DIAMOND LAMPS Using the same genuine, original bulb as supplied to the Projector Manufacturer, a Diamond Lamp is a lower cost alternative that does not compromise quality. Diamond Lamps have authorised supply of both Philips and Osram bulbs and are seeking supply of the other bulb manufacturers (Osram, Ushio, Phoenix, Iwasaki (Eye), Matsushita and Epsom). Complete with a new chassis, the Diamond Lamp gives identical performance to the Original Manufacturers lamp with an unprecedented 4 month warranty. Diamond Lamps are endorsed by leading bulb manufacturers and guarantee uncompromised performance.
