According to my research, this is an extension for the base station https://www.digitec.ch/fr/s1/product/philips-hue-buratto-basis-wall-lamps-ceiling-lamps-6659436. If you don't have it, you can't use the extension. If you have it and need an extension, then it would be correct.

Hue Runner and the Hue Buratto spots have the GU10 as a replacement bulb, both coloured and white only fit. The bulb should not stick out and should be flush. The bulb supplied is the following: Philips Hue White Ambiance Extension (GU10, 250lm, 5.50W) These can be replaced if required.

hi, yes, that should be no problem. The part is not that heavy... Of course, no guarantee on my part ;-)
