After two disappointing with special clamp lights, I came to the Atlantic mouth. For the low and reasonable price, the quality is quite good. Especially positive I rate the included table clamp. It is made of metal! This has increased from 3 to 4 stars my rating. The plastic parts in the previously purchased lights was totally unsuitable as shaky, so these lights also went back. The other components of foot Atlantic light are good. The light starts after switching delay and without flickering. The color temperature of daylight lamp is very suitable for the intended use at a workplace. An observed with other lights hum is not heard. Good quality at a reasonable price.
