The difference between a BR20, BR30 and BR40 is actually the size or diameter of the bulb. The number indicates 8 inch increments. For example, a BR30 is 30/8 inches or 30 divided by 8, which equates to a diameter of 3.75.
BR20 | BR30 | BR40. PAR lamps (short for Parabolic Aluminized Reflector) are lamps with spotlight functions, i.e. they generally emit less than 45 °.
R20 can be a PAR20 or a BR20. The main difference between the 2 is the angle of the light beam. BR diffuses the light with a beam angle of 120 degrees, while PAR produces focused light with a beam angle of 40 degrees.
PAR30 lamps are widely used in recessed lighting and track lighting, so they have short and long necks to suit this use. PAR30 short necks are most commonly used in track lighting, while long necks are often used in recessed lighting. BR30 lamps do not offer this option.
For general lighting, most of the boxes are 4 or 5 or 6. You can’t choose BR40 bulbs for 4 boxes, they are too big. For 5 boxes, a BR30 fits with little space on all sides, while a BR40 fits with little or no space on the sides.
Aluminized parabolic reflector
5 different types of bulbs: bulbs are typical bulbs. Fluorescent lamps: Fluorescent lamps are more complex than incandescent lamps. Compact Fluorescent Lamps (CFL): Halogen Lamps: Light Emitting Diode (LED):
It’s actually easier to understand than you might think. The difference between BR20, BR30 and BR40 is actually the size or diameter of the bulb. For example, a BR30 measures 30/8 inches or 30 divided by 8, which equates to a diameter of 3.75. The same example applies to a PAR38.
HMI (Hydrargyrum MediumArc Iodide) is a type of light that uses an arc instead of an incandescent lamp to produce light. Efficiency: 2 to 5 times more efficient than incandescent lamps. As a result, they consume less energy and are less efficient.
As you can see, the PAR38 is larger in diameter than a PAR30 bulb or housing. Depending on the appliance, the plug of the PAR38 bulb may not even reach the socket and, if so, the bulb will protrude from the light instead of sinking into it.
(e.g. E12 has a diameter of 12mm) There are four common sizes of screws for mains voltage lamps: Chandelier: E12 (diameter 12mm) Middle class: E17 (diameter 17mm) Medium or standard: E26 ( diameter 26 mm) mm) Hump: E39 (diameter 39 mm)
PAR stands for aluminized parabolic reflector. BR stands for Bulged Reflector.
This number indicates the diameter of the bulb as 1/8 inch. For example, a PAR38 (1/8 x 38) or 4 lamps is wide.
A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp widely used in commercial, residential and traffic light lighting. Create a very focused beam.
LED light sources and classic recessed spotlights are not always compatible. Some LED lights used in halogen and incandescent bulbs can cause a heat sensor in your home to activate the on / off switch.
Use the actual size scale (calibrated in eighths) to determine the size of a light bulb. Place the edge of the lamp you want to identify on the top of the scale and measure the approximate diameter by reading the measurement on the opposite edge of the lamp.
BR30 lamps provide soft, focused light and are typically used in home lighting fixtures, recessed spotlights and / or track lighting. Their lighting is less accurate and less shaded than PAR lights, but they are great for lights that use dimmers.
So far we have used 65W BR30 incandescent lamps or 75W PAR30 long neck halogen lamps in 5 6 "recessed spotlights.

LIFX BR30.If you are replacing a traditional bulb with a floor or pendant lamp, the A19 shape will suit you better, the shape will diffuse the light over a larger area than the BR30 more focused and the smaller size fits more sockets.
