I purchased it before, so it was a very reasonable and good product, so I bought it for lighting of new equipment. Although it is a fluorescent lamp, it is actually a place I would like to make LED lighting, but I decided on this product because the price is still high.
Despite its low cost, the clamp is made of metal, so it seems to be durable. (Inexpensive ones are plastics many and easily broken.) The difficulty is that it is difficult to obtain whether the fluorescent tubes are special. By the way, I searched for it in MonotaRO, but I can not find it. If a general fluorescent bulb can be used, it is economical and good, but unfortunately it can not be used.
