Yes, but this is too yellow, it is like underdriven incandescent...

I thought the same at first, but when I tried a the osram 825 cfl I changed my opinion. I like this color very much for ambient light.
BTW here in Europe it seem that Osram as switched their entire line of self ballasted cfl to 825 instead of 827.

"CRI of 85 is simply NO GOOD! I MUST have 90!"

Really?

I think they are trying to mimic their "RELAX" line of incandescents (yellowish filter coat), but for me this is simply too yellow (both RELAX incandescent as well as CFL). Interesting the CFL look like the yellow is not made by phosphor composition, but filtering tint - the lamp has same color tint when illuminated externally...

I think incandescent is around 2800K, even the 2700K CFLs are warmer than incandescent, let alone 2500K.

It depend, if you are using "230V" or "240V" rating for 230V mains.

Medved, I don't know, the voltage fluctuates here a lot, but I always found incandescents (at least higher wattages like 75W and more) produce whiter crisper light than 2700K CFLs, which are also a bit pink. 3000K fluorescent is fine, I haven't found those as pink.

Whether 2700K or 2500K is considered too yellow is a matter of taste. I have a "Scandinavian" taste for color temperature when it comes to indoor domestic lighting and I tend to like 2700K and less better than 3000K or 4000K lamps (I won't even mention the harsh 6500K lamps used for domestic lighting in the Middle East and Asia!). I consider most 2700K labeled CFLs still too cold; very often a slight unpleasant blue or green hue is present that is absent when using real incandescent lamps.

I use a 2500K Philips Mini White Son 50W lamp in an uplighter and I like the color very much. Same applies to fluorescent color 92 (=927) and old color 27 that I use for illuminating the kitchen, bathroom and bedroom. All these lamps are NOS, they can't be bought anymore in the stores.

I think that color 92,927 (Philips) and 42 (Osram) have been discontinued due to very low demand. Also, efficacy is less (60lm/W) compared to 827 color (80lm/W) so you will need a higher wattage to obtain a certain amount of lumens.

Also, efficacy is less (60lm/W) compared to 827 color (80lm/W) so you will need a higher wattage to obtain a certain amount of lumens.

It is, as for this you need to emit significant energy in deep red area, where the eye sensitivity is very low, so the energy spent for them does not bring lumens...
