Snap, crackle and POP...and shatter....

Snap, crackle and POP...and shatter....

Click to view full size image

I spotted this Sylvania Urban today while out and about. Something has occurred here and as a result the 80watt MV lamp has shattered. I drove past this tonight and the arc tube still works and emits a lovely 'clear MV' glow. I have seen several Urbans in this state over the last couple of years, and all have been on steel poles. This Urban is mounted on a steel pole exactly the same as this one here - the pole in the link is not the same pole or area that the Urban from this photo is located.

I'm a little disappointed at the quality of this photo - I seem to be shaking a lot more lately when taking photos which makes photos blurry. I was taking photos of the demolition of a an abandoned meat works last weekend and was able to use a fence post as a tri-pod lol - what a difference having a 'tri-pod' makes! I'd love to use my 'tri-pod' for my street light photos, but it's a little difficult when one has to stand in the middle of the road, next thing you know the Police will be there and I've been in enough trouble with them recently because of this hobby!

Here is an 'up close' of one of my Urban's.

I didn't expected that the outer envelope on MV bulb could shattered leaving the arc tube intact

Pretty, please no more Chinese failure.

Perhaps poorly annealed outer envelope?

Annealing (glass)

Pretty, please no more Chinese failure.

Can you see much fluorescence from the fragments/phosphor? I suppose the air gap and the glare from the arc-tube may make this hard to see.

I have a mono-pod for when I'm out and about, easy to carry around (lightweight and fits in my back-pack) and gives good stability. Also makes a quick escape easier

Hi James

Ihave seen a couple of instances where the smaller MV lamps have shattered with the arc tube remaining intact. In one case the lamp was inundated with water - fair enough. Not sure what causes it in a lantern like this other than mechanical shock to the pole. Being an 80W the bulb is very fat in an Aeroscreen Urban - too close to the cold glass maybe?
