This LED G25 bulb is manufactured in China
Hi Derek - you have it correct, the soft white version is being replaced with the warm glow version.
They should if the originals were this style. Ultimately depends on the diameter of the globe.
5000K is the light color, not the light intensity in lumens output. I am not sure of the output.
No, there is no writing on the top of the bulb. I use these bulbs on a vanity light bar.
Yes, there is no lettering on the bulb itself.
