Philips EcoVantage Clear 72 Watts

Here I picked this up from Home Cheapo on one Saturday (2011-11-19). They are essentially the overgrown Christmas light capsule as the classic Halogen√° BT-15 bulbs with classic A19 shaped bulb but with the reduced wattage.

The packaging looks very similar to my 240v 70w version, see here . Shame yours is only rated at 1000 hours but then again I've had many of these (in other brands like Osram) that are supposedly rated at 2000 hours, last not even 500 hours.

Traffic signals & street lighting engineer. Please bring SOX/LPS back Downunder!!

I think they are slightly overdriven the filament to make the 'halogen' effect and that could contribute the lower life rating. I don't even think this one has the halogen compound in this capsule

Pretty, please no more Chinese failure.

@rjluna2: The 1000 rating would not be possible with the 1490lm/72W without the the aid of halogens. And such small capsule would become heavily stained pretty quickly...

Now, here is the question, Medved, can the glass capsule withstand the halogen compound destruction that the quartz can stand?

Pretty, please no more Chinese failure.

What you mean by "halogen compound destruction"?
The only reason for the use of quartz in halogen incandescents is the operating temperature of the bulb. Some time ago appeared halogen capsules using a bit modified fill, so their operating pressure, so bulb glass temperature was so low, so it allowed their manufacture from hard glass instead of quartz.
That allow cheaper assembly and (according to some promotional videos) lower convection losses.

@Mevded: It is my understanding that the current halogen compound is usually Bromine to have the halogen cycle to reduce the emission from Tungsten filament when it is burning.

Pretty, please no more Chinese failure.

Yes, bromine and iodine are generally used for that same purpose. But that have nothing to do with the bulb material, both glass and quartz are inert towards both of these halogens.

Bromine is used in the low pressure designs, where the bulb operating temperature is lower, so allow the use of cheaper hard glass. based on how seals are made on this (^^) lamp, it is this type (it use seals directly around the round wires, without the use of intermediate molybdenum foil necessary for quartz).

Do these explode at EOL ?

NNNN!

Based on manufacturer's claims not, because of the low pressure.

But my experience with mains halogen capsules is, then they do explode, about in the same way as standard incandescents - so do not mechanically damage the fixture cover, but send shower of glowing hot and sharp parts...

So you would not make any mistake when treating and using them like they would explode...

@Medved: Thanks for the clarification

@Powell: the Tungsten filament is pinched at the capsule as a fuse preventing arc flashover.

Pretty, please no more Chinese failure.
