DIFFERENCE BETWEEN LED WARM LIGHT AND DAYLIGHT FULL

Cathodes at each end of the inside of the tube, which generate the electric arc.

Metal contact pins at the outside end of the tube, which provide the electrical connection.

A glass tube (straight, U-shaped or circular).

The basic components of a fluorescent lamp include: Fluorescent lamps require a ballast in order to operate, as well as special lamp holders. The glowing phosphors create white-colored light. Mercury in the gas emits ultraviolet radiation causing the phosphor coating of the lamp to glow, or fluoresce. The efficacy of incandescent bulbs is low which is a major disadvantage in terms of higher operating costs and more heat in the room.ДЇluorescnet Lamps generate light when an electric arc excites the gas in the tube. Most non-reflectorized lamps are the conventional type, most reflectorized lamps today are halogen. Non-reflectorized or reflectorized, according to whether the lamp emits light in all directions or directs light into a beam. Both types are available as conventional and halogen. Line voltage or low voltage, according to the electric current that powers the lamp. Incandescent lamps can be categorized as conventional or halogen, according to the fill gas and pressure in the lamp, which affect efficiency, life and color.

A base to hold the other parts, mount the lamp, and make electrical contact.

An exhaust tube to empty air from the envelope and fill it with gas.

Lead-in wires to bring current to the filament.

A filament of tungsten wire, in a tight spiral.Lamps with the same base can often be used interchangeably in the same fixture (size and wattage permitting). When the filament loses enough tungsten (or breaks from shock), the lamp fails. As the lamp continues to operate, the tungsten slowly evaporates due to the heat. An incandescent lamp generates light when electric current heats a tungsten filament wire so that it glows, or incandesces.

Heidi Wachter has been writing about health, climate change, and the environment for a decade.When finalizing your outdoor lighting or pendant selections, it's important to figure out what type of lamp you'd like to go with. LEDS are more efficient than older bulb types so choose the brightness for your space based on its lumens. Lumens:В Lumens indicate how bright a bulb is while watts indicate the amount of energy use to power it. So, if youвЂ™re using an LED in your art room, for example, consider one with a high CRI. Reds will appear red and blues will appear blues under lights with high CRI. The Label:В LED packaging is required to include information about brightness, light color, energy use, estimated energy costs, and expected life.Д¬olor:В The Color Rendering Index (CRI) is the measurement of how well a source of light renders color. 'Daylight' LEDs may have 5000 K, but also tend to be on the bluer side of the spectrum. Warm yellow light is around 2700 K, while bright white lights are about 3000 K. What to Look for in LED Light BulbsД¬olor Temperature:В The lighting color of LEDs is usually measured in Kelvin (K).

If you have a house full of incandescent bulbs to replace, the Philips 455576 60 watt ( view at Amazon) or GE Lighting 32279 LED Bright Stik ( view at Amazon) are compatible with most lamps and fixtures and wonвЂ™t break the bank. Here are some options that received glowing remarks in our research. That means that they can suppressВ melatonin-a hormone that facilitates sleep-so if you're concerned you may want to consider avoiding very bright LED light tooВ close to bed time, or looking for LED bulbs on the warmer range of the color spectrum. Some LEDs (particularly those used in screens) do emit moreВ blue lightВ than other bulb types. That means youвЂ™ll also save money compared to other bulbs because you wonвЂ™t have to buy them as often, and youвЂ™ll have fewer bulbs to dispose of which makes Mother Earth happy. Most manufacturers promise their bulbs will last 20,000 to 50,000 hours, and offer warranties to back these claims. Switching to LED bulbsВ will reduce your electric billВ and lighten your carbon footprint. LEDs are also a little more efficient than Compact Florescent Lights (CFLs), but unlike CFLs, contain no mercury. However, they useВ 75 to 80 percent less energyВ than a traditional incandescentВ bulb. They may cost slightly more upfront than other light bulbs. They come in multiple shapes, color, and temperature options. They can be used indoors, outdoors, and can even be solar-powered. LEDВ ( Light-Emitting Diode) bulbs arenвЂ™t just for specialty lamps anymore.
