The reliability of the starter cutout of Philips SON 70W that made in China « on: August 11, 2017, 03:36:59 AM » Author: dor123
Until the last year, every Philips SON 70W that I've encountered that doing cycles, had their starter cutout closing after 4:30 average. In the recent times, I had three cases where Philips SON 70W that took ages to close their starter cutouts and restrike.
These case were:
1. A cycling lamp inside a globe lantern at the playground near my hostel, that took 8:20 mins to restrike while capturing it.
2. A lamp inside an AEG Minikoffer at a pavement between the streets Moshe Sharett and Ben-Zvi, that went out due to a small power dip and took 10:12 mins to restrike while capturing it.
3. A lamp inside a globe lantern at the playground near my hostel, that went out due to a small power dip and took ~7 mins to restrike while capturing it.
From the third case, where the lamp was completely visible (Globe was clear and without reflectors around the lamp), and where the event occured during trying to photographing it and its etch, I've reached conclusion, that all of the following three cases of very long hot restrike periods with Philips SON 70W, involved chinese made lamps, while all of the cases of Philips SON 70W restriking after 3-4:30 mins, involved Belgium made lamps, so I think it have to do with the crap reliability of the starter cutouts in the chinese lamps.

Are anyone others have also bad experience of chinese Philips internal ignitor HPS lamps taking ages to restrike?

The Philips in your country and the Philips that made the SON 70W are two different companies, so quality of the lamps may vary. I'm discovered that China made 70W internal ignitor HPS lamps of Philips lighting Europe for 220-240V 50hz chokes, that are made in China, takes forever to restrike, compared to the Belgium ones, that restrike after 4:30 mins average.

SON E/I lamps are not meant to be fast restriking. They are intended to be a cheap reliable lamp, and they do well on both accounts. For fast restriking use a SON T lamp

Another problem is that those Chinese made lamps won't last long in enclosed fixture. My friend uses some SON-H retrofits where the contacts of the glow throttle melts together over a few hours usage. Maybe it is the same problem there and wouldn't be that long in an opened fixture.

HID lamps aren't sensitive so much to working temperatures in enclosed and open fixtures, like CFLs and LED lamps do. Also, HPS lamps usually have vaccum filled outerbulbs to provide thermal isolation. So I think it is matter of luck that the starter of your SON-H in your open fixture survived longer than the one in your enclosed fixture. Here, most Chinese Philips SON 70W, begins to cycles before the starter get stuck. The only problem is their starter cutouts takes ages to close.
