Questions about Philips Hue White Luster BT

Hii This only works with the lamps that have Bluetooth. Unfortunately, this one doesn't have it :/ E.g.: Philips Hue White Luster BT (E14, 5.70 W)

Look here: https://www.energie-experten.ch/de/wohnen/detail/neue-energieetikette-2021-in-der-schweiz.html "Features of the new energy label 2021 The familiar rainbow colours of the efficiency classes from green (best class) to red (worst class) will remain. The seven levels of the energy efficiency class scale are designated with the letters A to G. The classes A+ and A++ as well as A+++ disappear. The requirements for all energy efficiency classes have become stricter. A good appliance that previously carried an A++ label now belongs in the new class B or C. It has not become worse because of this. The efficiency classes have been defined in such a way that there will not yet be any appliances in the best class A when the new energy label is introduced. This leaves room for future, even better appliances. However, it is foreseeable that the first appliances will already be able to achieve the A classification today (e.g. washing machines and refrigerators). The calculation method, the guidelines for the declaration and the measurement methods have been adapted. A comparison or direct conversion between the old and the new energy label is therefore not possible. "

The data transmission only works when the lamp is switched on and it is only unidirectional ;-)

No, unfortunately not.

Yes, you can.

Unfortunately, we do not have any information on this at the moment. I'm very sorry.

So I took a quick measurement. According to me, it is approx. 8 cm from the thread to the head end.
