Here's some stuff I typed up in reply to questions I received about #5, The Bruiser via PM:
Output of the Bruiser with the overdriven 50W bulb is definitely north of 2000 Lm. For lumen output specs on the Osram 64440 bulb in the Bruiser, or the Hikari JC-5033 which I can provide 2 or 3 of, along with other voltage-compatible bulbs, check out Lux Luthor's Destructive Incan Bulb tests thread.
When selecting bulbs to try in this light, keep in mind that battery voltage sags under load, but also that pack voltage when hot off the charger is way higher than a day later. The most practical way to select a bulb to go with your pack is to understand the sag at the target amperage, avoid pushing the bulb to within one row of the "flashed" row on Lux's charts, and rest your cells a day before trying out the combination.
For the battery sag under load, refer to SilverFox's NiMh Battery Shoot Out thread. I'm supplying 20 Titanium PowerMax 1800 with the Bruiser, selected for their very low sag.
A hotdriver could possibly be installed between the switch and the Kiu socket, but the fully assembled AW switch with post assembly could not be substituted for the existing switch, because the existing switch is integral to the "built-in battery carrier" construction necessary to fit 20AA in a 4D. It has been shortened and incorporates the four contacts that directly contact the four stacks of cells.
*Update to everything in this post*: Among the included cells, one or more must have increased internal resistance, as observed by output of various superbulbs and not popping several bulbs that surely should have popped, but did not (see post #1). I don't know how to identify which of the 20 cells are affected. If I am able to identify and replace the bad cells before the light is sold, I will. Otherwise, the light is sold as-is with the cells as they are, and the 20hr 50W 12V bulb installed, being overdriven to an unknown wattage. Other bulbs still included, as mentioned in the post #1.
