What is the difference between br20 and br30?

Answer

The difference between a BR20, BR30, and BR40 is actually the size or diameter of the light bulb. The number represents increments of an 8th of an inch. For example, a BR30 is 30/8ths of an inch or 30 divided by 8 which equals 3.75″ in diameter.

In this way, what does br20 mean?

BR20 | BR30 | BR40. PAR (short for Parabolic Aluminized Reflector) bulbs are lamps with “spot light” features, meaning that they provide a beam spread that is typically lower than 45°.

Furthermore, what is the difference between br20 and r20?

 R20 can either be a PAR20 or a BR20. The main difference between the 2 is the beam angle of the light. BRs spread the light with a 120 degree beam angle, while PARs create a focused light with 40 degree beam angle.

Beside this, are par30 and br30 interchangeable?

PAR30 bulbs are commonly used in both recessed lighting fixtures and track lighting, so they come with short neck and long neck options to accommodate this usage. PAR30 short necks are more often used in track lighting while the long necks are often used in recessed lighting cans. BR30 bulbs do not offer this option.

Can I use br30 instead of br40?

For general lighting, most cans are 4″ or 5″ or 6″. For 4″ cans, you cannot choose BR40 bulbs — they’re too big. For 5″ cans, a BR30 will fit with a little space to all sides while a BR40 will fit with little to no space on the sides.

HMI (Hydrargyrum Medium-Arc Iodide) is a type of light which uses an arc lamp instead of an incandescent bulb to produce light. Efficiency: 2 to 5 times as efficient as incandescents. This means they use less power and run cooler.

Can you use par30 instead of par38?

As you can see, PAR38 has a larger diameter than a PAR30 bulb or can. Depending on your fixture, the PAR38 bulb’s connector may not even reach the receptacle, and if it does, the bulb will protrude past the fixture rather than being recessed.

What are the different light bulb base sizes?

(For example, E12 has a diameter of 12 mm) There are 4 common sizes of screw-in sockets used for line-voltage lamps: Candelabra: E12 (diameter of 12 mm) (diameter of 12 mm) Intermediate: E17 (diameter of 17 mm) (diameter of 17 mm) Medium or Standard: E26 (diameter of 26 mm) (diameter of 26 mm) Mogul: E39 (diameter of 39 mm)

What is par38 mean?

PAR stands for Parabolic Aluminized Reflector. BR stands for Bulged Reflector. What does the number after PAR or BR mean? This number is indicative of the diameter of the lamp in terms of 1/8ths of an inch. For example, a PAR38 bulb is (1/8 x 38)” or 4 ¾” across.

What are par lights used for?

A parabolic aluminized reflector lamp (PAR lamp or simply PAR) is a type of electric lamp that is widely used in commercial, residential, and transportation illumination. It produces a highly directional beam.
