what are Lumens and why are they the most commonly used unit of measurement for lighting product?  there's only a lot of different ways to measure visible light out there depending on the product and the application and contrary to popular lumen opinion exactly the best measurement for the Emergency warning Market before we get a better understanding of                         what part of the electromagnetic spectrum?  the Spectrum begins with super long radio waves measuring the size of Mount Everest to super tiny gamma rays still larger than Atomic nuclei the section between infrared and ultraviolet light is known to us as visible light wavelength for higher power now that we understand what we can and can't see  let's learn a little more about a human eye sensitivity believe it or not the human eye doesn't react the same to all colors on the Spectrum when looking at the visible light spectrum you will notice that are high is the most sensitive at about

 What is the high power led? High power LED refers to the light-emitting diode with a large working power rating. Ordinary LED power is generally 0.05W, and the working current is 20mA, while high power LED can reach 1W, 2W, or even dozens of watts like 50w 100w, and the working current can range from dozens to hundreds of milliamps. Due to the current constraints of high power LED in terms of light flux, High lumins for watt, conversion efficiency and cost, the application of high power white LED in the short term is mainly the lighting in some special fields, while the long-term goal is general lighting. Can find in various colours What kind of led high power chips you can find in market and what is the price? here is the list of top 10 led brands you can find 1.Epi LED 2.Cree LED 3.Osram LED 4.Nikia 5.Luxeon 6.LG 7.Samgsung 8Lumi LED 9. Vishay 10.Philips

Guide lines to buy good quality light Power consumptio pin type lumens lumens per watt  brand cost  What is Power consumption  ? In  electrical engineering ,  power consumption  refers to the  electrical energy  per unit  time ,  supplied to operate something, such as a  home appliance . Power consumption is usually measured in units of watts (W) or kilowatts (kW). when you buy a led light to your home you may need small led like 7w to 20w Pin Type E27  LED Bulbs  (ES) E14  LED Bulbs  (SES) B22  LED Bulbs  (Bayonet) B15  LED Bulbs  (Small Bayonet) GU10  LED Bulbs . G4  LED Bulbs . G9  LED Bulbs . MR16  LED Bulbs Lumens Lumen is how much light is produced by the led so with new high power led 1w it will be make about 100lm from the edison led it can be like 10w lumens per watt this is the imported thing when you are buying the led for exampe with epi lumen for watt is 100 cree lumen for watt is  150 so if the new cree led is doubled lumins you can use 2w

Lets check what is the UV led   Ultraviolet  ( UV ) is  electromagnetic radiation  with  wavelength  from 10  nm  (with a corresponding frequency of approximately 30 PHz) to 400 nm (750 THz), shorter than that of  visible light  but longer than  X-rays . UV radiation is present in  sunlight , and constitutes about 10% of the total electromagnetic radiation output from the Sun Can LED UV killes the corona virus? As the serches on internet led UV can not remove the corona virus but it can remove  some of the bactirias and viruses  so lets check some videos how this thing is going to work In this video talk about LED UVC. this led uvc light is wave lenth of 100nm to 280nm What can you do with the uv leds 1  Tanning and skin treatment 2  Fluorescent inspection 3  Disinfection and germ control 4  Air Cleaning and bug eradication 5  Indoor Gardening . 6 Detect money 7Gel manicures
