Modify a Spot Light…

A spot light is a focused, restricted Source Of Light. Its cone-shaped beam is brightest in the center and is focused on a specific area of a model. Spot lights can be edited for intensity, color, position, and beam spread. The Spot Light tool is available in PhotoView 360. You can edit it under PhotoView 360 Lights or by using the SOLIDWORKS Lights tool. To add and modify a spot light in your model, you can follow these steps.

Cone angle

To simulate the appearance of real-world luminaires, spot lights should have a non-zero cone angle. This setting mimics the shape of a real-world parabolic reflector and light bulb when they are packaged together. In addition, a Hollywood-style searchlight with a large lens radius and small cone angle creates an almost parallel beam. The intensity of the beam gradually diminishes with distance. The volumetrics of the scene should be used to better understand this parameter.

In addition to the Penumbra Angle, you can also control the Cone Angle by setting the Outer Cone Angle. The Cone Angle controls the angle at which full light intensity enters the cone of light. A lower Inner Cone Angle produces a smaller spot, and a higher value creates a larger one. The Cone Angle is variable, but cannot exceed the Outer Cone Angle, which is 179 degrees. Another option is the Outer Cone Falloff, which controls the amount of light and penumbra outside the projected spot.

The Cone angle of a spot light defines how the light will be focused. The larger the value, the wider the cone is, while the smaller the value, the tighter the cone. However, this is not always possible in practice, and sometimes it’s not possible to set the Cone Angle precisely in software. The best way to determine the Cone Angle of a spot light is to perform a virtual scene test using an example.


The falloff angle and radius of a spotlight define The Depth and width of the spot. The latter is the angle at which the intensity of the light drops off. As the radius and falloff angle are equal, the light intensity will drop rapidly at both locations. The intensity of the light inside the inner cone will remain uniform, while the intensity at the outer cone will begin to diminish. Both parameters affect the intensity of light, so it is important to understand them before setting up your spotlight.

The Radius parameter in a spotlight is used to simulate the beam of light from a notional point source. A non-zero Radius gives a softer effect, while a zero value gives hard shadows. To use this parameter, make sure the light source has a spherical shape. In real life, the Radius must be less than 0.75 to simulate a spherical light source.

A Spot Light emits light from a single point in a cone shape, and it can be used to simulate flashlights or lampposts. The Radius of Spot Light is the distance from the light source, and the Inner Cone Angle controls the height of the cone. A large radius will give you soft shadows, while a small radius will create hard shadows. The effect of the Radius depends on the size of the model, so a higher value may be required for larger models.

Color temperature

The color temperature of a spot light is important to understand. This is the hue of light that appears in different environments. Light is measured in Kelvin, and lower numbers are warm while higher ones are cooler. Although the temperature of light is important for the way it looks, it is not the actual bulb temperature. The color temperature of a spot light should match the ambiance you’re trying to create. Read on to learn more about color temperatures and how they can affect your space.

To understand the effects of color temperature on human perception, it’s important to consider the difference between warm and cool light. The warmer CCT lights produce more vibrant colors. The cooler CCT lights produce a cooler, bluer light. However, there’s a middle ground. While warm colors appear warmer, blue is often the more common choice when it comes to spotlights. Therefore, it’s important to understand the difference between the two before you purchase a new spot light.

In general, the warmer the color temperature, the higher the CRI. While the warmest temperature is best for white light, a low-key color temperature is perfect for accent lighting. Candlelight, for example, is considered “warm” compared to the coolest temperature. This color temperature is commonly used around entrances, fireplaces, and spas. However, it’s best to choose a color temperature that complements the environment in which you plan to install it.


One way to improve the CRI of a spot light is to make it brighter. Higher CRIs give the appearance of brighter light in a certain application, such as reading or studying. A high CRI also means the bulb will use less power and can save energy. Various types of lighting bulbs have high CRI levels, including LEDs, halogen, and metal halide. Here are some tips for choosing the best type of lighting for any application.

The CRI of a spot light is a quantitative measurement of the colour rendering capability of the source. The higher the CRI, the more natural and realistic colours the source can render. For instance, if you are working on an art project and want the light to look as natural as possible, you should buy a light with a high CRI. However, if you are unsure of what the CRI of a light fixture means, you can use the CRI of a natural source as a reference.

Another factor to consider is the color temperature. Color temperature is measured in Kelvin. A warmer temperature will set the right ambiance in a room while a neutral temperature will be more suitable for a workspace. Ultimately, you will have to decide what is best for your environment. But, a minimum of 80 CRI is a good rule to follow. A CRI in the 90s is an exceptional value, as it will give you almost perfect colors. Any slight discrepancies in the colors won’t be noticeable to the human eye. A CRI of 90 or higher is also recommended for hospitals, museums, print studios, and retail shops.

IP degree of protection

To select the right spot light for your home, consider the IP degree of protection. A low IP rating is suitable for indoor applications but may not be waterproof. You can also use low-rated lights outdoors provided they are protected from direct exposure to rain and snow. However, if you live in a climate with high dust and water levels, a high-IP rating is the best choice. Listed below are some common uses for high-IP-rated lights in your home.

The IP rating is important to note because it indicates how well the lighting is protected from various types of liquids and solid objects. This rating will tell you where you can install the light and how much moisture it can safely come into contact with. You can also learn the definitions of each type and find out whether a particular light will be protected by an IP rating. If you are unsure about the IP rating of a spot light, consult the manufacturer’s manual to learn more about this metric.

To find the IP rating, look for two different sets of digits. The first number will indicate whether the light or fixture is protected against solids. The second number will tell you how waterproof it is. Generally, a higher IP rating means the light or fixture is waterproof and will not be damaged by solids or liquids. This rating will be displayed on the label. If the IP rating is lower than what is stated, there is no reason to purchase it.

Energy efficiency

LED spotlights are a great choice for energy efficiency. Although they’re more expensive up front, LED bulbs use 90% less electricity than halogens. Not only that, but LEDs last much longer than halogen bulbs, too. First Lighting guarantees their LED spotlights to be of high quality. Read on to learn more about LEDs and their many benefits. They’re an excellent choice for a wide variety of uses.

PAR20 bulbs are 2.5 inches in diameter, common in smaller homes with lower ceilings. They produce 13W of light and use the same E26 Edison screw base as standard A19 bulbs. These lights operate on mains voltage. PAR30 bulbs are larger, measuring approximately 3.75 inches across, and are commonly used in larger ceiling applications. While PAR20 bulbs use the same E26 Edison screw base as their counterparts, they use different energy-efficient technologies.
