Change the light bulb for apartment fire alarm to LED.

Since the light bulb for the fire alarm of the mansion property apartment often runs out, I changed it to LED. Just by turning the cover to remove the existing bulb, simply replacing the same product, it is easy to complete the work. The brightness did not change so much and there was no discomfort at all. I would like to introduce it to other apartments in order. We are waiting for products that can handle even low voltage to high voltage.
I replaced an incandescent lamp that was easy to cut with an LED. It is a thing exchanged frequently by an important device. Lifetime is 30,000 hours and about 3 and a half years. There is nothing I'm happy about if you have a New Year in Heisei 30, but I have to wait more than three years to find out the result. The light bulb itself was a red light, but the cover was also red, so I was worried that it would not be dark, but even if I covered it did not fall much. I only bought it for trial, so if the next incandescent lamp goes out, other bells will also change to this product.
There is only one alarm system, I purchased 6 coffee because it is 5 stories. One keeper is spare. Brightness is about half of the light bulb, but it can be confirmed sufficiently as a pilot lamp of energization. Because I keep it for 24 hours, I think that I will keep it nearly four years. I think whether the frequency of lamp replacement will be less. It will be a little power saving, it is recommended.
