The LED bulb replaced ESL with 9 Watt. Specifying the brightness seems too optimistic. Lamp is very compact and could therefore be 30mm well installed with max diameter lampshade (opal). Light color is warm white similar to the color of ESL. The design of the lamp is solid, but you should not interfere with the light image (corn shape), because even in the milk-glass lamp shade, the individual contour of the individual LED lamps can be seen. From the light output compared to the ESL I am not entirely convinced, but the price-performance ratio, although the energy efficiency watt / lumen appears not quite understand me.
