energy saving lightbulbs

[Rab]

are energy saving lightbulbs better than normal ones?

[NaiLed]

you've answered your own question

[Bioture]

I'm sorry but that was a really stupid question.

[Ignominy]

are they more expensive? how much? do they last way less long? is the environment important to you? does your power come from a non-renewable resource? do they put out the same amount/color of light?

if no, n/a, no, yes, yes, yes then definately yes, if not said answers, I don't know...

[Doc Flabby]

are they more expensive? not really
how much? liek 7 or 8 pounds
do they last way less long? last forever
is the environment important to you? not really
does your power come from a non-renewable resource? yep
do they put out the same amount/color of light? no.

if it says equivlent to 100W its more like 60"
but one equivelent to 120/125W for a decent amount of light.

First determine what goals you have in mind. That will define what "better" is.

[Noah]

Better for what? Lighting up a room? Art creation? Shooting at them?

Yes they are better because:

They use up a lot less power (which is v. important if you're moving in to a house with frieds at Uni)
They last a lot longer, so although at first they are quite a bit more expensive (doc flabby wtf? do you spend £7 or £8 on a normal lightbulb? they're like 99p for normal ones) but you'll never have to change it if you're renting the house for a year or two, they last years.


The only problem is that they take a while to light up, like when you turn them on they're not at their full brightness but it only takes a few mins for them to get up to brightness.

And like someone said, get an energy rating a little higher than what you would get for a normal bulb. Get 120W or 150W

[Fit of Rage]

Excuse me for asking what's probably pretty obvious but:

Isn't the power rating what matters in relation to energy use? 150W means that the light bulb uses 150 joules per second. How is that more energy efficient than a "normal" 60 watt (60 joule per second) bulb? Shouldn't an "energy-efficient" bulb consume less power, ie produce the same amount of light with 40W but with less heat output?

hey fu, i sent you a message, I'm still on vacation till sunday

edit: ps with love

[Jerome Scuggs]

one bulb saves $36 a year. i said fuck it and bought some normal ones

though i do have one on one of my lamps and yeah, it's pretty bright

[Subjugation]

I wasn't sure about em, but I got a good deal through a promotion the local power company was offering.

Yes, they are significantly more expensive than the regular ones, but they last much longer, so the difference in price is made up in the end.

They aren't as hot as the other ones are, so you can have a lamp next to you and not get all hot from the radiant heat.

The light emitted is brighter than the other ones once they warm up, so I like it better.


Only problem: Right when you turn them on, they need a couple seconds to warm up to their full power. So when I tried to install them on my porch light, the timer doesn't work---because the porch's light timer is not compatible with them. So I just have to use a regular bulb for the front porch, and I use the energy saving flourescent ones in all the indoor lites.

[Rab]

ok, the nature of these lightbulbs is that they take some time to light up, that is a con of having these lights, in order to choose to convert to these lights there must be a substancial financial saving.

a bulb costs about 2.50 (according to mom)
a normal bulb is 0.18 (bought them before)

a bulb is supposed to last 12 times as long as a normal bulb. 12x0.18=2.16
based on bulb costs, not worth it.

each bulb is documented to save between 5.00 and 10.00 per year on electricity bills. assuming an average of 7.50 this results in an annual benefit of 7.16 per bulb.

the apartment in question, has i think.... about 3 bulbs used often. = 21.48

question: is the reduced performance of the bulb, plus the effort of installation etc... worth that?
