PAR38 BULBS are primarily used for outdoor lighting. PAR38 bulbs can be used as general flood and safety lights. Since these are available in with higher wattage options amongst the PAR series, PAR38 bulbs are perfect when light is required to reach farther, such as two-story ceilings or outdoor fixtures for instance.

We are a leading energy-efficient lighting and smart home brand.

Edison Screw The letter "E" in E26 refers to Edison Screw, the most standard of lamp bases, while the numerical "26" refers to its diameter in millimeters (approximately 1 inch).

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.

parabolic aluminized reflector PAR stands for “parabolic aluminized reflector.” These bulbs have a lamp, reflector, and pressed lens inside the lamp to provide directional lighting. They have a shorter body than BR light bulbs with a bowl shape.

So it's parabolic shaped. It's an anodized aluminum and it's a reflector. So that's par para parabolic anodized reflector and that is a mouthful.

We've lived with dozens of different LED light bulbs over the years, but the standard Feit Electric soft white, daylight, and bright white bulbs stand out as the best-looking, most reliable, and smoothest-dimming LED bulbs available.

I like Feit bulbs for the technology. FEIT has lighting products for every budget and application. As with most other L.E.D. producers the quality and durability has dropped off significantly.

Is E26 a standard bulb? E26 is the base type for standard A19 light bulbs. A19 is the shape and diameter of the bulb, while E26 refers to the screw type (Edison) and the base diameter.

In the U.S, the most commonly used light bulb is known as a “Medium” or “Standard” base. The threaded part of the light bulb that screws into the socket is referred to as the “base”. An E26 base light bulb is another name for a medium or standard base light bulb.

PAR Bulbs – Narrow Beam Angle for Directional Light These work well in applications where directional light is needed, such as in spotlights or retail displays. This is the type of lighting used in theater, and it is also sometimes used to light exterior landscaping features.

PAR lamps and their fixtures are widely used in theatre, concerts and motion picture production when a substantial amount of flat lighting is required for a scene. They are often mounted in can-shaped fixtures known as PARCANs, which can be used to generate colours by fitting them with colored sheets called gels.

The Best Option for Theatre and Stage Performances A clearly defined circle can help draw the audience's eyes, create an effect, or provide a distraction. In addition, PAR lamps can be used to uplight walls and backdrops.

Now the bad news: PAR38 and PAR30 refer to the physical characteristics of the bulbs. PAR = Parabolic Aluminized Reflector, 38 = thirty-eight eighths of an inch, or 38*1/8"=4.75". 30 = thirty eighths of an inch, or 30*1/8"=3.75". As you can see, PAR38 has a larger diameter than a PAR30 bulb or can.

Lumen is a measurement of human eyes ability to perceive the brightness emitted by any light source, and its measured in foot candles or LUX. By contrast, PAR (photosynthetic active radiation) is light energy measured in quantum photon flux which plants "see" to photosynthesize.
