First approach the subject honestly. The question is so light and brightly worded that it resembles a corporate campaign to sell. The same words used every where to sell us things we don't want or need.
Here you go, Exchange old bulbs for new ones,
Or make them cheap and available at walmart for like 2 for 99 cents.
If the real issue is to save the world, then put your money where your mouth is. DMV's hand out free child seats, gun makers hand out free locks.
If you want to inform the public of opportunities to "purchase at cost" ways to help the world, then that's great. You could start by contacting GE, Sylvania, Phillips etc and having them STOP producing regular lightbulbs and stop the import of the regular lightbulbs.
You see, consumers aren't all looking for new ways to spend. They want new ways to save. So hand them out one to a customer free for every walmart visit, every movie rented, every tank filled. I don't mean with the prices of goods purchased raised. Work hard to make sure every house is filled with them and you will make headway. Unless its a birthday or for someone sick, how often do you buy $4 balloons? If you need one you can get a bag ful for a buck.
For years there have been light saving bulbs similar to the ones you talk about that you , to pay off. have to use many years
Investing in lightbulbs sounds dumb. No seriously. Can you see lightbulbs listed as assets in divorces, in the paper at estate sales, people fighting over them as wills are read?
If you want to make people see how necessary they are take ALL the profit, out of the picture. Otherwise its a scam.
We can do our saving as well by turning out lights we don't need, opening shades, using lower wattage bulbs. Using reading lamps if we have to.
You will have to make it a civic duty or a law otherwise.
It's interesting that you used the word "switch" in your question.
You probably meant "BUY" which is a dirty word in add campaign jargon. Avoiding it, puts the question in the category of suspicious questions and invites the stigma that goes with it.
Nothing personal. But if someone came to my door, used the word, was declined, then offered a free gift, I'd refuse on principal.
The public, is deluged with false advertising, Get a FREE phone, but not unless you pay for a service contract. Satelite dish companies are the most brazon.
My advice is to be honest, not annoying.
Let Ellen and Oprah give them away. One thousand per patron and a personal verification that every one was screwed in a socket in a home somewhere and when its done they get new cars or something. Or adopt 1 community in each state and replace ALL the lightbulbs as a free public service, collect all the old bulbs, destroy them , make the old ones illegal to sell or posess within the city. Track savings, Have film Icons carry them, use them for grooming, as murder weapons, have truck loads stolen, have Bond go on a mission to stop Spectre from destroying the worlds supply of them. Lets see speakers carry and display them on films and at the oscars....lol
Start a fad for Rap artists to carry them taped to their bling and hats etc.
Tape one to Hillary Clintons head. Maybe two lol These aren't bad ideas. Really. Many citizens will actually see this as cool and fall for it bringing it into more homes.
Magic shows with dissapearing lightbulbs.
If Hillary is FOR the use of them maybe she will play along. It is sure to get her on every channel and on every newspaper, as well as mentined and her image seen on every talk show for months, if not years. Say, "C'mon Hillary, do it for the planet" and she has just got to say yes. Just think of the exposure, not to mention hat and t-shirt sales. lol
Have the cast of "Extra" carry them and not mention exactly why for a week and cause a national buzz. Let the cast of Lost discover a burried cache of them on the island. Let 'House" discover a rare disease miraculously cured by the bulb continous use over a patient who has too much vitamin D.....since the wavelength of light produced by the little florescent doesn't help the body produce it.....
Boy this is fun.
Have America's funniest videos have a special on Bulb vids.
Put them on UTUBE. Have kids sell replacements door to door instead of expensive wrap, stale popcorn and subscription we don't want or need.
At the drive up window they ask, "do you want to "TRY a Whopper special today"
I think, SURE lady, as long as you are just handing them out. But its a sales pitch. Its a half truth, its a turn off.
By the way, this is free advice. A small sacrifice to save the planet. Lets see the world of business do the same.
