Brief Introduction: Smart and energy saving YY104 Solar PIR Sensor LED Light - Automatic switching on when detecting people coming and automatic power off when detecting people left， automatically charge its batteries by the solar panel during the sunny day ( more than 100Lux ) and in the night ( less than 10Lux ) uses it for illumination. It works up to a 90 degree angle and detects motion up to 5 meters away. With solar panel， can convert solar energy into electricity， no need of outside power， energy efficiency and environmental protection. IP44 waterproof grade， perfect for garden， eave， gutter， courtyard， balcony， etc. Simple fashion design， it is not only a Motion Sensor Solar Lamp， but also an adornment. Technology creates happy life!Specifications: Sensor sensitivity distance / angle: 5m / 90 degreeSolar panel power: 0.8W 2VSolar panel size: 7.7 x 7.7cm ( L x W )Built-in battery: 3.7V 75mAh rechargeable batteryLED: 4 pieces SMD 5730 white light LED， 15LmLED power: 0.5W / LEDDelay time: 37 secondsInduction time: Max. 30 times per night Charging time / Working time: 4.5 hours / 8 - 12 hours Category: LED Outdoor Lights Style: Modern， LED Suggested Space Fit: Garage， Entry， Pathway， Outdoor， Garde Number of Lights: 4 SMD 5730 LEDs LED Color: White Lighting Direction: Downlight Features: Sensor Materials: Plastic Power Supply: Solar Powered Color: White Package weight: 0.248 kg Product size (L x W x H): 12 x 12 x 5 cm / 4.72 x 4.72 x 1.97 inches Package size (L x W x H) : 13 x 13 x 7 cm / 5.11 x 5.11 x 2.75 inches Package Contents: 1 x YY104 Solar Light Motion Sensor 4 SMD 5370 LEDs IP44 Water Resistant Garden Gutter Lamp， 4 x Screw， 2 x Screw Sleeve， 1 x Pin Key， 1 x Expanding Bolt IPXX Rating ChartIP Code The IP Code (or International Protection Rating， sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529， it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers)， dust， accidental contact， and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof. The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. For example， an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or 2X are typical minimum requirements for the design of electrical accessories for indoor use.
