Non-alcoholic fatty liver disease (NAFLD) is the build up of extra fat in liver cells that is not caused by alcohol. It is normal for the liver to contain some fat. However, if more than 5% â 10% percent of the liverâs weight is fat, then it is called a fatty liver (steatosis).
There are two main types of energy efficient light bulbs available in the UK. Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs). CFLs are a cost-effective option for most general lighting requirements. Replacing a traditional light bulb with a CFL of the same brightness will save you about Â£5 per year, or Â£70 over the lifetime of the bulb.
A fluorescent lamp converts electrical energy into useful light much more efficiently than incandescent lamps. The typical luminous efficacy of fluorescent lighting systems is 50â100 lumens per watt, several times the efficacy of incandescent bulbs with comparable light output. fluorescent lamp or a fluorescent tube is a low pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the bulb to glow.
