Induction fluorscent highbays in Stop Market Yagur Supermarket (Kibbutz Yagur, Israel).
Well, what you see!!! First time I've seeing induction lighting in Israel!!!!!

First time I see induction fluorescent lighting in Israel!

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.

I'm sure that these will fail very quickly as you believe that Induction lighting is unreliable.

The ballast is the only thing in induction lighting that is most likely to fail permanently, as it operates at several MHz and so it is more complicated than LED drivers and fluorescent electronic ballasts.
The lamp have almost no things to wear, beside phosphor degradation (Which is not so likely to be happen as fast as in T5s and CFLs, as the tube is much thicker, so the loading on it is lower and the heat is also lower in this configuration), and mercury starvation (Which I've yet to hear this happening in induction fluorescent lamps).

Please provide evidence that Induction ballasts are likely to fail prematurely (you wrote permanently but I think you mean prematurely).

The producers of Induction lighting advertise the longevity of this particular lighting technology, therefore it's a serious issue if they have inherent faults such as the ballasts failing prematurely. I'm sure they'd take your findings very seriously, from a financial & litigation point of view.

Al_M: Read what Ash commented in this thread , when I mentioned the induction lighting as a more reliable alternative to LED lighting, while including this picture.

He says exactly the same as you, and he also states no evidence to back up his claims. Ash doesn't know everything like you seem to think he does.

Dor compares the best class on the market induction lamps to the common cheaply made or retrofit purpose LED products

When you compare the best induction like QL, please be fair and compare them to the best class LED and not to some "domestic user reliability grade" LED device which are what Dor is the most familiar with

Re reading my comment i realised that you might have understood it the wrong way around, so here it is clearly for best understanding : i am claiming that "the best LED can work for 100K hours + and have less problems than induction". Apparently you and Dor read it as "the induction lamp is even less reliable than the crap LED that does not last its rated lifetime"

In both the best induction vs best LED the greatest concern is the driver circuit and assemly. the LED's circuit is simpler, and he LED's assembly procedure does not involve assembling a tightly packed coil connected to a fragile glass object. Therefore the LED have less places where something can go wrong in other words. more reliable

Ash: I don't comparing the induction lamps only to the LED retrofit lamps, but mainly to the LED fixtures in commercial and public places which should be the best class LED things, and I've seen both in LG and in my life, many commercial LED fixtures that failed prematurely. These external coil based induction lamps in this picture, belongs to some of the lower quality generic ones, based on their circular shape (Higher class lamps of that type, should have a square shape similar to the Osram Endura). Also, I'm yet to see a mercury starved induction lamp in LG.
Indeed, I wonder how long this system will be last (But I bet that phosphor shouldn't be an issue, as their brilliance was far lower than that of the T5 standard output, and they weren't glaring either, meaning lower loading so lower temperature than T5s as well).
And I already stated that induction lamps of this type, usually have the same efficiency as triphosphors fluorescent lamps of all types except energy saving CFLs and TCs with multi-tubes (TC-T especially) which have lower efficiency, and MH lamps. And they have also the same CRI (Ra8=85) and colour of all types of triphosphors fluorescent lamps. So they aren't a choice of energy saving concerns (And they are indeed not suitable for floodlighting).

Many of the LED devices in commercial places are not made well enough. The owners of such places often go for the cheapest option available when they do their "efficiency upgrades" because even the cheapest LED products have the same 100K hours statement on the package. It should not be like that but it is....

High grade LED products dont have abnormal rate of early failures. Those can be found in commercial places but only sometimes, because the number of owners or electricians who care for quality is fairly low
