For example: E27 indicates that the lamp is spiral, the thread inner of shells is 27mm. E27 is the lamp holder that we usually use for of incandescent lamp. E14 is smaller than E27, E40 is larger than E27. E40 is mostly used for special lighting, usually large power lamps use E40 lamp holder such as 1000W metal halide lamp.

B15, B22 etc. B means that the lamp holder and the lamp binding mode is bayonet, number (15/22) indicates for the inner diameter of shells bayonet. For example: B22 indicates that the lamp is bayonet, the inner diameter of shells bayonet is 22mm.

GU10 etc. GU is our daily use bayonet. G indicates that it is plug-in, U indicates that lamp cap represents U-shaped, number indicates that the center instance of lamp pins(Unit is mm).

MR16, MR11 etc. MR is plug-in, partial lighting small spotlights usually use this type lamp cap. Generally small spotlight has two pins, which is easy installed. MR16 refers to the maximum outer diameter of 2 inches lamps with a multi-faceted reflector. MR11 is smaller than MR16. MR: Multiface Reflect. Multi-faceted reflector (Lamp cap), number indicates the caliber of lamp cap(Unit is 1/8 inch). MR16 caliber =16*1/8=2inches, which is about 50mm.

PAR lamps generally have PAR30, PAR36, PAR46 and PAR56. Length is long or short. It is also called downlights, which is used for lighting stage and changing dynamic color. It is a common lamp on stage. It is gradually being replaced by LED PAR lamp now, because the power consumption is relatively large.
