This isn't crap I have one predecessor to this made in Italy...and it works very well. Now the new Osram PowerTronic are from China...I din't buy those cause they look like crap...and cost the same as the Italy ones .

At least you have a choice to use magnetic..save alot of money. I have to use electronic because my supply voltage has problems...too low and damages the lamps. This Osram Powertronic tries to maintain lamp power versus input voltage and I can 'see' it do that with some very slight variation in brightness when running the lamp.

What so you have voltage flutter where you are?

Apparently so as it cannot be detected by a DMM. It shows 235v in my bedroom and 238v in the living room. I tried using a variac to increase the voltage to 242v with very slight difference. I know it's low because the arctubes start with much sputtering and turns the arctube abit brownish/greyish. An MV on my supply won't last more than a few months before loosing all of it's electrode material.

Off topic but the PCB in this looks almost identical to the philips EBs for MH i have!

@kevxsi16v: The incandescent bulb in our bathrooms dip in brightness quite a bit from time to time like suddenly I'd notice it get dimmer abit but it's not obvious in flourescent lighting. I suspect it's the crappy wiring that service the flat building it's 3 phase but each phase serves 4 floors and each floor has like 10 units. It should be 3 phase per floor so each flat unit will get one phase of the 3 phases.

The lamp is made by GE CMH supermini 35W/930 Base G6,5. I also think this electronic ballast it is not crap, I know places where they are working in large population, perfectly since years.

Old post, but have to add: I know many shops around here which use these for their spotlighting. Installatios have built about 10 years since with these ballasts inside. They work perfectly well today, only few has failed due thunderstrike past summer. I can agree that quality of these osram electronics is very HIGH.

Have to add some more: Most serious thing to degrade the electronics is the heat. There is arrhenius rule calculation that 10'c lower temperature doubles the life. Good quality rail-spot fixtures are designed by knowing this. When electronics is kept cool enough they can last very long. This is most important failure reason for many fixtures using electronic ballasts. Keep these cool and use they over decades.

I've had good and bad depending on brand. The Philips seem to come in batches sometimes they are good and like you I've had them do over a decade but in other places dead within 2 years. The tridonic multi watt are terrible lamp goes black and the ballast goes bang.

I've a Philips Primavision ballast for 70W CDM in my indoor floodlight that made in China. I hope that it will last long. It isn't integrated in the floodlight itself, but in a seperate ballast box, as it is on a track, so the floodlight and the lamp don't heats it.
During hot restrike, most electronic ballast don't ignites the lamp constantly but trys for a brief and wait several secs. My ballast however trys continuously like a regular superimposed ignitor. I don't know after how many EOL cycles it shuts down.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

kev: yes tridonic ones, even the pci-c multiwatt types did not detect end of life modes other than cyclign. So erratic behavior that occur can ovedrive electronics.. Osram pti give up instantly when defective lamp is in circuit. They measure lamp voltage, waveform, ignition behavior constantly during use. Erratic behaviour -> stop.the system..

I have tested this. I put the defective (leaked)sdw-tg lamp to circuit and see what's happen. Tridonic ignites the lamp and outerbulb discharge is the result continues long... Osram ignites too but stop operation less than second..

There are several modes of failure: Cycling, rectification and trouble ignition. If the lamp can't start, the ballast shut down
immediately. If the lamp rectify, the ballast also shut down to protect itself. In the case of cycling, the ballast needs to do several cycles to distinguish between a cycle and a power outage that cause the lamp to extingush. The ignitors in the Schreder Sepale at Qiryat Ata, giving up after one cycle, and if the ignitor manages to save the discharge from extinction (Resulting in dimming/flickering), it knows that the lamp wants to cycle and gives up immediately after it losing the control on the arc and it extingushed.

Philips primavision is also good on this, but ensure that metal bottomplate is directly on the thermal contact to luminaire body.

Dor123... I know everything about these and is the result i can say.. the electronic can be good and bad but making a decicion need some experience with these units used long enough in professional environment. Shops etc. to make the statement.

Temperature in most important and detection of operating difficulties eg EOL. to determinate the quality of the design, and i can see Osram is high on this.
