2BTW8-SLS1Smart Solar Spotlight

1 User manual Of Eluntrix Solar Landscape Spotlight SLS1 IMPORTANT TIPS  Control Method: The light must be connected to the App for control and normal operation.  Energy-Saving Mode: After connecting to the app, the light enters Energy- Saving Mode by default, automatically adjusting brightness based on the battery level: the lower the battery level, the lower the brightness. If you prefer the light to remain at 100% brightness or any fixed brightness level, please disable Energy-Saving Mode in the App. Once disabled, the light will operate continuously at the brightness level you set.  Runtime: If the light’s runtime is shorter than expected, it may be caused by insufficient charging due to inadequate sunlight. In this case, lowering the brightness is recommended to extend the lighting duration.  Installation Location: To ensure optimal charging duration and better overall performance, install the light in a location with abundant sunlight, keeping the solar panel unshaded and fully exposed to direct sunlight.  First-Time Use: For best performance, it is recommended to charge the light continuously for 48 hours before the first use. Introduction Our smart solar spotlight features an easy, wire-free installation with a plug-and-play solar-powered design. The adjustable angles allow for flexible illumination. The light automatically detects ambient lighting—turning on at night and off at dawn. Smart control can also be achieved through the mobile app. Specifications LED QTY 96 PCS IP rating IP65 Temperature Range 14°F - 104°F (-10∞C - 40∞C) Materials ABS body + PC lens Beam Angle 90∞ Colors Warm White + Cold White + RGB 2 Installation Method 1: Wall-Mounted Installation STEP 1: Insert the ground stake vertically into the soil and ensure it is firmly secured. STEP 2: Attach the light to the ground stake using the mounting pole of the light, then adjust the lighting angle (ensure it can receive adequate sunlight). After adjustment, tighten the locking screw on the mounting pole. (Note: do not press the light with your hands to force it into the ground, as this may damage the fixture. Secure the ground stake firmly first, then gently insert the light into the stake using the mounting pole.) STEP 1 STEP 2 Method 2: Wall-Mounted Installation Step 1: If installing on a hard surface such as concrete, drill two holes first and insert the wall anchors. (If installing on softer materials like wood, this step can be skipped.) Step 2: Use screws to secure the mounting pole to the drilled positions. Step 3: Hand-tighten the screws to attach the light to the mounting pole. Step 4: Adjust the lighting angle as needed, then tighten the fixture to lock it in place. Step 1 Step 2 Step 3 Step 4 3 Download and Connect the App 1. Scan the QR code below to download the App, or search for SmartLife in the App Store or Google Play. 2. Open the App and log in or create a new account. 3. Enable Bluetooth on your phone. 4. Pair Mode: Turn on the light using the power switch. The light will enter pairing mode immediately: it will flash for 3 seconds and then remain on at low brightness for up to 10 minutes. If pairing is not completed within 10 minutes, pairing mode will end and the light will switch to steady high brightness. To re-enter pairing mode, toggle the power switch 6 times consecutively (OFF–ON–OFF–ON–OFF–ON). 5. Tap the “+” button in the App and select “Add Device” to add the light to the App. 4 6. When no obstructions, the control range of the light can reach up to 98 ft (30 m). Using the App for Control and Settings 1. You can check the battery level in the App. 2. Energy-Saving Mode： The solar light is set to Energy Saving Mode by default, as follows: 70%–100% battery: 100% brightness 50%–70% battery: 90% brightness 20%–50% battery: 70% brightness Below 20% battery: 10% brightness If you prefer the light to run at 100% brightness or any other fixed brightness level, please disable Energy Saving Mode in the App, as shown below. Once disabled, the light will operate at the brightness level you set. 3. You can adjust the brightness as needed. 5 (Note: If the lighting duration is insufficient, it is recommended to lower the brightness.) 4. Color Selection: Tap the “Colour” icon to select colors such as Red, Green, and Blue. Tap the “White” icon to select white light, with any color temperature between 3000K and 6500K. 5. Scenes Selection: Tap the icon below to choose different light effects and themes. 6 6. Music Sync: You can Sync lights with music in section below. 7. Auto On and Off: You can use the button below to enable or disable the “Solar Energy” feature. When enabled, the light will automatically detect ambient light— turning on at night and turning off at dawn. 7 8. Schedule: You can set the light to turn on or off automatically at any desired time, as shown in the images below. Please note that the scheduled on/off time may experience a tolerance of about 30 seconds.” 9. Create Group: You can add multiple lights to a group. You can control all lights in the group together and use all functions simultaneously, except scheduling. Schedules must be set individually for each light. Tap the edit icon in the upper-right corner of the App, then select “Create Group” in the pop-up window to set up a group. 8 Restoring to factory settings & Re-Pairing the light During later use, if you need to re-pair the light, or if the light has already been paired with one mobile phone and you would like to install the app and connect the light on a different phone, you must first restore the light to factory settings. Follow the steps below: 1. If the previously installed App is still accessible, you can remove the light from the device list in the app’s Device Management page, as shown below: 2. Toggle the light’s power switch consecutively to restore to factory setting. If the power switch is in the ON position, toggle the switch six times consecutively (OFF–ON–OFF–ON–OFF–ON) to restore the light to factory …
