What is an LED PAR Bulb?
PAR (Parabolic Aluminized Reflector) light bulbs are reflector light bulbs that have an aluminized reflector in a parabola shape. They are covered with a hard glass lens to control the light beam. This glass cover is available in a variety of beam angles from narrow spot to wide flood.
What are the uses of a PAR bulb?
PAR light bulbs can be used outdoors unprotected because their glass shell withstands adverse weather. PAR light bulbs are also used for down lighting applications, in recessed cans, and in track lighting situations like residential, retail, museums, and art gallery applications.
What is the difference between a PAR and BR bulb?
PAR floodlights have a flat lens and are available in an assortment of beam angles.
Narrow Spot, 5-15 degrees
Spot, 16-22 degrees
Narrow flood, 23-32 degrees
Flood, 33-45 degrees
Wide Flood Beam, over 45 degrees
BR (Bulged Reflector) floodlights have a curved lens that have a wide flood beam angle, over 45 degrees.
What does the number following PAR mean?
The numerical value represents the diameter of the bulb in 1/8 of an inch. Typical sizes include PAR16, PAR20, PAR30, PAR30 long neck, and PAR38.
20 is 2.5 inches
30 is 3.75
38 is 4.75 inches
2700K - 3000K – provides an ambient, intimate, and personal mood with its warm white light that is ideal for living rooms, family rooms, and hospitality environments.
3500K - 4100K – provides a clean and efficient neutral white light that is ideal for kitchen, bath, garage or commercial applications.
5000K - 6500K - provides a vibrant and alert cool white light that is ideal for commercial, industrial, and institutional applications.
What is a beam angle?
The beam angle of an LED bulb is the angular dimension of the cone of light from the lamp. It encompasses the central part of the beam out to the angle where the intensity is 50 percent of maximum.
For most household ceiling fitted applications, a beam angle of 30 or 40 degrees would be sufficient. For outdoor applications, a wider beam angle of 60 to 120 degrees is preferred to cover a larger surface area.
