I use these for a golden glow.
The 25 watt that you are looking for seem to only come in daylight, not soft white.
Note - not all dimable LEDs are compatible with all legacy dimmers.
This looks more like what you are looking for, however. I haven’t used these in years, but I recall that the ones I got decades ago seemed to work with a dimmer, although they give off so little light, you’ll generally keep the rheostat turned all the way up.
Here’s the link I left off my post above
