I have received and installed the lamp about a month ago. Installing is not super easy but doable, the circular fluorescent tube supplied with lights very nice uniform and has for our ca 12m² room a pleasant amount of light. Although the plastic cover makes at first sight a cheap impression, but if it is on the ceiling, you can not see that and it looks almost like glass. What we were told in stores is the lamp does not keep very long, I can not yet say for a month.
