What does par mean when it refers to a halogen light bulb? The below explanation is correct: No, PAR is not referring to the golf game; PAR (Parabolic Aluminized Reflector) is actually the description of the lamp or bulb that goes inside a PAR can. The can is the container where the PAR lamp or bulb goes. The number beside PAR is a measurement that describes the diameter of the PAR lamp or bulb. To figure out the diameter, divide the number next to PAR by eight. For example, if you have a PAR64, divide 64 by 8 and you will have an 8-inch diameter lamp.

What does âIRâ mean in halogen bulb descriptions? The IR (or sometimes HIR) in the description code means ‘infrared’, as you might have guessed, but it does not mean these bulbs are for heat lamp applications. The IR refers to a coating on the halogen capsule which is located inside the reflector of PAR or MR halogen light bulbs.This diagram shows the capsule inside an MR16 reflector. Several layers of durable, thin interference film are added to the capsule wall.n the second example, assume you currently use a number of 50MR16/FL40 bulbs. To cut energy costs without sacrificing the quality of the light, select the lower wattage, IR version of the same bulb, 37MR16/IR/FL40. and get the same light output using about 30% less energy.

What exactly is a PAR type LED lamp, how does it differ from R/BR type LED & CFL lamps? The difference between PAR & BR LED bulbs is minimal, and mostly cosmetic. Basically, the PAR bulb has a flat surface, while a BR bulb has a rounded surface. Given the same lumens, the same size, the same color temperature and the same lumens per watt, it really does not make a difference whether it's a PAR or BR.

- Light bulbs have a wattage and a voltage. The wattage is the strength of the current while the voltage is the type of current. Consumers have a choice of incandescent, halogen, fluorescent, and LED light bulbs.o use a dimmer with a fluorescent light, the bulb must have a dimmable ballast, which will be written on the package or should be advertised if the homeowner is buying online. Some standard dimmers will then be compatible with a fluorescent bulb but not all are.

LED Lighting LED stands for Light Emitting Diodes. LED lighting has no filaments, so they give off heat. LED lighting has a different selection of colors and have a few light show settings. LED bulbs have a very long life span…about 30,000 hours looking at the 5,000 hours of the incandescent and the 6,000 hours fiber optics.

Incandescent An electric current passes through the filament, heating it to a temperature that produces light. Incandescent light bulbs usually contain a stem or glass mount attached to the bulb's base which allows the electrical contacts to run through the envelope without gas/air leaks. Small wires embedded in the stem support the filament and/or its lead wires.

What are Lumens? Think of lumens as a new way of knowing how bright a lamp is. Lumens = Light Output. In simple terms, Lumens (denoted by lm) are a measure of the total amount of visible light (to the human eye) from a lamp or light source. The higher the lumen rating the “brighter” the lamp will appear. We have all bought 50W or 60W conventional bulbs or spotlights in the past expecting a certain level of brightness.

Typically, the output of a 100-watt incandescent bulb is about 1,600 - 1,700 lumens, a measurement of lighting power. Beginning in mid-2011 new labels will be required on light bulbs. When these labels become available, simply look for a lumens rating to choose a replacement bulb. former 100-watt light bulb manufactured on or after January 1, 2011 and sold in California will have to use 72 watts or less. The 72-watt replacement bulb will provide the same amount of light (called lumens) for lower energy cost.

A Glossary of Lighting Terms A lumen is a measurement of light output from a lamp, often called a tube or a bulb. All lamps are rated in lumens. For example, a 100-watt incandescent lamp produces about 1,750 lumens. The distribution of light on a horizontal surface is called its illumination. Illumination is measured in footcandles.

Understanding the Difference Between a PAR 30 and BR 30 Bulb Similarities. Though PAR 30 bulbs offer more options for lighting, both PAR and BR LED lamps are made to easily replace the energy-stealing halogen and incandescent lights. Because of this, both bulbs have the same medium (E26) base for North American sockets. The numbers after PAR and BR, like 30, stand for 1/8 th of an inch. To find the diameter of the lamp, just divide the number after it by 8: e.g., the diameter of a BR 30 bulb is 30/8ths of an inch, or 3.75 inches in diameter. Lighting and Application.

Incandescent light bulb Incandescent light bulbs consist of an air-tight glass enclosure (the envelope, or bulb) with a filament of tungsten wire inside the bulb, through which an electric current is passed. Contact wires and a base with two (or more) conductors provide electrical connections to the filament.
