Just bought an NJD QUARTET. This is a single unit that houses 4 300 Watt lamps with four coloured lenses and barn doors and basically does the same job as four 300 watt Par Cans the only difference being that this unit is super convienient . Replacement lamps are quite pricey but I have found a few on Ebay very cheap. I currently run this lamp with a NJD Euro 4E Controller but I think I will upgrade as it does get a bit hot after a while. Overall very pleased with this purchase.

Are they good as use in a Mobile Disco, or are they designed more for Band use ?
