Koizumi Lighting Electric, Panasonic LED Pendant Light Set of 2

This came with the house I bought. It's a very simple LED light. It should lower your electricity bill, right? I immediately removed it and replaced it with one I already had. I looked it up online and one costs 9,000 yen. I'm listing them as a set of two.
Price reduced from 7800 to 7000 to 6500 to 6000.
The length can be adjusted. Thank you.
