Step-by-Step Installation Guide
⚠️ Safety First: Always disconnect power at the circuit breaker before working on electrical fixtures. Verify power is off with a non-contact voltage tester.
Step 1: Gather Tools & Materials
Non-contact voltage tester
Screwdriver (flathead and Phillips)
Wire strippers/cutters
Wire nuts or Wago connectors
Ladder or lift
PPE (safety glasses, gloves)
Step 2: Remove Fluorescent Tubes
Carefully remove all fluorescent tubes from the fixture. Set aside for proper recycling—they contain mercury and should not be thrown in regular trash.
Step 3: Disconnect & Remove Ballast
Locate the ballast (usually a metal box inside the fixture). Note: Some installations may have ballasts at a central location rather than in each fixture.
Disconnect the ballast wires:
Black (hot) and white (neutral) from power supply
Wires to tombstones (tube sockets)
Remove the ballast entirely, or leave in place with wires disconnected. Some contractors leave the ballast in the housing to avoid creating a hole.
Step 4: Rewire Tombstones
Connect line voltage directly to the tombstones:
Black (hot) → One end of the strip (typically marked “LINE” or “HOT”)
White (neutral) → Other end of the strip (typically marked “NEUTRAL” or “N”)
💡 Note: Retrofit LED strips use single-end wiring on most models. Follow the specific wiring diagram included with your fixture.
Step 5: Mount the Retrofit Strip
Most retrofit strips use the same mounting brackets as the original fluorescent fixture:
Slide the LED strip into the existing brackets, or
Attach included mounting clips to the housing
Step 6: Make Electrical Connections
Connect the retrofit strip wires to the power supply:
Black to black (hot)

Common Questions
Do I need an electrician?
If you’re comfortable with basic electrical work (changing outlets, installing light fixtures), you can install retrofit LED strips. Otherwise, hire a licensed electrician. Installation typically takes 15-20 minutes per fixture.
What if my ballast is compatible?
Some electronic ballasts work with LED tubes, but most retrofit strips require ballast bypass. Running LED strips through a ballast will cause flickering, reduced life, or immediate failure. Always follow the manufacturer’s instructions.
Can I dim retrofit LED strips?
Standard retrofit strips are non-dimmable. If you need dimming, specify 0-10V dimmable models when ordering. These require additional wiring for the dimming circuit.
What about emergency lighting?
Retrofit strips can be paired with external emergency battery backup units. For new installations requiring emergency lighting, consider new LED fixtures with integrated emergency drivers.
How do I dispose of fluorescent tubes?
Fluorescent tubes contain mercury and must be recycled properly. Contact your local waste management facility or use services like lamprecycle.org to find recycling locations.

📋 General Questions
1. What is an LED linear strip light?
An LED linear strip light is a long, narrow fixture with integrated LED chips. Unlike fluorescent strips that use replaceable tubes and ballasts, LED strips have the light source built into the housing, providing higher efficiency and longer life.
2. How long do LED linear strip lights last?
Quality LED strip lights like the SS-SP05 series are rated for 50,000+ hours of operation. At 12 hours per day usage, that’s over 11 years of maintenance-free lighting.
3. Are LED strip lights better than fluorescent?
Yes, in nearly every application. LED strips consume 40-60% less energy, last 2-3x longer, provide instant start with no flicker, and require zero maintenance. They also eliminate mercury disposal concerns.
4. Can LED strip lights replace fluorescent fixtures?
Two options exist: retrofit strips that install into existing fluorescent housings, or new LED strips that replace the entire fixture. Retrofit is faster and cheaper; new fixtures offer more features and better aesthetics.
5. What does “selectable wattage” mean?
Selectable wattage fixtures have an internal switch that lets you choose between 3 power levels. For example, the SS-SP05-4 (4ft model) offers 40W/50W/64W settings, allowing one fixture to meet different brightness requirements.
📐 Sizing & Selection
6. What sizes do LED strip lights come in?
Common sizes are 2ft, 4ft, and 8ft lengths. The SS-SP05 series offers all three to match different ceiling heights and application needs.
Size
Best Ceiling Height
Typical Application
2ft
8-12 ft
Narrow aisles, under-shelf
4ft
10-16 ft
Standard commercial
8ft
14-20 ft
Warehouse, industrial
7. How many LED strip lights do I need?
Calculate based on desired foot-candles (FC) and room size:
Warehouses: 20-30 FC, 8ft spacing for 4ft fixtures at 14ft ceiling
Retail: 30-50 FC, 6ft spacing for 4ft fixtures at 12ft ceiling
Offices: 30-50 FC, 8ft spacing for 4ft fixtures at 9ft ceiling
8. What color temperature should I choose?
Match color temperature to your application:
3500K (Warm White) – Retail, hospitality, healthcare waiting areas
4000K (Neutral White) – Offices, schools, general commercial
5000K (Daylight) – Warehouses, industrial, garages, outdoor areas
9. What’s the difference between 2ft, 4ft, and 8ft LED strips?
The main difference is coverage area and recommended ceiling height. 2ft covers approximately 4×4ft area at 10ft ceiling. 4ft covers 6×6ft area at 14ft ceiling. 8ft covers 8×8ft area at 18ft ceiling.
10. Can I use 8ft strips in a 4ft grid ceiling?
Not directly. 4ft grid ceilings require 4ft fixtures. However, you can mount 8ft strips perpendicular to the grid, or use suspended mounting that bypasses the grid entirely.
⚡ Installation & Electrical
11. How do I install LED linear strip lights?
Three mounting options:
Surface mount: Screw brackets to ceiling, snap fixture in place
Suspended: Hang with chains or cables from ceiling
Wall mount: Attach vertically for cove or perimeter lighting
12. Do LED strip lights need a ballast?
No. LED strips use built-in LED drivers. Never connect LED fixtures to existing fluorescent ballasts—this will damage the LEDs and void the warranty.
13. What voltage do LED strip lights use?
Most commercial LED strips accept AC120-277V input, covering standard 120V and 277V commercial circuits. Always verify voltage compatibility before installation.
14. Can LED strip lights be dimmed?
Yes, if equipped with 0-10V dimming. The SS-SP05 series includes 0-10V dimming as standard, compatible with most commercial dimmers and lighting control systems.
15. How do I wire 0-10V dimming?
0-10V dimming requires two additional wires (typically purple and gray) connected to a compatible dimmer or control system. These wires carry the dimming signal separate from power.
💡 Performance & Efficiency
16. How much energy do LED strip lights save?
LED strips typically save 40-60% compared to fluorescent equivalents. A 40W LED strip produces similar light to a 40W fluorescent tube plus ballast, but at lower actual wattage when using selectable settings.
17. What is LM/W efficacy?
Lumens per watt (LM/W) measures how efficiently a fixture converts electricity to light. Higher is better. The SS-SP05 series delivers 130-150 LM/W, compared to 80-100 LM/W for typical fluorescent systems.
18. Do LED strip lights produce heat?
LEDs produce less heat than fluorescent or incandescent lighting, but they still generate some heat. Quality fixtures include aluminum heat sinks to dissipate heat and extend LED life.
19. Can LED strip lights be used in cold environments?
Yes. Unlike fluorescent tubes that struggle to start in cold temperatures, LEDs perform well in cold environments. They’re actually more efficient in cooler temperatures.
20. What is CRI and why does it matter?
Color Rendering Index (CRI) measures how accurately a light source reveals colors. CRI >80 is standard for commercial applications. Higher CRI (>90) is preferred for retail, art galleries, and color-critical work.
