Three of these LED lamps replace three warm white 23W-Philips energy-saving lamps in my outer office light (flat ceiling light with frosted glass as a diffuser). The reason for the exchange were firstly the energy savings (which does not, however, too large - the LEDs amortize probably never), on the other hand - and this is the main reason - that the energy saving lamps have started very dim to light up and after about two minutes produced acceptable light. Especially when you come home at night has always bothered me. In addition, the energy saving lamps have over the last 5 years at least felt already lost some of their original brightness.
Now to the important things: the luminosity and color of the light corresponding to no noticeable differences to the previous energy-saving lamps (the 130W should correspond bulbs). As the energy-saving lamps, however, are several years old, they will probably have been clairvoyant as 100W bulbs). Only the beautiful difference: the LEDs from the first second on with full brightness and give the room not dim feeling as the previous-ESLs.
Watching one must, however, that the lamps fit into the provided bulbs. They are larger than a 100W light bulb. That was when I tried no problem.
