What I as absolute impudence feel is the effective power of the bulb. My power meter shows 44 W to. What should the print with the 150 W I do not know. Perhaps the maximum recording or the peak power. On average, therefore, the effective power, unfortunately, only 44 W.
The light intensity is quite comparable to a standard photolamp with 55 W. The lamps I've bought because I thought that I would get much brighter bulbs. This is a total letdown. Saves you the money people, the here is no different to conventional lamps, which are already present in lampshades.
