For a buy of five, anything more is an unnecessary expense. For me personally, incandescent lamp light is more calming. has benefits 4+ assembly required. There is a little joint where the transparent plastic fits unevenly to the case, as if it had previously been dismantled and unsuccessfully put back together. This small connection does not significantly detract from the product's appearance because, despite its high quality, China is a country where such assembly is common. Everything works perfectly, everything is provided (cable length, cable attachment, etc.), and installation was not difficult. looks chic, current, and young. I like how the form factor can be adjusted to change the height of the light source (cables and cables make this feasible). Cons: LEDs still aren't able to produce a typical spectrum, in my opinion. We frequently turn it on for reading and lesson work (for which it was actually purchased). Application for regulating light that is utterly corrupt. Of the three phones, one was essentially linked before going through the manual and reset modes. I had to buy a remote control, which wasn't inexpensive, but the Chinese gave us one anyhow. The kit has no battery.
