I've owned this for over 10 years, but I don't know where I got it. The lamp life is 3000 hours, and I don't know how many hours it's been used, so I'm selling it as junk, but it still works. The light itself is reasonably bright, and it doesn't seem like it will die immediately, but the lifespan is unknown. No box or manual. Only the main unit, a soft case, and a 15-pin cord. No power cable.
