Hi,
I am an Govt. engineer, and philips
was (not is) our first choice. But in India, after taken over by signify, the quality was drastically going down. The 20 watt slim recessed lights installed in the very important seminar halls, meeting rooms, and in youth hostels are get blinked when any switching in the ceiling fan or even regulator function happens.
While going through the driver circuit, I found absence of several parts in PCB. In this case, the filtering large capacitor, just after the rectifier, is absent, don't know, why, (causing reset of IC due to micro power surge)? Several times I found common mode chokes are replaced with single side drum inductor. Many times, the biasing resistances and electrolytic capacitors remain absent, reducing the life of the entire luminaire drastically.
In retrofit T8 lamps, the two series resistance used in series of line & neutral, are of low wattage, and fails mostly. And in street light and high wattage lights, surge units are mostly compromised. I can send you the pictures of the failures, in lot, it's reason, reverse engineered. Later, insted of replacing a lot of fittings, we have to install separate surge unit, to use those fittings.
An interesting fault was found that due to replacement of rubber gasket, with plastic gasket. The metal body enlarged in heat, but the optics are get cracked, as it was get stress, due to absence of rubber cushion in between screw and optics hole.
In India at present, general publics are not want to pay more for philips, while they get failure even quicker than their local brand. Even us, the govt. officials, having the maximum inertia of thinking (As we cannot experiment more with public money), are changing.
Sometime some rumers came in ear that great quantity was manufactured in india by it's dealers in their private workshop, to cope up with high surge of demand before Puja and March year ending. Surprisingly after inspection, when query is done from govt. officials or it's vendor, philips signify says it's their product, and then repair or replace later. I have the official documents, but cannot upload here without permission.
If this is the quality of the our old beloved philips, sorry to say, PHILIPS dying...
If you really want to know the differance of your design, and what we get in reality, you should purchase philipsproduct, from that country's store (may be online store), and test the differance.
An visit to youth hostel in purulia, west bengal, I captured the video of blinking of philips light, with ceiling fan regulator changing.
Here is the link. The language is in local language bengali, however, you will realise, the current status of your reputed brand in INDIA.
