Change a Lightbulb, Save Electricity and Money!




Introduction: Change a Lightbulb, Save Electricity and Money!

The hall bulbs in my apartment (which I maintain) are old incandescent, and as they die I replace them with CFL bulbs to save power - a big difference since they're on 24/7.

You'll Need:
Safety Glasses
Something sturdy to stand on
Backup light - to see what you're doing.
Replacement bulb - match the original in 'wattage' to get similar lighting results.

Turn off the power first. I can't access the switch/breaker for this bulb since it's locked in the boiler room.

I had to recalibrate my camera for the new light bulbs so they looked their natural colour - warm white - hence why the light changes colour from start to finish!

It's really that easy! (No, REALLY, it is!)

    I have just started replacing my CFLs with LEDs. They are much more expensive but use even LESS electricity: a 6-watt LED replaces a 13-watt CFL with the same light output as a 60 watt incandescent (the ideal level for a normal household lamp). Slightly less than 1/2 the power consumption, but they last about 5 times as long as a CFL and about 40 times as long as an incandescent (20,000 hours vs. 4,000 hours vs. 500 hours). They also radiate about 1/10th the heat as incandescent (heat roughly = to power consumption). Cost is about $10-12 a bulb, compared to about $.50/bulb for incandescents, so the life/cost ratio is still 2:1 in favor. GO LEDs!


    Only downside, if you live in a cold climate where you electrically heat, the lost efficiency just adds to the enthalpy of the house anyway ;)

    I loves my led bulbs.

    allso may i add that the quality control for foresents are worse then incandescent (trust me on that one i've seen quight a few) and the are dimmer then incandescent and it takes more time for them to reach the max of ther fule efishensy so if you turned off the light and left the room you would have to come back for in less then a second for it to save electricity while you were gone wial incandescent always save electricity while your gone because the have a very short amount of time to get to max efishensy

    13 watt compared to 100 watt...Even if it is dimmer (less efficient while it warms up) for the first minute, (they are getting better and better) then they instantly save 87 watts. That's hard to make up for with inefficiency for a short time. Once its warmed up, it stays that way for several minutes -- so if you turn off and back on after a few minutes the warmup period is much shorter (or none).

    Recycled properly, cfl's are way better in almost every way.

    How many people does it take to change a lightbulb? Just one.

    Well, well... It was about time someone posted an instructable about changing a lightbulb. Really. Everyone doing this could make so much difference. These things can give light for so much longer than those old ones with corporation-reduced lifetime.
    In some countries it is these times forbidden to produce any "normal" lightbulbs and recommended not to buy ones either anymore. This is progress, people.

    Without a bit of sarcasm; 4 stars.

    Thanks for the kind words - it's not earth shattering, but it makes a difference.

    Saving energy is where we should be aiming, but don't forget the mercury content in the CFL's. Saving energy versus a poison encased in incredibly sharp glass. I question the merits of the CFL being pushed in the public eye with the LED's being developed for the same purpose and lower energy consumption. Use them if you think the risk is worth it, but keep them away from kids and don't drop them!!

    Of course recycling the old ones is imperative!  Here in Canada at least they are accepted at recycling depots, as well as most hardware stores where they are sold - even wal mart has a bin for them!

    I agree 100% with the LED bulbs.  I <3 anything led.  Problem is that they havent QUITE caught up in lumens/watt and those bulbs that have (in the 90+ lm/w range) caught up are ridiculously expensive.

    I am originally from Alberta as well, so I have a lengthy history with energy production and consumption.
    Unfortunately, I do not believe the majority of people swayed into buying CFL's will treat these properly, especially now that governments are forcing them to. I am a cynic I guess.
    Get the word out about the recycling and I can commend that.

    There is some problem with this. 1 CFL cost more. 2 are almost not recyclable and light bulb are 100 % recycled 3 Watt differences between CFL and Light bulb dosnt worth it (could save more by using thermal energy to control room themp as colling unit reach easy 2000W so as the heating ones)
