Since I always purchased the fluorescent lamp was missing, I substituted it. It seems that the color temperature is slightly lower than usual one and it looks a little yellowish as it is incorporated into the signboard.
I installed it in the toilet, but the moment I turned on it was very dark and it got brighter as it became usable after a long time passed. So it is not appropriate to use a toilet or a kitchen where you need to be bright immediately. I wonder if it is a place that has been on forever.
