Basic Knowledge of LED Downlight and Tube Lights

Service Life of LED Downlight

Since LED downlight uses the solid light source luminous, so its life mainly depends on the solid-state LED light source and drive cooling part. At present, the LED downlight service life has reached more than 100,000 hours, with a large number of popular LED technology continues to evolve, and the application of technology in the drive and cooling basically achieve the ideal state, a commercially available high-quality LED downlight life basically reaches 10000-50000 hours, almost 10-50 times of the ordinary halogen downlights. LED downlight products save up 80% energy, it is almost maintenance-free. There is no problem of frequent replacement parts. Within six month, users can take back the cost. At present, led downlight is mainly used in the commercial industry. Since the price is too high that not every family can afford it. It is made of the green-semiconductor light source, and the light is soft, pure spectrum, eyesight protection and good health.

LED Downligh Price

Since the LED bulb halogen downlight is more complex in structure than the common lights. So even in the case of large-scale production, the price will be higher than common halogen lamps. With more and more people understand and accept, and the scale of production slowly spreads the LED downlight price will soon reach the acceptable level. If you buy it, when you count the sum of energy-saving account, you will find even higher price in one year based on the electricity bills of the initial purchase cost plus one, and the annul cost should lower than traditional halogen lights. Currently, the service life of the LED downlight can be up to 30,000 hours.

Energy-saving Effect of Ceiling Tube Lights

LED ceiling tube lights has the same caliber with traditional fluorescent lamp, the lengths are 60cm and 120cm and 150cm three kinds. The power has different types such as 8W, 9W, 10W, 12W, 15W, 16W, 20W and 18W. The actual power consumption of traditional fluorescent (inductive ballast device) is about 26W and 36W. The ceiling tube lights are much energy-saving than the traditional 40W fluorescent lamp. And it is much brighter. The 8W LED ceiling tube light have been brighter than traditional 64W fluorescent lamp, LED LED ceiling tube light in particular, appear to be more gentle and more practical, making it easy to access the grant. The life of the supply voltage is 50000 to 80000 hours AC85V-260V (AC), without starter and ballast, quick start, low power, no stroboscopic, eye fatigue is not easy. It is not only super energy saving is more environmentally friendly. National green energy-efficient lighting project focuses on the development of one of the products, to replace the traditional fluorescent products.
