The cone of light is very large, so about 60% of the visual field and also nice and bright. But I doubt that the 80 lux. Have previously a 40 Lux lamp used, which was not bad. But for such a small and light bulb, the light intensity is good. The Single ADJ END bzw.Wahlschalter other hand, is very sensitive. Keeps hopefully as long as the LEDs. Installation was easy, was even able to use the old bracket, and existing cable. I can recommend the spotlight. But a more favorable light, it does too!
