There are things in life, when you collect Vintage Light Effect, that you don't want and that is selling one, knowing you'll regret it. This is one of them.Not only was this one in a mint condition, it was one of the very rare 200 Watt SN lamps factory build. 99% of the Astro's sold are the 150W, 24V lamps. They are cheaper,burn much quicker. The SN needs time to warm up, but it's twice as bright as the common version. I sold it to a light designer in Holland, Martin Ciesluk. He was very glad with this one..hope he still has it..
