Maxabeam: how many lumens

[FRITZHID]

Yeah, gotta agree with Ma, that's got to be a Gen2 from that date. You can get new genuine Peakbeam Gen3 bulbs on Ebay from a particular seller for about $100 IIRC plus shipping. He's got a bunch. Search for Maxabeam bulbs. Just a note that even though they are Gen3 bulbs, there is a newer bulb being used by Peakbeam now. The big difference is going from the stick bulb with tubular arc chamber to a round arc chamber. Significant difference in the beam.

thats an understatement!

What's the difference? Beamshots??

A tubular arc chamber will diffract the image of the arc to varying degrees depending on the viewing angle. Since the reflector takes a range of viewing angles, the thing it is trying to image will see varying degrees of refraction at different angles, leading to a less well focused beam. Think kind of how if you look at an object through a piece of glass at a sharp angle, the object appears to have changed in its location in space.

A round chamber minimizes this effect, since at any angle within the lamp's viewing angle the light is hitting the surface of the round chamber at a normal of ~90 degrees. Kind of like how if you look straight through a piece of glass at an object on the other side, the object will appear to be where it actually is.
