Update- blue light now is on!
Easy to replace the bulbs and it fits as it should. But I’m not sure if it’s working or not. I can hear the airflow but the blue light is not on anymore. If I reuse the original bulb the lights turn on but with this aftermarket one the blue light is dead…. I hope it still works even without the light?? We shall see… Update 10/30/25: seller reached out and helped me solved the issue. You have to securely screw the lightbulb tightly. If it’s a slight loose the blue light will not turn on. Make sure you install it tight and put the screw on correctly. Blue lights is on and it works perfectly!! A++ for the seller reaching out. Great customer service!!

Reasonable price for uv bulbs. Hopefully they are the proper spectrum to do some good.

Well packaged & works in UV-C sanitizer
Edit, Sept 2024: I purchased another box of 2 bulbs in June 2024. I finally got around to replacing the burnt out bulbs of 2 GermGuardian units in Sept. First 2 attempts - both bulbs didn't light up. I thought this was odd to happen on both bulbs on 2 units. Then I realized the bulbs were not fully installed. After finger-tight, wait a moment before gently twisting the bulb tighter. It will be about a quarter turn before the bulb threads give and allow another turn or so. Then, the bulbs both worked and lit up bright blue. I'm glad I didn't need to buy another set. Original, April 2024: Two pack light bulbs packaged carefully in a small box. They were easy replacements for 2 GermGuardian plug in models: GG1100 and GG1000. These can be shipped to CA. Will likely repurchase when I need more UV-C bulbs.

Didn’t Work & Neither Does Device
I took my time, was very careful, wore a new pair of nitrile gloves, and not only did Neither of the two bulbs work, just trying to change the bulb caused the plugin Germ Guardian device to break or somehow fail. It is also now past the return window, so that was a crazy expensive fail.
