Runco LS-5 DLP with spare bulb and screen

We just moved to a smaller house, and I have no room to set my home theater back up. I was extremely happy with this projector because it throws a such a sharp and vibrant picture. It remains in perfect condition it its original box with about 400 hours on it, ready to ship. As the original owner, I paid $5k new for this unit 2 years ago and it is worth every penny. I will let it go for $1800. I will include a new spare bulb ($300 value) at no additional cost. The unit will also come with a complete ceiling mount, as well as 110 inch screen (Paid $600 new).

If it has 1.3x zoom it's the 1.85-2.40 zoom lens. The short throw 1.56-1.86 zoom lens only has 1.2x zoom.

Hope this isn't a dumb question, but if i am interested in it how does that lens work? If I have a 106" screen with a mount 13' back, will it work? i tried looking this up online but couldn't understand how to figure it out. I am looking for one for a relative who loves runco and is looking to buy one used. i tried to sell him my sim2 but he wants a runco.

It works like all other projection lenses. You just need to abide by the throw factors of the lens. For the stock throw lens the throw is 1.85-2.40. The throw range of the lens is directly related to the screen width (not diagonal, width). So it's imperative that you know the size of your screen as well as where the projector is going to be placed to know which lens option will work for you with any projector. So for example, if we had a screen that was 100" wide we do the simple calculation to see where the projector can be placed to get an image that large. 1.85 x 100 = 185" or 15.42' and 2.40 x 100 = 240" or 20'. So this means if you have a 100" wide screen, the projector's lens can be placed anywhere from 15.42 feet to 20 feet from the screen and still have enough zoom to fill the screen.

The short throw lens is 1.56 x 100 = 156" or 13' and 1.86 x 100= 186" or 15.5'.
