 Ideal Applications for LED PAR Bulbs

LED PAR16 Bulb for Retail Display

PAR16 BULBS are best used for narrow to very narrow beam spreads such as in retail stores, museums, art galleries, and display cases.  PAR16 bulbs can also be used for both interior and exterior applications.


LED PAR20 Bulb

PAR20 BULBS are perfect for interior lighting fixtures, such as  bulbs have versatile beam capabilities which give you more options for covering the surface area.  For downlighting applications, PAR20 bulbs work great in areas that require dimmability and decorative abilities.


LED PAR30 Bulb

PAR30 BULBS are ideal for track lighting fixtures and downlighting applications.  PAR30 bulbs are great for larger rooms where multiple light fixtures are being used.  In some applications, PAR30 bulbs can be used for patio lighting, particularly covered patios for wet location rated bulbs.


LED PAR36 Bulb

PAR36 BULBS are most often found in commercial settings, such as office building where downlighting is needed.  In offices, PAR36 bulbs can cover a larger surface area with a broader beam angle without using too many fixtures.


LED PAR38 Bulb

PAR38 BULBS are primarily used for outdoor lighting.  PAR38 bulbs can be used as general flood and safety lights but can also be used for landscape lighting because of their wide beam angle. 


What is the Color Temperature (CCT) for LED PAR Bulbs?

Visual Color Temperature for Light Bulb Diplay

The color of an LED PAR Light Bulb is measured by its color temperature (CCT), which is identified by a number on the Kelvin (K) scale.  A Kelvin is a thermodynamic temperature scale where one-degree Kelvin corresponds to the same temperature difference of one degree Celsius (5)

This means for every one-degree increase in Kelvin, the light temperature can be visibly measured.  The Kelvin scale is how the visible differences of a light bulb’s temperature are displayed in lighting.  All light bulbs are measured using the Kelvin scale to determine the CCT.

Which color temperature do I need?

The temperature of a light bulb refers to the hue or tone of the light. Higher color temperatures produce a bright, sky blue white light, while lower color temperatures provide and warmer, yellow-orange glow similar to candle light. First determine the ambience of your space, then select the right color temperature for your PAR bulb, and then search our vast selection of LED lights for your convenience:
