Where is it dark? There is no problem at all! It is! Although the evaluation that LED is dark was much uneasy, I think that it is almost equivalent to a normal bulb 100 watts. It is said that it is directly under type, but it does not matter at all. It was too bright to use for the toilet (laugh). Speaking of the difficulty, I'll be late for a breath from switch on. I can only get used to this, and nobody cares. I would like to exchange all factories and offices if there is an electric light.
