Anyone notice gafftapegreenia posted a photo on the left of a different non-BR lamp? Than derekleffew later brought up this lamp type to the conversation?
One in the same person or teaming up to
play a trick on all of you?
By the way, shop at a home center, you get what their buyer's think you will buy. Shop from a distributer and you can have what ever you wish including Fushia in color if desired, much less dipped or tuff coated. Some high wattage versions even come with collector grids or are
ANSI coded as Photo Flash/Flood lamps.
I find the glass on a
PAR lamp is often just a wee
bit thicker than any BR, R, or ER lamp thus a
bit more damage resistant for
portable fixtures, and tend to use R-Lamps for a powder puff like soft lighting
effect the
PAR won't give. (Miss any? How about HYR lamps, KR lamps, not mentioning K-19 lamps.)
Also, there are some krypton and
halogen R-type lamp types in addition to plant light, black light, neodymium and not all
PAR lamps are
halogen.
Not sure where my notes are from on these descriptions:
BR = R-Lamp with
Par Like Shape, (Squat test Reflecting area and
Lens, Seemingly Widest
Beam Angle)
Binary Reflector
ER = R-Type Lamp Shape With Longest Elliptical
Reflector Shape, Seemingly Narrowest
Beam Angle. An
incandescent lamp with an elliptically-shaped
reflector. This shape produces a
focal point directly in front of the lamp which reduces light absorption in some types of luminaries. It is particularly effective at increasing the efficiency of baffled downlights.
K = Milk
Bottle/Beer
Bottle Shaped
Bulb. (Arbitrary Designation)/Narrow focus Directional
Reflector.
PAR =
Parabolic Aluminized
Reflector Par lamps rely on both the internal
reflector and prisms in the
lens for the control of the light beam.
R = R-Lamp
Reflector Spotlight, Blown Glass
Globe Shaped
Reflector and
Lens, Very Rounded.
R-57/R-60 = BR or R lamp shape with coned/nipple top instead of rounded.
RP = R-Type lamp with a
Parabolic Reflector and more straight angular sides and sharper angles. Bow Shape Lamp, Sharp arc like angles, all sides with approx. the same arc & angle.
