There are only SP washers and 2 flat bolts in the mounting part, so there is no flat washer, so the resin body seems to be drenched. I inserted a flat washer and used it. I do not know how much lighting actually is because I do not have farm work. It is light and I think that cost performance is good because sphere exchange is possible. If it is an LED, it becomes main body exchange, I think whether it will take time in the work of the site, but because of halogen, that point should be saved.
