A Tale of Two Light Bulbs

Slide 2

Incandescent or Fluorescent?? You will be confronted with a vitality test practically regular for whatever is left of your life. This story is a case of one of the decisions you\'ll be requested that make. What sort of light would it be a good idea for me to purchase? The story behind them speaks to the situation confronted by renewable and productivity advocates in today\'s commercial center.

Slide 3

Background of Energy Use in Lighting Technologies Amount of light radiated by a light is measured in lumens. One lumen is proportional to the light radiated by one flame. A watt is the measure of power a light uses to deliver light – it is not a sign of shine. This is vital to note on the grounds that a 13-watt minimized fluorescent produces as much light (lumens) as a 60-watt glowing knob. Utilizing just a fourth of the electrical vitality.

Slide 4

On this side we have a 100-watt brilliant globule simply like we as a whole have in our homes. It\'s what we use to light our homes. This light creates 1,690 lumens of light. On this side we have a 23 watt smaller bright light bulb. It is like the tubular fluorescents in many classrooms, yet it sort of "wound" into a littler bundle and it screws into a standard attachment. This light creates 1500 lumens of light. Radiant or Fluorescent?

Slide 5

Let\'s discover! Radiant or Fluorescent? So what precisely is the contrast between these globules? How could a 100W radiant knob produce about the same measure of lumens as a 23W fluorescent?

Slide 6

slender tungsten fiber that is housed inside a glass circle. come in sizes like "60 watt," "75 watt," "100 watt" Electricity goes through the fiber, since the fiber is so thin it offers a decent piece of imperviousness to the power. This resistance then transforms electrical vitality into warmth. The warmth is sufficient to make the fiber white hot and the "white" part is light. The fiber actually incandesces in view of the warmth. Warmth is not light and the motivation behind the light will be light, 90% of the vitality is spent making heat. Radiant…

Slide 7

In bright light bulbs there are cathodes at both closures of the tube and a gas containing argon and mercury vapor inside the tube. A flood of electrons moves through the gas from one cathode to the next. These electrons catch the mercury particles and energize them. As the mercury particles move from the energized state back to the unexcited state, they radiate bright photons. These photons hit the phosphor covering within the fluorescent tube, and the phosphor makes obvious light. The phosphor fluoresces to deliver light. A bright light bulb creates significantly less warmth, so it is a great deal more productive. Bright light bulbs are 4 to 6 times more productive than glowing globules. Fluorescent…

Slide 8

Would you lift one of these up off the ground??

Slide 9

obviously you would! Changing your lights to bright light bulbs is the same idea. How? – Well we should crunch the numbers .

Slide 10

Here\'s the points of interest…

Slide 11

Environmental Concerns A solitary 20W minimal fluorescent light utilized as a part of spot of a 75W radiant globule will spare 550 kilowatt-hours over its lifetime. On the off chance that the power is created in a coal-let go power plant. The reserve funds speak to 500 pounds of coal not blazed, which implies 1,300 pounds of carbon dioxide and 20 pounds of sulfur dioxide won\'t be discharged into the air.

Slide 12

In conclusion… The investment funds are definitely justified even despite the underlying cost for purchasing a reduced fluorescent. In this way, converse with your folks about the cost funds of changing from glowing lights to smaller bright lights, it is well justified, despite all the trouble over the long haul. There is considerably less waste by utilizing conservative bright light bulbs as a part of terms of vitality waste, genuine waste and discharges into the air.
