I'm selling my two single lens row Derby style disco lights as I've grown tired of them and wish to make room for something else. They're Ness brand and these Derbys are called "Prancer". Here is a photo I found on the web of what the units look like (note that the photo shows a "VEI" version but the Ness version is exactly the same): They come with the original box, packing material, a safty cable, and a gel to make the beams dimmer. You'll need to supply a clamp if your mounting them on a beam or truss. These projectors use two 64514 300watt bulbs each however mine have only one bulb for each projector because the two bulbs in each were too bright and kept on tripping the house circut breakers. I'm asking $150.00USD for both of them plus shipping (original cost for one was ~$120.00USD). US customers only as if your overseas you'll be paying way too much for the shipping most certainly.
