Maybe factory error or overloaded by ballast.

Probably the lamp was already jammed and the heat eventually resulted in that.

There is nothing to worry about here, your fixtures and ballasts are fine!

This can happen to any lamp from any brand. It is caused by the glass that holds the filament structure being improperly cured during manufacture. The glass is stressed out by defect and the heat from normal operation causes the stress in the glass to fail at random. When the stress gives way, air suddenly rushes in and takes away some of the coating along with it, which is why the lamp is clear there.

Sometimes, the stresses in the glass base don't cause instant failure, but instead a slow air leak will result. The lamp will still work at first but the lamp will start having issues starting, may change colour and brightness and eventually stop working altogether. If the leak is slow enough the lamp can still work if left on most of the time to burn off the air contamination



This can also happen to incandescent lamps and HID, although with HID , it is only the outer bulb that loses vacuum so it will still produce light but it will have some problems with brightness and colour without the proper thermal operation from having a vacuum.

I hope this explanation has helped you. Cheers!

I do agree with Lightingguy's comment. Also the fact that the phosphor coating has been blown off is a clear sign that air entered the lamp very rapidly, which would point to a sudden cracking of the glass.

I once had that happen after operating a vintage NOS GE F30T12/GREEN for the first time. A more common problem were the GE Powergroove 1500ma lamps leaking after being operated for a time then cooled down, although not dramatic...just a slow leakage, possibly hairline cracks around the grooves.

Thankt for explanations! The replaced tube is still running, so, it was an incident what happened in my eyes as the first time for Philips
