Philips 1000w HPI-T Pro: Full Power.
A nice shot of the arcstream of this nice big 1kW metal halide lamp.
Observing lamps like this is just awesome...
Almost all of the halide dose is evaporated except a small amount under each electrode.

Lamp is god damned bright!

It is strange that the indium, the thallium, are all evaporated, even if the HPI-T have a very fast run-up, because in my now destroyed Venture MH-DE 70W/UVS/GDX thallium lamp, there is a pool of liquid thallium at the bottom of the arctube when hot.
