I know that it can hot restrike without an ignitor, but I didn't know that in some extreme cases, it can also cold strike without an ignitor (As this isn't a probe-start MH lamp). I've seen this lamp restriking with a 750V two wires ignitor in one of L_V videos: 2 mins of cooling down only, and without any glow before the hot restrike.

Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I hope that LED won't replace all forms of other light

That could explain why this Metal Halide at EOL could produced similar colour as this

Pretty, please no more Chinese failure.

Rjluna2: In your case, the lamp leaked, and either the phosphor or the sodium halide, causes the lamp to exhibit this color. American probe-start MH lamps, don't have a neon-argon penning like this lamp.
