The lamp inside.
Here is the lamp inside the Form 109. Is that... Metal Halide?? I looked closely and it looked like it had a metal halide lamp in it.

No that's definetly mercury vapor. MH arc tubes are much shorter. The white on the ends is probably becuase this is either a LifeGuard or Bonusline lamp.

Form 400 has the same glass design as the Original M-400 up to the M-400 R2, And the glass design has gone through several minor changes, like deepness of the refractor.

Yep it is indeed a MV lamp. Ian I suggest you start studying lamps more now to learn more about lamps. Put your streetlight "obsession" (hey we all have our obsessions, so do I!) aside, and start expanding interests that is linked to streetlighting, such as lightbulbs and photocells!!!!!!!!!!

I would save it if possible, that 400w BT lamp looks pretty cool.
