A lot can happen in one hour. But on Twitter, that doesn’t even begin to explain it. Last week, more than 130 of you joined the Alliance, Energy Star, Cree, Inc., the American Lighting Association, and others to talk saving money with energy-efficient lighting during our second LUMEN Coalition Twitterchat. And in just one hour, together we sent out over 500 tweets and reached 210,000 people.

But in case you missed the great tips, energy-saving facts, and advice on how you can save hundreds by making the switch to energy-efficient lighting—we have you covered with the top tweets and takeaways from the chat.

So Let's Get Started

We're ready for #LUMENchat!

How long consumers can expect an LED light bulb to last?

@ToSaveEnergy, #LUMENchat The life data now being gathered suggests 10-25 years is correct. Take your LED bulbs when you move!

— Terry McGowan (@LightWiz) October 30, 2013

@ToSaveEnergy #LUMENchat @ENERGYSTAR rated LEDs range from 15K to 25K hrs - by checking for ES label you can be confident in the bulbs life.

How much can you really expect to save by making the switch?

Replace your 5 most often used lights with ENERGY STAR bulbs & save $75/yr Replace all your bulbs (about 40) & save $200/yr! #LUMENchat

If all 500 million bulbs in CA alone were replaced w/ #LED, consumers could save about $3 billion each year! #LUMENchat

Has the White House and Congress started using energy efficient bulbs?

@JazzyTJan #LUMENchat Yep. The White House is floodlighted with LEDs. Congress & Capitol us a few LEDs, but mostly FL & Inc.

What are my options for more efficient outdoor lights and recessed lighting?

@ToSaveEnergy #LUMENchat Yes. For exposed sockets look for the new weatherproof screw-in LED PAR bulbs.

— Terry McGowan (@LightWiz) October 30, 2013

Why shouldn’t you just wait a few more years for LED prices to go down?

The @CreeBulb pays for itself now and saves for years to come. Why wait for savings--the time for #LED is now! #LUMENchat

How best can I replace the 40-watt and 60-watt bulbs I’m used to?

Look at the Kelvin and Color Temp on the label. Most @ENERGYSTAR bulbs are made to match the color of incandescents at 2700-3000K #LUMENchat

What replacement should you get for dimmable switches?

@Mr__Amac @ToSaveEnergy @ENERGYSTAR #LUMENchat Great question. Look for the word "Dimmable" on the bulb, bulb carton or specs.

— Terry McGowan (@LightWiz) October 30, 2013

Some ENERGY STAR bulbs also work on 3-way switches too. Visit https://t.co/nAzN2HBoHj to find them! #LUMENchat

Is it worth it to switch my holiday lights over to LEDs?

If light strings sold this year were ENERGY STAR certified, Americans would save ~$45 mil/yr in energy costs! #LUMENchat

— ENERGY STAR (@ENERGYSTAR) October 30, 2013

Accd to @Energy, #LED holiday lights have an est lifespan of 40 seasons. But the real impact comes from the cost of energy. #LUMENchat

— AllianceToSaveEnergy (@ToSaveEnergy) October 30, 2013

It costs about 19 cents a MONTH to run 200 LED Christmas lights - 1/10 the #energy of traditional bulbs #LUMENchat

— Appliance Standards (@ASAPstandards) October 30, 2013

In addition to switching to LEDs, what else can I do to make my lighting more efficient?

@ToSaveEnergy #LUMENchat We've seen great trends in control systems including dimmers and daylighting controls - check out @LEGRANDNA

— BULBRITE (@Bulbrite) October 30, 2013

Turn off the lights when you're not in the room! #LUMENchat

— AllianceToSaveEnergy (@ToSaveEnergy) October 30, 2013

And last but not least, what’s the most important thing to remember when shopping for an energy-efficient light?

Look for ENERGY STAR! The bulbs pass 20+ tests for quality perf & have a min 2 yr warranty -2x as long as your iphone! #LUMENchat

— ENERGY STAR (@ENERGYSTAR) October 30, 2013

@LightWiz @ToSaveEnergy The cleanest, safest, most affordable energy is the energy not used. Add modern dimmers to save even more #LUMENchat
