This is an E17 bulb, (standard Edison/intermediate base), that gives warm light at around 60-65 watts. So it does not fit your inquiry for a 25 watt bulb
The overall bulb height is about 6 3/8 inches from the tip of the base to the top of the dome.
Flood light
They are around 6 3/4" long. They fit the standard cans perfectly.
These bulbs were purchased for 2700k temperature rather than cri, used as general lighting and colors were true to what we expected. More interested in energy usage and warm glow.
If the bulbs are on dimmer switches, they need LED compatible switches. Philips has them listed on their website.
Glass
yes, good for bathroom, especially with you have dimmers
