Administrators, feel free to take this down or move it if it breaches forum rules.

Wrong ballast , crappy wiring job , heat from the lamp will eventually melt the PVC pipe , An ignitor is NOT called a "sparker" !!

I kinda see what he tried to do, just it wasn’t executed the right way.
 

Well that's 9 minutes and 21 seconds of my life I'll never get back 

This springs to mind...




 

LOL!   

@ Sammi : I believe it's called natural selection !!

The most sketchy thing has to be the soldered leads on the lamp base and the PVC pipe base.  A proper mogul socket is only a few bucks online.

I'm surprised that the lamp dosen't cycle too. He's using a 100w ballast which is designed for a 55v lamp while the lamp looks to be a 250w which has a 100v arctube. Perhaps it's underdriven so much that it never really warms up and hence won't cycle on a 55v ballast. The underdriving is probably the reason why it has a LPS look to it too. It's not truly monochoromatic like a LPS since there are faint emissions from other elements in the arc tube like xenon and mercury that a true LPS lamp won't have.

The ballast is a Sylvania 100w M90 PSMH .

Ok that explains the lack of cycling then.

The lamp would probably last forever that way.
