When replacing the lamp
On 2017-02-22 14:01:14
A quarter of the item was a defective item that repeatedly turns off the light.
I use it for the lighting of the common part.

I bought it with a fluorescent lamp for illumination of the common part. Since considerable number of years of exchange will occur, we bought it all together. There was no problem in performance. I am also grateful to Cospa.

There are several ceiling lights like 20 W × 2 or 20 W × 4 so we bought it all together. For now, there is no problem, it is cheap and it is saved.
