Why is the TKB TZ67 Dimmer Socket no longer a certified device?
In the past week or so a few customers reported a couple of issues with the TKB TZ67 Dimmer Socket and upon further investigation and testing we confirmed that those issues exist as follows:
The following additional tests worked correctly:
All tests were carried out with a variety of bulbs - LEDs, eco-Halogen and Incandescent of different wattages.
Vesternet believe that the issue with the locking up of the device is caused by an extreme set of circumstances and we don't really see how the locking up would occur under normal use. The TKB TZ67 Dimmer Socket has been on sale for a long time now, we ourselves have sold 1000's of them so the total sales worldwide must be many, many times that amount and this is the first time we've heard this problem reported.
The soft-on / soft-off issue is a strange one as it's not 100% clear what the correct behaviour should be - there are other dimmer sockets that have soft-on / soft-off working consistently, but there are some that don't do either soft-on or soft-off. An example is the Popp Dimmer Socket - this does soft-off (and is also configurable for the delay time to turn off) but doesn't do soft-on at all.
It's therefore our opinion that these issues do not detract from the fact that the TKB TZ67 Dimmer Socket is a great product at a great price!
