For all Steinel, Merten, and Gira, I find comments that the products do not last long and fail at low temperatures. With Steinel quite often, with Gira the least, but in total only a few comments can be found there.
However, I consider 70° illumination at Gira far too little when I want to illuminate a wide driveway. The max 5m function with Steinel would already be almost perfect for that. Therefore, I tend to Steinel and hope to get a good device.
Thank you for your tips.
