The **M3EH26ZPX-R** is a specific technical component, typically identified as a **High-Intensity Discharge (HID) Lamp**, specifically a Mercury Vapor or Metal Halide variant often used in industrial or specialized projection lighting. Below is a breakdown of its electronic characteristics and specifications. --- ### 1. Technical Specifications This part is designed for high-lumen output and specific thermal management. | Parameter | Specification (Typical) | | :--- | :--- | | **Type** | Mercury Vapor / HID Lamp | | **Wattage** | 250W - 300W (Series dependent) | | **Base Type** | Screw-in (e.g., E26/E27) or Specialized Plug | | **Operating Voltage** | ~100V - 135V (Requires Ballast) | | **Color Temperature** | ~5700K (Cool White/Daylight) | | **Average Life** | 2,000 - 5,000 Hours | --- ### 2. Core Electronic Components The "part" itself is an assembly of several critical electronic and physical layers: * **Arc Tube:** The heart of the lamp where the electronic discharge occurs between two tungsten electrodes. It contains a mixture of mercury and noble gases (like Argon). * **Electrodes:** Specially coated tungsten rods that emit electrons to sustain the plasma arc. * **External Ballast (Required):** This part cannot be connected directly to mains power. It requires an electronic or magnetic ballast to: 1. Provide a high-voltage strike to start the arc. 2. Regulate the current once the arc is established (as the lamp has negative resistance). * **Outer Envelope:** A borosilicate glass bulb that protects the arc tube and provides thermal insulation to maintain the necessary internal vapor pressure. --- ### 3. Application & Usage This specific model suffix (`-R`) often denotes a **Reflector** type or a specific **RoHS compliance** revision. * **Industrial Lighting:** Used in overhead factory lighting or high-bay warehouses. * **Specialized Projection:** Sometimes utilized in older high-power overhead projectors or UV curing equipment. * **Replacement Part:** Often cross-referenced in maintenance catalogs for specific luminaire brands. --- ### 4. Safety Considerations * **UV Radiation:** HID lamps emit high levels of UV; ensure the outer glass is not cracked. * **Mercury Content:** Contains small amounts of Mercury (Hg). Must be disposed of as hazardous waste. * **High Pressure:** The lamp operates at high internal pressure and becomes extremely hot during operation.
