I replaced it with an arm light light bulb, 60 W but a slightly dark impression, I thought that the lighting range was ok. The product itself is compact and easy to handle, it seems that the reaction of the fluorescent lamp is also fast. I think that there is no problem if it is a thing with a little W number, but because it depends on the purpose of use, I think that it is a product without problem for normal use.
I used it as lighting of the office entrance. I was attached to a human sensor device, but it was short in 3 months. Because the manufacturer was Ohm Electric, I bought it reliably but cheap goods may be problematic after all.
