I assume that these lamp with me in the workshop, about 20 sqm large room where I like to have light when I'm working in it. For this lamp is perfect. Through its 4-stage brightness setting you can adjust the brightness. And when they were even in the brightest stage consumes only 20 watts, I run them at this stage. It replaces 2 fluorescent lamps, which I had previously installed and compares favorably afraid not absolute. On the contrary, the light is better than before. This is supported by the neutral white color of light, I would not use such a lamp in living rooms, but there where it depends on high light output (cellar, workshop, loft, corridors or other), this lamp at home. The installation of the lamp is not easier or more difficult than with other lamps, 6 dowels, screws and spacers for the event takes place that the lead surface mount are included, the lamp is simply screwed, the cable connected to the existing terminal strips, set the desired brightness level, finished. Since my blankets all are white - just like this lamp - they do not carry on, it falls when switched off barely on. It is thus not a "design element", but that they should not be, because in the above areas that would be more of an inconvenience. Due to the low height of just 10 cm, it can also be used in rooms with low ceilings, without one would stumble on hanging lighting devices. Conclusion: Highly Recommended in areas such as the basement, garage or in hallways! I am considering the purchase of the sensor light for my corridors.
