The Nernst Lamp

Nernst.JPG Intrigued by Gav's picture of a Nernst lamp on the gallery, I was keen to find out how they worked. Having looked around online, this is what I can find: The Nernst lamp (also known as an incandescent "glower" lamp) uses a small ceramic rod, heated to incandescence, to provide ...

It's very much like the technique they use for putting fish farts in spirit levels. Collecting them first is the trickiest bit.. like the whisps of smoke! :rofl :rofl

Short Time Running Of Fluorescents

Is there any detriment to the lamp if it is run for a relatively short period, say 20-30 mins at a time? If a lamp hasn't been fired up in a while, should it be considerably longer, a bit like some discharge lamps?

Re: Questions: SRS instant start and tube banding

Indeed Slyspark... the teardrops usually appear at the ends of the cathodes, near the supports. As these are enclosed by the shield, that effect is eliminated. It's almost like a hotspot is created at the point where the cathode meets the support and this slowly burns away the phosphor. The shield f...

Re: Questions: SRS instant start and tube banding

Is the cap the correct rating for the circuit? I imagine that would have an effect on the starting... I have noticed that on my SRS fittings, new tubes usually start instantly like they do on SS and tend to only do the classic SRS start up when warmed up. Is it because the lamp is warm or because th...

Hahaha! That's hilarious!
Thing is, when did the flood of cheap rubbish start coming in from China?
