What's the best light bulb for you?

when it comes to buying light bulbs what

do you base your decision on cost light

electric consumption what the

salesperson suggests all of these

questions arise from person seem alive

Bob so what do you do lie post use in a

home can greatly impact both energy

consumption and cost of electricity

overtime the three times the light bulbs

readily available in the market are

incandescent compact fluorescent which

are also known as CFLs and

light-emitting diode also known as LED

so how do you choose till you walk into

a 50 foot long aisle at Home Depot and

choose a random one do you select the

cheapest one or the one with the

prettiest packaging your best bet is to

educate yourself on which light bulb is

the best for you let's briefly learn

about each of the three kinds of light

bulbs incandescent bulbs give off a warm

yellow light and typically it lasts

about a thousand two hundred hours these

bulbs have been the center for so long

that almost all lighting fixtures are

designed to use them they are cheap the

average price is a dollar 25 per bulb

and are easily found in any store

furthermore incandescent bulbs are

fragile to handle

CFLs are available in cool white light

as well as warm yellow light but they

take time to warm up before reaching

full brightness the average price per

light bulb is three dollars and 95 cents

moreover CFLs are hazardous because they

are made using small amounts of mercury

which are toxic proper recycling is

imperative for CFLs an average LED will

last 50,000 hours and we will use about

329 kilowatt hours per year the average

price per bulb is $35 to 95 cents which

is much more expensive but favorable

because of the bolts low energy use in

summary incandescent bulbs n CFLs are

economical but to not less acts nearly

as LEDs the cause effectiveness of each

bulb choice is dependent on the usage

time now each of the light bulbs have

their own beneficial features let's say

I'm located in Phoenix Arizona what

would benefit me the most

considering that Arizona's one of the

warmest States and with incandescent

light bulbs producing 95% heat and 5%

life it is cost ineffective to use them

in comparison CFL and LED bulbs produce

around 75 percent heat although this

accounts for a small portion of the heat

collected in a home over the summer

there's a long-term cost of effects

associated with home cooling in the

summertime as presented in the graph CFL

and LEDs heat production is smaller

compared to incandescent bulbs and for

that reason it is best to eliminate

incandescent light bulbs from the bulb

recommendation now let's examine CFL and

LED bulbs LEDs have a price range from

11 to 47 dollars depending on the size

and origin of the light bulb CFL light

bulbs have a price range from 6 to 30

dollars the designing factor between

LEDs and CFLs is the both life and the

cost accumulated by replacing the whole

the following diagram is a cash-flow

four leds leds have a larger upfront

cost but the are reoccurring payments

for operation are smaller on a range of

twenty thousand hours and with a

discount rate of five percent the net

present value comes out to be for the

eight dollars and forty one cents

Halloween diagram is a cash flow for


CFLs have a reasonable initial and

operating cost on a range of twenty

thousand hours with a discount rate of

five percent the net present value comes

out to be twenty three dollars and 82

cents if the net present value for CFLs

is lower than LEDs for a range of twenty

thousand hours is there ever a benefit

of purchasing LEDs by absorbing the

following graph LEDs seems to be the

best choice because they have the

longest lifespan

however by comparing the investments

versus time of bullet holes as for

sensitive Magrath LEDs and CFLs costs

will break even after 40 years of the

light bulbs life

after 40 years both wolves have a remain

alive for 10 years with this in mind

after an additional 10 years the Bulls

will have to be replaced having to start

the lifecycle again for 80% of the 50

year lifespan the consumer will have to

spend more funding using LEDs for a

benefit of only 20% of the total life

therefore we come to the conclusion of

recommending CFL bulbs CFL bulbs best

benefit the consumer in this scenario

because they produce less heat compared

to the incandescent bulb and will be

most cost effective over the life of

poles compared to LEDs CFLs are

considered to also be the most

eco-friendly bulbs available in the

market overall I hope this benefit to

you for the next time you find yourself

in the 50 foot long aisle at a home

depot looking for a light bulb good luck
