The range of relative humidity (in percentage) within which the product is designed to operate reliably. Values are expressed as a minimum–maximum interval such as "20 - 80 %" and indicate the acceptable environmental moisture level for optimal performance.

A list of the positions or mounting options where a product can be installed, such as indoor, outdoor, wall, desk, floor, ceiling, or universal. Each value represents a distinct placement scenario that the device supports.

The electrical power drawn by a device while operating in its economy or energy‑saving mode, expressed in watts (W). This value indicates the typical energy usage when the product is set to reduce consumption during normal operation.

The amount of light emitted by a projector, expressed in ANSI lumens. It indicates how bright the projected image will appear under typical viewing conditions and allows users to compare brightness levels across different projectors.

The amount of light emitted by a projector when operating in its low‑power or energy‑saving mode, expressed in lumens (cd/m² for luminance). This value indicates how bright the screen will appear under typical viewing conditions while conserving energy.

The pixel dimensions that a projector can output, expressed as width by height (e.g., 1920x1080). It indicates the native resolution of the projected image and is used to determine compatibility with source content and display quality.

The root‑mean‑square (RMS) power rating of a device, expressed in watts (W). It represents the average electrical power that the product can deliver or consume under normal operating conditions.

The diagonal measurement ranges of screens that the product can project or display, expressed in millimeters and/or inches. It indicates the minimum and maximum screen sizes that the device is designed to handle.

The type of serial communication interface supported by the product, such as RS‑232, RS‑485, RJ‑45, or SATA. It indicates which physical connectors and protocols are available for data exchange with other devices.
