have my old 40W bulbs replaced it, and the effect is really amazing. The words "replacing 25W" is an understatement, they are much (!) Lighter than the 40W lights. The light color is slightly whiter, closer to the daylight spectrum, are indicated 2,900K (there is really no one else absurd that 3000K as "warm" and the double temperature are referred to as "cold"?). Compared to Osram R50 light is much less addressed and uniformly illuminated the entire space to creating focussed illumination therefore less suitable. All the plastic dome of the lamp is uniformly bright, individual LEDs are among unrecognizable. For me, a small downside is that the whole lamp including shaft and housing is completely white, looks in my black lights off not so great, but a star deduction does not justify that. Now I have only one problem, the tens pack is already empty, I'll probably equal to more order ...
