The brightness of the lamp is very borderline. Only by adjusting the lamp reaches the optimum brightness depending on the situation. The adjusting and fastening the lamp are very good. Personally, I find the also for 38, 57 instead of the previous, quite expensive. But you can also expect more light. Nevertheless, it is the old halogen bulb replaced in the long run because they simply consume much less power and the lamp can be adjusted as needed. For optimum light efficiency maybe even 2 lamps would be recommended, but this would be too expensive.
