I offer a Light monkey (formerly Salvo) lamp 21 W LED; 5.2 Ah. The lamp has always served me well, especially when diving caves. It has a very good spot of 6°. The mileage is 2.5 hours. The lamp is ten years old, the LiPo battery was changed once.
I'm selling them because I've been switching to a non-wired hand lamp for several years.
As a price I imagine 230 EUR VB.
