The Energy-Saving Light Bulbs That Could Leave You Red-Faced; UV Rays: One of the BulbsByline: Daniel MartinDaily Mail (London)
Many indoor offices and businesses use halogen and fluorescent light bulbs. Copy machines also have lighting mechanisms that emit UV rays that can cause lupus symptoms. Fortunately, there are shades, shields, filters, and tube covers available through several manufacturers that can offer protection fro...
You may have heard that you can't get a sunburn through glass, but that doesn't mean glass blocks all ultraviolet, or UV, light. The rays that lead to skin or eye damage still can get through, even if you don't get burned. Types of Ultraviolet Light The termsultraviolet lightandUVre...
UV light bulbs designed to emit ultraviolet radiation in the UVC range, specifically at 254 nm, are proven to provide high germicidal efficacy in many disinfection applications for surfaces, water, andair purification systems. UVC light emitted by the sun is fully absorbed by the ozone layer and...
100 lumens per watt at the expense of 350 milli ampere current. Energy loss through heat is practically nil in LEDs and they have very long life of thousands of hours. LEDs are eco friendly devices since they contain no lead or mercury. Unlike fluorescent lamps, LEDs do not emit UV rays...

Warm incandescent light bulbs, which emit a warmer light that produces fewer UV rays than their bright white counterparts. Full spectrum lighting, which is basically a marketing term that refers to bulbs that simulate natural sunlight and provide a balance of brightness and contrast. LED bulbs,...
LED stands for light-emitting diode, and LEDs are basically innovative bulbs that emit certain light currents in a safe and efficient way. LEDs can come in a range of colours, and the various colours have different effects. This is why Light Therapy is becoming so popular in the health ...
Blue light is one of the colours that can be perceived by the human eye along the visible light spectrum; it is located near violet at the high-energy end. Exposure to large amounts of high-energy light, such as invisible ultraviolet (UV) rays, has a higher potential to cause retinal ...
