Why Choose 8-inch Recessed Lighting?
Choosing an 8-inch recessed linear light means upgrading from outdated spot lighting to modern continuous illumination, seamlessly utilizing your existing setup, and ultimately obtaining a lighting solution custom-made for your space.
If you’re unsure about selecting the right fixture type, consult our commercial lighting guide.
From Spotty Dots to Continuous Light: The Aesthetic Revolution
Traditional downlights create scattered, spotty pools of light that can cast uneven shadows. The 8-inch recessed linear light emits a continuous, uniform band of light, enabling shadow-free wall washing or clean ambient illumination, significantly enhancing the modernity and visual comfort of a space.
| Recurso | Traditional 8-Inch Downlight | 8-Inch Recessed Linear Light |
| Light Pattern | Scattered, spotty pools of light | Continuous, linear band of light |
| Visual Effect | Uneven illumination, potential shadows | Smooth, uniform, and clean look |
| Best Use Case | Localized accent lighting | Ambient lighting, wall washing, outlining architectural features |
The Perfect Fit for Your Existing 8-inch Can Holes
Still struggling to upgrade lighting through existing cutouts? Here’s the good news: a standard 8-inch (approx. 20cm) downlight hole is the perfect starting point for our custom linear lights. We provide mounting frames tailored to this size and fully customizable lamp lengths, ensuring a seamless retrofit with no additional cutting or patching required, completely eliminating your fitment concerns.
Endless Customization: Your Design, Realized
The core advantage of linear lights lies in customization, far surpassing standardized downlights. You can determine the following key parameters based on your specific spatial needs:
- Custom Length: The fixture can be made to any length to fit your hole spacing or design vision, allowing for perfect single or multi-segment runs.
- Color & Brightness: Full spectrum color temperatures from warm to cool white (2700K-6500K), with adjustable lumen output.
- Optics: Optional accessories like honeycomb louvers or prismatic lenses to precisely control beam angle and minimize glare.
How to Customize: Key Parameters Explained
The customization process revolves around three core decisions to ensure the final result perfectly matches your design vision and functional requirements.
Step 1: Determine Length & Layout
Length is the foundation of customization, determining the visual continuity and integrity of the light strip.
- Key Measurement: Precisely measure the Center-to-Center (CTC) distance between existing (or planned) 8-inch holes in your installation area.
- Layout Recommendations:
Single Long Run: Ideal for narrow spaces like hallways or kitchen countertops to create a seamless linear effect.
Multiple Parallel Runs: Suited for wide areas like living rooms or commercial ceilings, building a modern optical matrix.
Step 2: Select Color Temperature & Luminance
Color Temperature sets the mood, while Luminance fulfills function. Together, they define the ambiance of a space.
- Color Temperature Guide:
Creates a cozy, relaxing atmosphere. Ideal for residential bedrooms, upscale restaurants, hotel rooms.
Offers clear, focused light. Best for offices, kitchens, retail stores, classrooms. - Luminance Reference:
For ambient lighting, suggested illuminance targets: Living room 150-300 Lux, Office 300-500 Lux, Retail focus areas 500+ Lux.

Step 3: Choose Optical Accessories
Optical accessories represent the “advanced customization” of linear lights, directly determining visual comfort and light quality.
| Accessory type | Core Functionality | Applicable scenarios |
| Anti-glare Honeycomb Louver | Significantly reduces direct glare, protects eyes, achieves “light without seeing the source.” | Any space requiring prolonged viewing or optimal comfort, e.g., work areas, reading nooks. |
| Prismatic Lens / Diffuser | Precisely controls beam angle for softer, more uniform light diffusion. | Achieving even wall-washing effects or preventing light spill into unwanted areas. |
| Deep Recessed Design | Uses a physical shielding angle to conceal the light source, a fundamental anti-glare solution. | A standard or basic option for all recessed installations. |

Installation Overview
Key Advantage: Customized Fit
Your existing 8-inch opening is our standard compatible size. Installation focuses on connection and embedding, with no need to modify the opening.
Tools: Screwdriver, voltage tester, glovesFive-Step Installation Process:
- Turn off the circuit breaker.
- Remove the old fixture. Confirm the opening size and wiring condition.
- Connect the low-voltage DC driver’s output to the custom light module’s input (typically a plug-and-play connector). This is a safe, low-voltage step.
- Push the connected linear light module into the 8-inch opening. Use the integrated spring clips or mounting brackets to secure it firmly in the ceiling.
- Snap on the matching matte or glossy trim to conceal the opening edges. Restore power and test the light.
Professional Advice: For complex multi-light wiring, dimmer system integration, or circuit modifications, consultation with a licensed electrician is recommended.
