1.Intelligent Control And Patented Technology
(1) Self-developed controller: adapted to the exclusive GOULY APP (iOS/Android), realizes remote color mixing (16 million colors), dynamic mode switching (gradient, breathing, music rhythm), and supports voice control (compatible with Amazon Alexa, Google Assistant).
(2) Three-chip independent driver: each hemisphere of the LED light string is built-in 3 SM16703 chips for more stable signal transmission, avoiding the problem of uneven color due to voltage attenuation of long-distance LED light string, ensuring the consistency of the effect of large-scale decorative projects (such as architectural contour lighting).

2.Extreme Durability LED Light String And High Brightness Durable Light Source
(1) Extreme temperature tolerance: the operating temperature range of -40 ℃ ~ +60 ℃, to adapt to the cold of northern Europe and southern Europe heat, fearless climate challenges.
(2)IP67 full protection: dustproof and waterproof, can be immersed for a short period of time, easy to cope with the rainy and humid outdoor environment in Europe.
(3)SMD5050 LED chip: 18 high-density LEDs per meter, with 180° wide-angle light emission, even and soft light, high color saturation.
(4) Ultra-long life: 100,000 hours of service life, reducing maintenance costs.
(5) Ultra-low power consumption (0.72W): more than 80% energy saving compared with traditional decorative lights.


3.Flexible Installation And Safety Design
(1) Cutting Copper Point Segmentation: Each meter of LED light string is preset with 6 segments (each segment contains 3 LEDs), which can be cut to any length as needed for quick expansion or partial replacement, and the copper soldering point ensures that it can still be energized and used after cutting.
(2) PC hemisphere lampshade: diameter 43mm, high transmittance and impact resistance, anti-ultraviolet aging.
(3) Silicone Strip: soft and bendable, high temperature resistant, tear resistant, supports winding or attaching to complex surfaces.
(4) 12V low voltage power supply: no risk of electric shock, in line with European safety norms for homes and public places.

4.LED Light String Scenario-based Application Advantages
(1) Commercial and municipal projects:
1.High brightness illusion effect (18LED/m): to meet the eye-catching needs of European holiday bazaars (such as Christmas lights), commercial landmarks (hotel facades, plaza sculptures).
2.Waterproof and weatherproof: suitable for fountains, swimming pools around the wet area decoration, expanding the market of high-end hotels and resorts.
(2) Home scenes:
1. Low-voltage safety (12V): applicable to children's rooms, garden walkways and other family areas.
2. APP mode: switch the mode of"holiday party" and"cozy night light"with one key.
5.Packaging And Warranty
(1) Standard package: 5 meters/roll (including controller, waterproof connector), support OEM length customization.
(2)Warranty: 3 years,CE & RoHS certification is complete.
6.LED light string installation precautions
(1) Power supply and circuit safety:
The use of 12V DC power adapter in line with the European Union CE certification (direct access to 220V AC power is strictly prohibited), the maximum load of a single LED light string does not exceed 5 meters.
(2) Waterproof treatment:
1.After cutting the LED light string, we must use the matching waterproof plug + silicone sealing sleeve to wrap the exposed copper points, and use heat-shrinkable tubing for secondary reinforcement.
2.Avoid immersing the LED light string in flowing water or strong pressure water column for a long time.
(3) LED light string cutting and splicing:
1.Cutting is only allowed at the preset copper point marking (about 16.6cm between each segment).
2.When connecting multiple sections of LED light string, use tinned copper wire soldering or special waterproof connectors.
(4) LED light string mounting and fixing method:
It is recommended to use UV weather-resistant double-sided tape (3M VHB series) or nylon cable ties to fix the LED light string, and the bending radius of the LED light string should be ≥5cm.
(5) Extreme temperature environment precautions
1.Low temperature installation (-40 ℃ ~ 0 ℃): Before installation, leave the LED light string at room temperature (≥ 10 ℃) for 1 hour, and then adjust the brightness and color after the installation after 10 minutes of power preheating.
2.High-temperature environment (>45℃): Avoid LED light string close to dark-colored heat-absorbing surfaces (e.g., asphalt, metal plate), and prohibit prolonged high-brightness operation on the surfaces of flammable materials (e.g., hay, wooden decorations).
(6) Intelligent controller use tips
1.The distance between the controller and the LED light string is ≤ 10 meters, and a signal booster should be added if it is too far away (the model should match SM16703 IC).
2.When connecting for the first time, make sure that the distance between the Bluetooth/WiFi of your cell phone and the controller is <3 meters, and close the interference of other smart devices around.
