Determining the optimal spacing of recessed lights for creating ambient lighting in a room involves considering multiple factors, such as the room's purpose, ceiling height, ceiling and wall characteristics, existing lighting, and the type of light fixtures used.

As a general guideline, for standard 8 to 9-foot ceilings, placing recessed lights around 6 to 7 feet apart and placing the downlights about 3 to 4 feet away from the wall to created balanced and even illumination. Adjustments might be needed for taller or sloped ceilings, possibly requiring slightly closer spacing.

However, it's essential to consider the specific characteristics of your space. Seeking advice from a lighting professional can help you determine the optimal placement for achieving your room's desired lighting effect and ambiance.

Color temperature refers to the characteristic color of light that a light source emits, measured in units called kelvins (K). It is a way to describe the appearance of light based on its warmth or coolness. Lower color temperatures, around 2700K to 3000K, typically emit a warm, yellowish light similar to traditional incandescent bulbs. Higher color temperatures, around 5000K to 6500K, produce a bluish tinted light. Color temperature plays a significant role in setting the mood and ambiance of a space, as well as impacting how colors appear under the light.

LUSA lights provide 3000K at full brightness, and when dimmed below 50%, the temperature warms to 2200K, resembling the lighting seen at sunset. We feel this is the ideal color temperature for home use.

Lumens are a unit of measurement used to quantify the amount of visible light emitted by a light source. Essentially, lumens indicate the brightness of a light. The higher the lumen value, the brighter the light will appear. When choosing lighting products, it's important to consider lumens, as it helps determine how well a light source will illuminate a space or object.

Dimming refers to the ability to adjust the intensity or brightness of a light source. It allows you to control the light output from a light fixture, making it brighter or softer. Dimming can be achieved through various methods, such as dimmer switches, smart home systems, or specialized dimming controls. 

It lets you control the light level to suit different preferences, tasks, or moods. Dimming creates a comfortable atmosphere, saves energy, and enhances visual appeal.

Warm dim is a lighting technology that mimics the inviting and cozy glow of traditional incandescent lighting while dimming, replicating the gradual color shift seen during a sunset. As you lower the intensity of a warm dim light source, its color temperature gradually transitions from a cooler white light to a warmer, amber hue, simulating the soothing ambiance of dusk. This technology is frequently used to create a calming and welcoming atmosphere, where the progression from bright to dim lighting mirrors the serene transition from day to evening.

Yes, LUSA recessed downlights feature natural warm dim technology, which provides warm white light for accurate illumination at full brightness and transitions to a relaxing sunset effect when dimmed, reducing blue light output in the process. Our light module has been optimized to provide exceptional performance, with smooth dimming down to 5%, with any smart home or connected dimmer, forward or reverse-phase dimming. 

The Color Rendering Index (CRI) is a measurement that indicates how accurately a light source reveals the true colors of objects compared to natural sunlight. It's a scale from 0 to 100, with a higher CRI value indicating better color accuracy.

CRI is essential because it helps us evaluate how colors appear under a particular light source. A 90+ CRI ensures that colors are rendered realistically and vividly, creating a visually pleasing environment. Most will notice a significant deterioration of color vibrancy, especially reds, when using an 80 CRI light source.

The round trim helps reduce glare, making it suitable for everyday spaces like kitchens, great rooms, and bedrooms.

The surface trim provides a wide beam angle, making it an excellent choice for closets, hallways, pantries, and showers.

The square trim offers the benefits of our round trim in a sleek, contemporary design. 

Finally, our adjustable trim allows for field-adjustable light distribution, perfect for sloped ceilings or highlighting unique home features. 

All our trims feature stainless steel clips that provide a strong, gap-free hold and are also modular in design, allowing for easy tool-free installation and making it easy to swap out to accommodate any plan changes. 

Our recessed downlights are rated for I.C. (insulation contact) and Air Tight. They are U.L. Certified, making them appropriate for wet locations. They are also in compliance with California Building Energy Efficiency Standard, Title 24 regulations, and have earned the ENERGY STAR designation. Furthermore, the housing is recyclable.

Absolutely! LED recessed downlights are versatile and can be used for general illumination and accent lighting. With the proper placement, they can highlight specific architectural features, artwork, or focal points in a room.

Upgrading to LUSA LED technology offers numerous benefits. It provides better lighting quality with enhanced color accuracy, brightness, and dimming capabilities. The adjustable option adds flexibility to customize lighting angles. Additionally, sleek and modern LUSA downlights enhance the visual aesthetic of your space.

They also significantly reduce energy consumption, lowering electricity bills and contributing to a greener environment. LUSA LED downlights have a longer lifespan, cutting maintenance and replacement costs.

For optimal lighting, we recommend tailoring your choice based on ceiling height, the spacing of lights, and personal preference.

350 lumens will provide softer light and is ideal for niche or soffit lighting.

750 lumens offer a balanced level of illumination in standard-sized rooms.

950 lumens provide a bright and powerful light suitable for taller ceilings or when high-visibility task lighting is desired, such as a kitchen counter.

A retrofit downlight is an LED lighting solution designed for updating existing recessed cans. The term "retrofit" means upgrading the lamp source, often to a more modern technology like LED, and trim, while keeping the existing above-ceiling housing and wiring intact. 

LUSA's retrofit downlights are LED lights that can be easily installed into your current recessed cans. They are affixed to the existing housing using stainless steel clips attached to trims. They must be used with an existing recessed lighting housing with a nominal interior diameter of 4 inches. Trim will cover up to a 4 3/4-inch surface.

LUSA light modules are designed for plug-and-play compatibility with housings featuring male IDEAL connectors.

Check your current housing to identify the connection type to determine if you need an adapter. If your housing does not have a male IDEAL connector, you can select from these adapters for other common connection types.

You'll need a LUSA Edison adaptor if your housing employs an Edison (screw-in) connection. Similarly, if your housing uses a female IDEAL connector or a GU-24 connector, LUSA also offers dedicated adaptors for these. [insert image]

It's important to note that if your housing utilizes a GU-12 connector, it's typically a low-voltage setup and incompatible with LUSA light modules. In such cases, it's advisable to seek advice from an electrician.
