rigid led bar, aluminum led bar led strip: Description:This LED light bar is designed for indoor lighting, there are 42pcs high intensity SMD 5050 on 50cm long aluminum PCB board, working voltage 24V dc. Due to smart size, it can be mounted to any places, and3M tape back of the PCB board for simple installation.Spe:1. PCB: aluminum PCB which will help the heat emitting from the leds go to air faster and easier, and will slow down the speed of the luminous decay (led brightness decay speed);2. Dimension: 500 x 12 x 2MM (Height x Width x Height/thickness)3. Light source: 5050 SMD led (3chips in 1LED)4. LED qty: 42pcs5. LED bar brightness: 650 700lm ( grade A LED: top quality 2700 7000K) 500 600lm ( grade B LED: middle quality 2700 7000K)6. Lumen/brightness decay speed: less than 3% in 1000 hours (grade A LED) less than 5% in 1000 hours (gradeB LED)7. Cuttable length: every 6leds cuttable8. Working voltage: 24V dc9. Power consumption: around 8.5W, Max. 9W10. light angle: 120 deg11. LED color: white, warm white, red, yellow, green, blue, pink...all single colors12. Life time: around 50,000 hoursApplication:1) back light of light box;2) decorative lights of stores, rooms, hotels, restaurant...Warning:1. the working voltage of the light bar is 24V dc, not 12V dc, pls noted;2. the light bar are designed for indoor, not outdoor
