Cable for outdoor lamp too short

Remove the thermal insulation around the cable, about 10 cm deep, then strip the cable, put Wago connectors on it, attach a new cable piece (50 cm), reinsert and/or foam the thermal insulation.

If you do it well, everything will disappear behind the bracket of the lamp and nothing will be visible.

I would then put that in a small waterproof junction box. That way you should be on the safe side.

Electrician was here, chiseled the insulation a bit, put WAGO connectors on it, pushed the connectors into the insulation, extended the cables, everything hidden behind the lamp. Fits

The main thing is that he also sealed everything then. Not that later you have a short circuit because of water or worse, water gets into the insulation.

Then let's hope that no water can get in when it rains and that the lamp seals it sufficiently. But a professional is responsible for their work and will therefore know what they are doing.

I certainly hope so. What about old WDVS anchors in the insulation, they stay in, right? If they are screwed in properly, they don't harm the insulation...
