What is PAR Bulb
A PAR bulb, short for parabolic aluminized reflector bulb, is a type of lamp commonly used in the lighting industry. It is characterized by its parabolic reflector, which helps shape and direct the light output in a specific direction. PAR bulbs are known for their ability to produce a highly intensified and concentrated beam of light, making them ideal for applications where focused and controlled lighting is desired.

PAR bulbs are available in various sizes, denoted by the PAR designation followed by a numerical value indicating the lamp diameter in eighths of an inch. Common sizes include PAR16, PAR20, PAR30, PAR36, and PAR38. The diameter of the bulb determines the spread and coverage of the light.
These bulbs can utilize different types of light sources, including incandescent, halogen, HID, or LED. LED PAR bulbs have gained popularity due to their energy efficiency, long lifespan, and versatility. They offer the advantage of being dimmable, allowing users to adjust the brightness according to their needs.
PAR bulbs find applications in a wide range of settings, such as track lighting, landscape lighting, stage lighting, and architectural lighting. They are valued for their ability to provide focused illumination, highlighting specific areas or objects. Additionally, PAR bulbs are often used in outdoor flood lighting due to their high light output and durable reflector housing.

Domande frequenti
Il valore PAR è uguale ai Lumen
Il Lumen è un'unità di misura che quantifica la luminosità percepita dall'occhio umano da una sorgente luminosa, e viene misurato in foot-candle o LUX. D'altra parte, la PAR (radiazione fotosinteticamente attiva) si riferisce all'energia luminosa misurata come flusso fotonico quantico che le piante utilizzano per la fotosintesi.
A cosa serve un proiettore PAR 64
Tra tutte le lampade PAR disponibili, la lampada alogena al tungsteno PAR64 da 1000 W è comunemente utilizzata per l'illuminazione nel settore dello spettacolo. Questa specifica lampada presenta un diametro della lente di 8 pollici ed è disponibile in 4 diverse ampiezze del fascio, che vanno dallo spot molto stretto al flood ampio.
L'aggiunta di più luci aumenta il valore PAR
No, l'aggiunta di più luci non raddoppierà il valore PAR. Tuttavia, aumenterà il valore PAR nelle aree in cui vi è una sovrapposizione dei fasci di luce.
What Is the Difference Between A19 and BR30
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.
What Is the Difference Between PAR20 and PAR30 and PAR38
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.
What Is the Difference Between PAR and R Bulbs
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.
What Are PAR Lights Used For
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.
Can I Use PAR30 Instead of PAR20
PAR30 bulbs are a great choice for track lighting fixtures and recessed can applications. They are particularly suitable for these types of lighting setups.
Posso usare una A19 al posto di una PAR38
Sia le lampadine A19 che quelle PAR38 presentano un aspetto simile a qualsiasi altra lampadina A19 o PAR38 standard. Questo è essenziale poiché devono essere compatibili con gli apparecchi di illuminazione standard. In generale, la lampadina A19 è adatta per la maggior parte degli apparecchi, mentre la lampadina PAR38 viene utilizzata più comunemente nei fari da incasso e in altri apparecchi specifici.
How Many Lumens Is a PAR30
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.
