Lamp holder classification:
The lamp holder (lamp holder) starting with 1 e is a common screw lamp holder, which is the most commonly used one. The number at the back represents the size of the lamp holder. E27 is the incandescent lamp holder we usually use. E 14 is smaller than E27, and E40 is larger than E27.
2. The lamp holder (lamp holder) at the beginning of GU is a bayonet type that we use daily, where G indicates that the lamp holder type is plug-in, U indicates that the lamp holder part is U-shaped, and the number at the back indicates the center distance of the lamp foot hole (in mm), such as GU 10.
3. The lamp holder at the beginning of 3.MR is a common lamp holder for in-line local lighting spotlights. This spotlight generally has two pins, which is convenient to install. For example, MR 16 in the lighting industry refers to a polygon reflector lamp with a maximum outer diameter of 2 inches.
4.MRMR (Multi-faceted reflection) refers to multi-faceted reflection (lamp cup), and the number behind it indicates the diameter of the lamp cup (unit: 1/8 inches). For example, MR 16 × 1/8 = 2 inches in diameter, which is about 50 mm
5.PAR lamps, also known as downlights, emit light beams, which are usually used for stage lighting and dynamic color change. They are common lights on the stage. These lamps generally consume a lot of electricity and have high temperature, and now they are gradually replaced by LED lamps.
6.AR starts with aluminum cold reflection halogen spotlights.
7.G 12 is a single-ended tubular metal halide lamp bulb.
