 7135 current regulators, jumpered the MCU to remove the strobes and a warmer tint LED. It is my go-to light inside the house. Zoomed in it is all flood.
Other zoomie lights are out there but the BD04 is the only good quality one I have.
Sipik SK68 is another cheap zoomie light that uses AA or 14500 LiIon.
Not a big fan of the zoomie design outdoors because if its wet, the vacuum created sliding the bezel will suck in water.
I am sure many other suggestions will come up.
What battery form factor would you be using?
