Length=Number of LEDs PSU = Number of LEDs × 12mA Example: Out1 with 72 LEDs → Length=72；PSU = 72 × 12 = 864mA Out2 with 36 LEDs → Length=72；PSU = 72 × 12 = 432mA Set WLED Parameters In WLED channel settings: Set max. mA/LED to 51mA Set PSU to your calculated value (e.g., 864mA / 432mA) Type B(for Govee permanent outdoor Lights Pro) Calculate PSU Value Use 18mA per LED as the base. Length=Number of LEDs PSU = Number of LEDs × 18mA Example: Out1 with 60 LEDs → Length=60；PSU = 60 × 18 = 1080mA Out2 with 30 LEDs → Length=60；PSU = 30 × 18 = 540mA Set WLED Parameters In WLED channel settings: Set max. mA/LED to 110mA Set PSU to your calculated value (e.g., 1080mA / 540mA) Button Button Type Function Button0 Pushbutton Single press: On/Off Button25 Pushbutton • In normal mode: Single press → Cycle through the 144 standard lighting effects. Double press → Switch to Music Mode. • In Music Mode: Single press → Cycle through the 23 music-reactive effects. Double press → Exit Music Mode and return to normal effect selection. How to Connect to WLED Step 1 — Power & LED hookup Based on the variant you purchased, connect the corresponding power supply and light(s) for your model. (Ensure matching voltage, correct polarity, and common GND; data goes to LED DIN.) Step 2: Connect to Device Hotspot Open your phone Settings → Wi-Fi (WLAN). In the available networks list, find the hotspot named WLED-AP. Tap the network to connect. On your phone, connect to WLED-AP with password wled1234 If the portal doesn’t open, browse to http://4.3.2.1 or http://192.168.4.1 step 3: Open Setup Page After connection, wait a few seconds. The WLED Wi-Fi Setup Page will automatically pop up.If it does not appear, open your browser and enter:4.3.2.1 to access the setup page manually. Step 4: Configure Home Wi-Fi On the setup page, you can: Manually enter your home Wi-Fi SSID (name) and password. Or tap Scan to search for nearby Wi-Fi networks, select the one you want, and enter the password. Tap Save, and the controller will reboot and try to connect to your home Wi-Fi network. Alternative: If you don’t want to connect to a router, stay in AP Mode. Simply click To the controls on the portal page. You can control WLED directly over the WLED-AP hotspot. Step 5: Use AP Mode (No Router Needed) If you don’t want to connect to a home Wi-Fi network, you can keep using AP Mode. Open your phone Settings → Wi-Fi, connect to WLED-AP. The default password is:wled1234 With AP Mode, you can control lights directly via the WLED app or the web interface, without an internet connection. Step 6 — Open WLED on your network Reconnect your phone to your home Wi-Fi. Then open wled.local (mDNS-enabled devices) or the IP shown on your router. Step 7 — Control Your Lights Once you have successfully connected to Wi-Fi or accessed the device through AP Mode, the WLED control interface will appear. You can adjust colors, brightness, effects, and presets directly from this page. Alternatively, you can also use the WLED-Native App for control. Download: Search for “wled-native” in the Apple App Store (iOS) or the Google Play Store (Android). Step 8 — First-time LED setup In Config → LED Preferences set: LED Type, Color Order (often GRB), Data Pin, LED Count, and Max Current/Brightness Limiter. Save. No light → recheck polarity, common ground, and DIN direction. For detailed usage, see the official docs: https://kno.wled.ge Open-Source Notice: This product uses WLED (licensed under EUPL-1.2).

FCC 47CFR §2.1091 REQUIREMENT 2.1 TEST STANDARDS The limit for Maximum Permissible Exposure (MPE) specified in FCC 1.1310 is followed. The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 2.2 LIMIT According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of the human exposure to radio-frequency (RF) radiation as specified in 1.1307 (b) Limits for Maximum Permissible Exposure (MPE) Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm²) Limits for Occupational / controlled Exposures 300 - 1500 -- -- F/300 3.0-30 1842/f 4.89/f *(900/f²) 1500 – 100000 -- -- 5.0 Limits for General population / Uncontrolled Exposure 300 - 1500 -- -- F/1500 1.34-30 824/f 2.19/f *(180f²) 1500 – 100000 -- -- 1.0 F= Frequency in MHz Friss Formula Friss Transmission Formula: Pd = (Pout * G) / (4*pi*r²) Where Pd = power density in mW/cm² Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = Distance between observation point and the center of radiator in cm If we know the maximum gain of the antenna and the total output power to the antenna, t…
