Cost of ownership is likely the most important factor in the purchase of a projection system and careful selection pays dividends. The optical efficiency of the projector is likely the largest contributor. A high-efficiency projector requires less power for a given amount of light output, thus directly reducing ongoing operating costs as well as helping to reduce the environmental footprint.
Lamp and filter costs
The cost of replacement lamps is also a factor; the small lamps used in multi-lamp projectors usually last longer, provide redundancy and cost less to replace than the larger lamps used in single-lamp projectors to achieve the same light output. Air filters, which typically must be replaced regularly, are another ongoing expense; a projector than can operate without them provides an obvious advantage.
Low-cost, commodity projectors don’t usually provide the capabilities described above that lead to lower operating costs, hence may actually end up costing more in the long run.
An effective projection system, regardless of its size, must be bright, flexible, reliable, meet the needs of the end user, and all fit within a defined budget. To ensure that all requirements are achieved, the first step is to hire an experienced system integrator to specify what is really required. This valuable step will help to ensure that the right equipment is determined up front, which avoids costly upgrades or replacement purchases later, provides a smoother experience during the installation phase of the project and ultimately delivers the right solution.
