Replaced Humidifier Bulb- works great.
My humidifier bulb burned out and displayed an orange indicator on the top (instead of green). Popped one of these bulbs in (direct-replacement!) and I'm back to having a green light and the water is being treated for microbes.

Bulbs Don't Work
I bought this intending to replace my failed bulb that came with my humidifier. The bulb I got did not remove the "Change Bulb" indicator. I asked Amazon for a replacement, which they sent, but the second bulb had the same issue.

Did not Work in my Honeywell HCM-350 Cool Mist Humidifier
It looks the same as the other bulb, but doesn't work and doesn't reset the change bulb indicator light. I hope I can return it.

This bulb is not 2.5" long and not 1" in diameter. It is exactly the same size as original.

It was a replacement UV bulb for Honeywell humidifier. It took a lot of effort to access it and replace it. I strictly followed Honeywell's maintenance instructions and also discussed with their technical representative. The light is supposed to turn green if the bulb is working and it did not. This is extremely frustrating. You should check the supplier's quality control before selling their products.
