1. What is Flexible LED Strip Light?
Flexible LED strip light is a versatile lighting fixture made from a flexible PCB board populated with SMD LEDs, resistors, and electronic components. It bends to fit curved surfaces and can be connected in long lengths.
- Flexible PCB — bends around corners and curves
- 3M adhesive backing — peel and stick installation
- Cuttable at designated points
- Available in DC12V, DC24V, and AC220V
- Waterproof options: IP65, IP67
Beyond LED strips, Lightstec supplies Mean Well drivers, connectors, wires, dimmers, RGB/RGBW controllers, aluminium profielen, linear lights, panel lights, floodlights, and sensors.
2. Where Are LED Strip Lights Used?
LED strip lights are limited only by your design creativity. They are used across residential, commercial, and industrial settings:
For DIY enthusiasts, installing strips under kitchen cabinets is one of the most popular projects — easy to install with impressive results. Waterproof versions (IP65 for moist areas, IP67 for outdoor) expand possibilities further.
3. What is Color Changing LED Strip Light?
Color changing strips use a controller to produce any color. There are four main types:
Each LED has red, green, and blue chips. Mixes to create any color, including white. Controlled via RGB-controller.
Combines RGB LEDs with dedicated white LEDs for accurate white output. Available in RGB+Warm White, RGB+Natural White, RGB+Cool White.
Single LED package contains R, G, B, and white chips for seamless color mixing in a smaller footprint.
Each LED is individually addressable (WS2811/SK6812). Enables chasing effects, animations, and pixel-level control.
4. How Many Brightness Levels Can I Choose?
Brightness is determined by wattage per meter. All LED types deliver roughly 100–150 lumens per watt. Available LED types include SMD3528, SMD5050, SMD2835, SMD3014, SMD2216, SMD335, SMD5630, and SMD3030.
| LED-dichtheid | Typical Wattage | Beste voor |
|---|---|---|
| 30 LED's/m | 2.4–4.8W/m | Accent lighting, low-brightness needs |
| 60 LED's/m | 4.8–14.4W/m | Most popular — general purpose |
| 120 LED's/m | 9.6–24W/m | High brightness, uniform light |
| 240 LEDs/m | 19.2–28.8W/m | Dot-free, commercial grade |
| 300 LEDs/m | 24W/m+ | Maximum brightness, linear effect |
5. LED Strip Brightness by Wattage
| Model | Wattage | Helderheid | Beste voor |
|---|---|---|---|
| SMD3528-60LED/m | 4.8W/m | ~480 lm/m | Cabinet, display box, car interior |
| SMD5050-60LED/m | 14.4W/m | ~1200 lm/m | Most popular, RGB available, 3x brighter than 3528 |
| SMD2835-120LED/m | 12W/m | ~1200 lm/m | High efficiency, good heat management |
| SMD5050-240LED/m | 24W/m | ~2400 lm/m | High brightness, needs aluminum profile |
Note: Strips over 20W/m require aluminum profiles for proper heat dissipation.
6. How Wide Are LED Strip Lights?
Lightstec offers standard PCB widths and custom sizes up to 250mm:
The width depends on your application and the matching aluminum profile. Aluminum PCB strips are typically wider than flexible strips. Custom widths are available for project orders.
7. How Long Per Reel?
Voltage drop guide: DC12V strips — max 5m per power feed. DC24V strips — max 10m (2 reels) per feed. For hotel projects with identical rooms, we pre-cut all strips to spec and pair with matching Mean Well drivers.
8. Do You Offer Aluminum Profiles?
Yes. Aluminum profiles improve aesthetics (professional finish) and provide critical warmteafvoer, extending the lifespan of high-wattage strips.

9. Can I Cut LED Strip Lights Myself?
- Locate the copper cutting marks on the PCB
- Cut with sharp scissors along the marked line
- Use solderless connectors or solder to join sections
- Verify connections before final mounting
Pro tip: For permanent installations, soldering is more reliable than connectors. If a section doesn’t light up, double-check the cut point.
10. What Colors Are Available?
Single colors:
White colors by CCT:
| CCT Range | Beschrijving | Common Use |
|---|---|---|
| 2100K–2700K | Warm White | Cozy home, bedroom, restaurant |
| 3000K–3500K | Soft White | Living room, hotel, retail |
| 4000K–4500K | Natuurlijk wit | Office, showroom, kitchen |
| 5500K–6500K | Koel wit | Warehouse, hospital, task lighting |
| 7500K–10000K | Daylight+ | Specialty, high-contrast applications |
Color changing: RGB, RGB+Warm White, RGB+Natural White, RGB+Cool White. Custom CCT matching available — send us a sample.
11. What CRI Is Available?
| CRI-niveau | Status | Beste voor |
|---|---|---|
| CRI >70 | Being phased out | Basic, cost-sensitive projects |
| CRI >80 | Standard (default) | General commercial and residential |
| CRI >90 | Growing demand | High-end retail, art gallery, photography |
CRI (Color Rendering Index) measures how accurately a light source reveals colors compared to natural light. Higher CRI = more accurate colors.
12. Is LED Strip Light Easy to Install?
- Connect LED strip to the power supply
- Plug power supply into AC mains (110V/220V)
- Peel 3M adhesive backing and stick in place
We supply everything you need: power supplies, controllers, dimmers, connectors, and wires — one-stop sourcing from a single factory.
13. Do You Have Waterproof Versions?
| IP-classificatie | Bescherming | Construction | Beste voor |
|---|---|---|---|
| IP20/IP33 | None | Bare PCB | Indoor, with aluminum profile |
| IP55 | Moisture | Silicone glue coating | Bathroom, kitchen (indoor moist) |
| IP65 | Dust + rain | Silicone tube | Outdoor covered areas, popular choice |
| IP67 | Submersion | Fully sealed silicone tube | Pools, fountains, extreme outdoor |
14. SMD3528 vs SMD5050
| Specificatie | SMD3528 | SMD5050 |
|---|---|---|

16. Are LED Strip Lights Dimmable?
Yes. Three dimming methods are available:
AC220V → Power Supply → Dimmable Controller → LED Strip. Simple, cost-effective, works with any strip.
AC220V → Triac Driver → LED Strip. Replace standard driver with triac driver; use standard wall dimmer.
For commercial and smart-home integration. Compatible with building management systems.
17. How Do I Install LED Strip Lights?
- Driver wattage = 20% higher than total strip wattage
- Driver output must match strip voltage (12V/24V)
- Adheres to metal, wood, plastic, stone (smooth/clean)
- Not for oily, rough, or powdery surfaces
For strips over 20W/m, always use aluminum profiles or metal channels for heat dissipation.
18. Are There Different Quality Grades?
The market has many quality grades at varying prices. Lightstec primarily serves engineering and project clients, so we maintain high standards:
Our LEDs pass LM-80 lifetime testing, ensuring long-term lumen maintenance.
