Due to the change in the efficiency classes a few years ago, both details are often still displayed:
Energy efficiency class until 2020: A+
Energy efficiency class from 2021: G
The 1s and 2s have the addition "BT" (for Bluetooth). This means that they can also be operated without a Hue Bridge. The wattages are probably identical for both versions. Depending on the version, the lamp was measured and specified at 100% or 80% dimming.
The description is nevertheless accurate and complete.
- bridge (bridge for wifi connection)
- network cable
- 3 light bulbs
- a dimmer (button)
- power adapter
The statement that there are both with and without BT refers to the lamps - in this product the 3 spots - and they are BT-compatible. However, the Hue Bridge needs to be connected to the network via Ethernet. If you then have the bridge in operation, the lamps are no longer controlled via BT but via Wifi. Without the bridge, you can (as I understand it) control the lamps directly via BT.
Yes, it would even be advisable to remove the dimmer and install a normal switch.
Depending on how exactly the Hue lamps are to be used, they must have power all the time, even when they are off. The control system is located in the lamps/lamps themselves.
I think not. I have the product and could not find any reference to bluetooth. I think the Hue products with BT have a small blue BT icon on the box (see Hue Lightstrips).
