Otherwise, the LED bulb works.
Luminosity 500Lumen but extremely optimistic. That would be a ca.50Watt bulb. (Rule of thumb: Lumen / 10 = wattage bulb in).
Here it replaces a 25W bulb and is not brighter than before.
The light color I personally find cold, but is ok because 3000Kelvin lt. Norm nor end of "warm white" are defined in the "cold". Anyone looking for something in the color of its light bulb takes 2700k better.
