Temperature sensitive outdoor light chain?
(OP)
Hello,
The company I work for sold a lot of outdoor lightchains to Europe for the Christmas season. We bought them in China and when we tested them they were fine. Now in Europe a lot of them flicker. They tell me it is because of the temperature.
In Southern China (+25 degrees Celsius) it is a lot warmer than in Northern Europe (less than 10 degrees Celsius).
Can this be? Are the lights or the adapter temperature sensitive? If so, we are in deep doo doo...
cheers,
GM

I've noticed that many electrical devices are of much shoddier quality these days. My paper shredder went fubar the other day and it turned out that a power connection was designed to be less than 0.050" from the metal chassis of the shredder, ugh.
Do you have any left that you can test at low temps?

For me thats have correct sense, the temperature on which are operating the blinking ligths.
As may be you know, those lamp chains are in series connection with a bi-metalic switch that open and close according the temperature self-generated for the current pass in this device.
If this kind of thermostat cools very quickly of course the ligths will appear as blinking too fast.
A possible solution can be locate the switch on the chain , and cover with many turns of isolation tape or masking tape in order to delay the action of the switch.
Good luck.

Thanks for the thoughts...
>> mvcjr - As for the difference in frequency, I dunno, we've never had problems with that before. But I will look into that as well.
>> cbarn24050 - We sample check, but the amount of problems we're facing in Europe is not proportional to the amount we've checked in China. As for letting the Chinese shovel the doo doo, they are getting smarter too and start having labour laws...
>> melone - As for cargo, it was shipped by sea...
>> Jorge - I'll check out the bi-metallic switch.
