By any chance you were able to see the glow light starter? If so, can you tell what kind of gas it was used?

There is a purple glow,would that be xenon? There is only a glow around the outside of the bottom of the mini starter bulb which arcs over to the wire support near the stem, only when lamp is energized hot until re-strike.There is no glow observed when lamp is started cold.

My guess it would be argon filled glow bottle.

this acts as a voltage buffer, this absorbs the High Pulse Voltage generated from the Ignitor from the arctube until it cools down sufficiently to restrike.

That makes sense,thanks for the info Colin!

Hi Darren,

I think it is to reduce the stress on the arc tube which could explode suddenly with high voltages striking the hot gasses, within the arc tube

Out of interest I have the Same Lamp see HERE

All the Best

Colin
