What is PAR Bulb

Lumen is a unit of measurement that quantifies the brightness perceived by the human eye from a light source, and it is measured in foot candles or LUX. On the other hand, PAR (photosynthetic active radiation) refers to the light energy measured in quantum photon flux that plants utilize for photosynthesis.

Of all the PAR lamps available, the PAR64 tungsten halogen lamp with a wattage of 1000 is commonly used for lighting purposes in the entertainment industry. This particular lamp has a lens diameter of 8 inches and can be found in 4 different beam spreads, ranging from a very narrow spot to a wide flood.

No, adding more lights will not double the PAR. However, it will increase the PAR value in areas where there is overlap in light.

The A19 bulb is more suitable for floor lamps and hanging ceiling fixtures due to its curved shape, which provides dispersed lighting. On the other hand, the BR30 bulb is ideal for recessed fixtures in the kitchen or hallway, as well as track lighting, thanks to its shape and reflective coating that casts direct lighting.

A PAR20 lamp has a diameter of 2 ½ inches. On the other hand, a PAR30 lamp has a diameter of 3 ¾ inches. Lastly, a PAR38 lamp has a diameter of 4 ¾ inches. These PAR lamps commonly use the E26/E27 medium screw base.

PAR LED Light Bulbs differ from R type bulbs in that they feature a specially designed aluminum reflector that focuses and intensifies light in a single direction. These bulbs are equipped with two covers, one made of reflective aluminum and the other being a glass envelope. The additional thickness of these covers contributes to their heavier weight compared to R bulbs.

PAR lights, also known as PAR lamps, are directional lights commonly used in can lights or spotlights. They were originally designed for use as headlights in road vehicles. The earlier versions of PAR lamps used incandescent and halogen sealed beams.

PAR30 bulbs are a great choice for track lighting fixtures and recessed can applications. They are particularly suitable for these types of lighting setups.

Both the A19 and PAR38 bulbs have a similar appearance to any other standard A19 or PAR38 bulb. This is essential because they need to be compatible with standard fixtures. In general, the A19 bulb is suitable for most fixtures, while the PAR38 bulb is more commonly used in high-hats and other specific fixtures.

This PAR30 LED bulb uses only 11 watts of power and produces a bright light output of 850 lumens. It is a suitable replacement for a 75-watt flood light bulb.
