3. Тохиргоо ба суурилуулалт
These bulbs are designed for simple installation into compatible fixtures. Follow these steps:
- Унтраах: Суулгахын өмнө цахилгаан цочролоос сэргийлэхийн тулд гэрлийн төхөөрөмжийг таслуур дээр унтраасан эсэхийг шалгаарай.
- Хуучин чийдэнг арилгах: Carefully unscrew and remove the existing bulb from the fixture.
- Шинэ чийдэнг суулгах: Screw the Lepro Dusk to Dawn LED bulb into the E26 medium screw base socket until it is snug. Do not overtighten.
- Эрчим хүчийг сэргээх: Хэлхээ таслагч дээр цахилгааныг дахин асаана уу.
- Мэдрэгчийн байршил: For optimal performance, ensure the bulb's light sensor is not obstructed by the fixture housing or other objects. The sensor needs direct exposure to ambient light to function correctly. Avoid installing in fixtures that are fully enclosed or have opaque covers that block light from reaching the sensor.

4. Үйл ажиллагаа
The Lepro Dusk to Dawn Light Bulbs operate automatically using integrated photocell sensors. Once installed and powered, the bulbs will:
- Асаах: When the ambient light level drops below approximately 15 lux (typically at dusk), the bulbs will automatically illuminate.
- Унтраах: When the ambient light level rises above approximately 65 lux (typically at dawn), the bulbs will automatically switch off.
No manual intervention or external timers are required for their basic operation. Ensure the sensor is not exposed to direct artificial light sources at night, as this may cause the bulb to turn off prematurely.
