The Betty costs almost $900!
Newbie - exactly as you said, definitely a price for the insane, lol! Or the insanely rich!
And on that same subject, tonkem, did you sell your older Betty and get a new updated one? Does the beam throw reasonably well? From the beamshots posted on the Lupine site, the new Betty, although still a flood light, appears to have a more 'appropriate' beam with more throw than the MM15 - which has way too much flood and no throw, all because they wanted to make the light shorter and smaller. Shorter and smaller is good, but not if it sacrifices usability.
Also, imho I don't think there will be another Zebralight S6330-type light, regardless of whatever their sales rep may say about it. Their product chart consists of only small single battery-type lights. This shows that their general business philosophy is not large multi-emitter lights. Also, the S6330 probably requires a chunk of expensive hi-quality aluminum 6-8 times the mass of their smaller lights. Its nothing but a huge chunk of metal that has been hollowed out, turning most of it into metal chips for the scrap heap. Not to mention the cost of shipping heavy things around the world to and fro. Also, with the S6330 using 3 times the number of LEDs with a separate driver for each LED but at a price point only twice ($200) as much as their single LED lights ($100), plus their attempts to move manufacturing to the US - which means even less profit per light - all tells me the S6330 is not a big money-maker for them and with a worldwide stale economy, there's no incentive in this direction.
The only reason I can think of as to why any company would keep building a coke-can sized multi-emitter light is that their smaller lights probably aren't producing enough of a profit and aren't selling as well as Zebralights.
Here's a design idea: Have two 18650 batts sitting parallel to each other in a round tube like the Lupine. This leaves some unused space 90 degrees apart in the tube at the head where the base of each reflector can take up about 1/2 inch depth in that unused space, thus overlapping with the batteries. In other words, the base of the reflectors overlaps with the batteries about 1/2 inch - this allows for deeper reflectors but scrunches the reflectors and batts together at the head-end to keep the overall flashlight length as short as possible.
