Panasonic iD Series i-Style LED Base Light XLX2000ENJ LE9, this is a single light bar only. This product cannot be used on its own. It is a light bar to be combined with the base NNLK21509J. This base is not included. The light color is 5000K daylight. The list price is about 12,000 yen. I purchased this for a renovation of indirect lighting for the entrance, but I made a mistake with the light color, and it has not been opened. I purchased it about a year ago and have stored it at home. A qualified electrician is required for installation. Please understand that this is a used item.
