This is a set of three ODELIC spotlights. I purchased these as spares and have been storing them. I tested them before listing, and they are in perfect working order. These spotlights cost around 6,000 yen each, even at a discounted price. I've used other inexpensive spotlights before, but these are of higher quality, with beautiful color rendering and ample brightness. While the initial investment is a bit higher, these are long-lasting products, so please consider them. The duct rail is not included.
