HID Lamp Anatomy

The ARC TUBE is the light producing source inside the lamp. There is no filament inside the arc tube, rather gases and a chemistry mix create the light. TUNGSTEN ELECTRODES inside the arc tube provide a jumping off point for an electric arc which vaporizes the chemistry creating light. The glass STEM provides electrical connections…

What is an HID Lamp?

HID lights are High Intensity Discharge lights. HID lamps, or light bulbs, are high-powered light sources. They include Metal Halide lamps and High Pressure Sodium lamps. EYE HORTILUX® HID lamps are manufactured specifically for indoor horticulture. They supply artificial light for indoor plant growth. Unlike incandescent light bulbs, HID lamps do not have a filament.…

Science of Creating Light

High Intensity Discharge (HID) lamps create light by heating up materials inside the arc tube. Metal Halide lamps, for example, heat up the scandium inside the tube. In its atomic form, a scandium atom is composed of a nucleus surrounded by 21 orbiting electrons. For this demonstration we’ll focus on only three of the orbiting…
