Please note that this item is not subject to discounts. This is a set of 5 duct rail spotlights, ready to install. They are made by Koizumi Lighting Co., Ltd. in 2006. While there is some wear and tear, and some soiling, they have been tested and are in working order (see photo 1). They come with LED bulbs, so they can be used immediately. Please refer to the photos for details on the LED bulbs (photo 15). LED bulbs are consumables, so the remaining lifespan is unknown. Please understand that the bulbs are included as a bonus with the spotlight bodies. We are looking forward to your purchase if you understand that these are used items. Please refrain from purchasing if you are looking for a perfect item. The items will be packaged with the spotlight bodies and bulbs wrapped separately in bubble wrap. When opening the package, please be careful not to damage the product with scissors or a cutter. Thank you. Instant purchase is also welcome.
