The 4 watt Philips seem to me subjectively to be between 30 and 40 watts a bulb. If you nachmisst that is not true, I suspect this is due to the slightly whiter color.
For me, an acceptable compromise, if you have to do without the light bulb, for kitchen, bathroom and dining room. For the living room and bedroom in the evening I needed a warmer hue.
Really liked me shape, uniform illumination and viewing angle.
