Ways for choosing Light Bulb
Many kinds of lighting options exist. Learn how your everyday life is influenced by lighting, the various types of light bulbs, and which bulbs can create the perfect lighting for your home.
Your best choice for light bulb
Tons of options exist for the purchase of light bulbs, but it is not difficult to choose the right kind. The light bulbs today are mainly light-emitting diodes (LED). LED bulbs are the most energy efficient option for standard light sockets. LEDs have less wattage, but emit the same LEDs as incandescent bulbs. This allows the same amount of light to be produced, but less energy is needed. Mercury cannot and cannot be contained in LEDs for more than 20 years.
LEDs are used to illuminate the small diodes by using a semi-conductor electrical current. The heat is consumed in a heat sink, which keeps the bulbs cool. It also does not contribute to the build-up of heat, which helps to save air conditioning. LEDs can also be used externally — just check the packaging for an outdoor rating.
Lumens and Watts
For light production and energy utilisation, lumens and watts are essential.
Lumens: The quantity of light from the lamp. More lumens are the same as brighter light; less lumens are the same. Normal 100 watt bulbs make approximately 1600 lumens.
Watts: A light bulb uses sum of electricity. The lower the wattage of the light bulb, the lower it. Compact fluorescent lamps (CFLs) and LEDs are less than incandescent bulbs with the same output of light.
Light colour or presence is determined on the temperature scale of Kelvin (K), and this varies from light bulbs in soft white. Lower numbers of kelvin are more yellow; higher is the amount of kelvin, whiter or bluer is the sun.
- The standard colours of incandescent bulbs are the soft white (yellowish range) 2700K to 3000K. Great for bedrooms, dens or dining rooms and dark wooded features.
- Warm White 3000K to 4000K: Ideal for kitchens, workspace and bathrooms (Between Yellowish and White Ranges).
- Bright White (Between the White and Blue Strings) 4000K to 5000K: these bulbs, such as GE Reveal bulbs, are best used in chrome- or white-mounted kitchens and bathrooms.
- 5000K to 6500K Daylight: ideal for reading, because the eyes are simple and light lighting.
The industry standard used to be incandescent bulbs, but new energy efficiency requirements for simple bulbs are now mandated by law. The regular incandescent bulbs of 100, 75, 60 and 40 watts have all been phased out and no longer made. There will also be a variety of special incandescent bulbs, such as lighter bulbs. Incandescent bulbs use the heated filament to glow. The light bulb is created by the glowing filament.
Fluorescent bulbs or tubes are filled with mercury vapour which when power is applied, emits ultraviolet (UV) light. The light bulbs/tubes have a layer inside which makes ultraviolet rays visible. They use less energy than a lamp and are suitable for offices, kitchens, corridors and other places that require a wide light area. Fluorescent bulbs often contain about 75 percent lower temperatures than incandescent bulbs.
