A Power Company Worker Invented a Light Bulb That Stays On When the Power Goes Out — And Uses Almost $0 In Electricity
Summary: He worked for the power company for 22 years. He saw how bad it was. So he built a fix in his garage — and it screws into your normal light socket.

On February 4th, 2024, a big winter storm knocked out power to over two million homes. People sat in the dark for hours. Some for days. Kids were scared. Older folks got very cold.
Stores ran out of candles and flashlights fast. People were stuck using the same fixes their grandparents used 100 years ago.
Marcus Webb watched all of this happen from his kitchen in Columbus, Ohio. He was totally calm. Because in every room of his house, the lights were still on.
"My neighbors knocked on my door. They thought I had a big gas generator." Webb told us. "I just smiled and pointed up at the light on the ceiling."
He Worked for the Power Company for 22 Years. Then He Built a Way Out.
Webb spent over 20 years as an engineer for a big power company. His whole job was to know why the power goes out — and what happens to families when it does.
"I saw the numbers no one else gets to see," he says. "The power grid is really old. It can't handle bad weather. Every year it gets worse. And every year millions of people just sit in the dark and accept it."
But what made Webb the most angry wasn't the outages. It was the so-called fixes people had to use.
"A gas generator costs $800. You drag it out in the pouring rain and yank a cord in the dark hoping it starts. Or you light candles like it's the 1800s. None of that made any sense to me."
"The fix didn't need to be big or hard. It just needed to screw into the same socket you already have — and stay on. Without you doing a single thing."
— Marcus Webb, Power Engineer & Inventor of Eternalight
In 2022, Webb quit his job and started building. After two years of work, he had it.
He called it Eternalight — a light bulb with a built-in battery and tiny solar panels on the outside. It charges itself all day long. The second power goes out, it keeps right on shining.
No app. No setup. No work on your end. It just stays on.
It Looks Like a Normal Bulb. But It's Not.
Eternalight looks just like any bulb you've ever bought. Same size. Same bright light. Same warm glow. But inside — and outside — it's very different.
Inside every bulb is a small but powerful lithium battery — the same kind used in electric cars and medical devices. It holds a full charge for months, even when you're not using it. You never have to "prepare" it. It's always ready.
The solar cells on the outside aren't just for show. They were built using the same thin-film solar tech found in NASA satellites. They can pull energy from indoor light — not just sunlight. So even a bulb in a windowless hallway will still charge itself over time.
And the outage detection system is the real magic. It checks the power line 120 times every second. The moment it senses even a tiny drop — it switches to battery power in under a blink. No flicker. No click. The light just stays on like nothing happened.
✓Solar Charging: Tiny solar cells on the outside soak up light all day. They work from sunlight through a window, or even from other lights in the room. This keeps the battery full without using any power from the wall.
✓Instant Outage Detection: The second the power goes out, the bulb switches to battery faster than you can blink. Your light doesn't go out — not even for a second.
✓Up to 8 Hours of Battery Power: If the grid goes down and there's no sun, the battery keeps the bulb on for up to 8 full hours — or 20 hours on low power mode.
✓Fits Every Socket: Standard E26 base — same as every normal bulb. No wiring. No tools. No electrician. Just twist it in and you're done.
✓Can Cost $0 to Run: Near a sunny window, the solar cells charge faster than the bulb uses power. Your meter doesn't move. Your bill doesn't go up.
We Tested It Ourselves and Couldn't Believe How Well It Works.
When the test bulbs showed up, the first thing we did was screw one in and flip the breaker off. Every other light in the room went dark right away.
The Eternalight didn't blink. It didn't dim. It didn't go out. It just kept going — just as bright as before.
If you weren't looking for it, you'd never know the power had gone out at all.
"That moment is what I built it for," Webb said when we told him. "People see that live — and it clicks. This isn't a backup lamp. It's your real light. It just never turns off."
"I Almost Didn't Buy It…"
"Honestly I almost didn't order. I figured it was another gimmick and that the solar thing was just marketing. But my husband talked me into trying one. First week, our power went out during a thunderstorm at 10pm. Every light went off. Except one — in the kitchen where I had the Eternalight. I stood there with my jaw open. I ordered a 4-pack the next morning. That was 6 months ago and I haven't touched a flashlight since."

"11 Hours. Every Light Still On."
"I put four of these in my house in Florida before storm season. When we lost power for 11 hours, the living room, hall, kitchen, and bathroom were all still lit. My kids didn't realize the power was out until they tried to turn on the TV. No panic. No flashlights. Just a normal night. It was unreal."

"I Actually Teared Up."
"My mom is 74 and lives alone. I used to worry every time a storm rolled through. Since I installed Eternalight in her hallway and bathroom, that worry is just gone. She called me the night of the last outage to tell me the lights stayed on and she was fine. I actually teared up. Worth every penny."

Here's the Part Nobody Talks About — It Saves You Money Every Single Day. Even When the Power Stays On.
Most people buy Eternalight for the outage protection. That's what keeps them up at night. But once it's in the socket, they notice something else — something they didn't expect.
Their electric bill starts going down.
Every hour your Eternalight runs on solar, it uses zero electricity from the grid. Not a little less — zero. In a well-lit room near a window, that can mean 6, 8, even 10 hours a day where the meter doesn't move. Multiply that by every room in your house. Multiply that by 365 days a year. The savings add up fast — and they keep adding up every year after that, whether the power goes out or not.
"I bought it because of the hurricane angle," one customer told us. "But now I look at my bill every month and it's just... lower. My husband doesn't even believe me. I have to show him the statements."
"I Didn't Expect This Part…"
"I got the 8-pack after Hurricane Idalia scared the life out of us. Great for outages — but the part that shocked me was my electric bill. Our lighting bill dropped by almost $18 a month. That's $216 a year. The whole 8-pack paid for itself in under 9 months. I honestly don't know why every house in Florida doesn't have these."

Your Bill Has Gone Up Every Year for 6 Years Straight. Here's Why That Doesn't Stop.
In 2020, the average US electric bill was $115 a month. By 2024, it crossed $142. That's a 24% jump — and the US Energy Information Administration says prices will keep rising every year through at least 2030.
You can't negotiate with the power company. You can't shop around. They have a lock on your home and they know it.
Eternalight is the first product that lets everyday homeowners take some of that control back. Every hour it runs on solar is an hour the power company charges you nothing. The 8-pack covers your whole home. At current rates, that's $150–$200 in annual savings — on top of the outage protection you already paid for.
1. Families in storm states. If you live in Florida, Texas, the Gulf Coast, or anywhere that gets bad weather — power outages aren't rare. They happen every year. Light when a storm hits isn't a nice-to-have. It's safety.
2. Families with older parents. Falls in the dark are one of the top ways seniors get badly hurt. One Eternalight in a hallway or bathroom could be the most useful — and most important — thing in your home.
3. Parents with young kids. Nothing scares a child more than total darkness. And nothing helps faster than a light that just stays on — no flashlights, no fumbling, no panic at 2am.
4. People who work from home. A power outage can cost you hours of work, missed calls, and lost pay. A steady light in your home office keeps you going no matter what the grid is doing.
5. Anyone watching their bills. If your bill keeps going up no matter what you do — this gives you a real way to push back. Starting the day you screw it in.

You guys. Our power went out last night for 6 hours during the storm. Every room in my house stayed LIT. I've had Eternalight bulbs in for about 3 weeks and honestly forgot they were even special. Then the power went out and I just… kept watching TV on my laptop like nothing happened. My kids didn't even know. This is the best thing I've bought in years. Period.

Ok I have to share this. My mom is 76 and lives alone and I've been scared about her during power outages for years. I installed Eternalight bulbs in her kitchen, hallway, and bathroom when I visited last month. Last week her power went out for 4 hours. She called me totally calm and said "everything is fine, all the lights are still on." I cried. I actually cried. If you have an elderly parent living alone — please just get these. The peace of mind is worth every penny. 💛

Getting Started Takes About 30 Seconds
1
Order Eternalight through the official site while the current discount is still active. Stock has been selling out fast — especially the 4-pack and 8-pack.
2
Screw it into any standard socket — same as any light bulb you've ever replaced. No tools. No wiring. No app. It starts charging and protecting your home the moment it's in.
3
Forget it's there — until the power goes out. While every other light in the house goes dark, yours stays on. And while the grid runs normally, it's quietly lowering your electric bill every single day.
Only Available Through the Official Site — And Here's Why That's Good For You
Eternalight is not sold in stores or on Amazon. Webb made that choice on purpose — and it works in your favor.
"Retailers and Amazon take 50 cents of every dollar. If I sell through them, I have to raise the price or cut corners. I chose neither. Selling direct lets me charge you less and back it with a better guarantee than any store would allow."
That's also why the 60-day return window exists. No store gives you 60 days to test a light bulb. Webb does — because he knows it works and he wants you to find out for yourself.
The tradeoff is supply. After going viral on social media and being featured in several energy publications, Eternalight has been selling out in waves. Their warehouse has shipped over 200,000 units in six months alone — and every new shipment sells out within days.
Limited Time: 50% Off — Investigation Reader Discount
Due to the viral spread of Robert Dell's story, the manufacturer is offering a special discount for readers who found FreeView through this investigation. However, this offer is tied to the current inventory batch — once it's gone, full pricing resumes.
We lost power for two days last winter and my wife was scared the whole time. Candles everywhere, kids couldn't sleep. I got Eternalight after that and screwed them in like normal bulbs. Last month the power went out again and our house just… stayed lit. My wife cried a little. Completely worth it.

I was so on the fence. It sounds too good to be true — a light bulb that just keeps working when the power goes out? But the money-back guarantee made me feel safe trying it. Set up in 30 seconds, seriously. Now I have 6 of them. My electric bill is a little lower too because they charge from the sun through my windows. Did not expect to love this so much.

I'm an electrician so I was curious how well the solar charging actually worked. Tested mine with a meter. It really does charge from light — even from indoor light fixtures. During an outage it held steady for over 7 hours. For most storms that's all you need. Bought a 4-pack for my parents too. This is legit.

I thought about getting a generator for years. Never pulled the trigger because they're loud, expensive, and you have to run it outside. Eternalight just screws in. Stays quiet. Stays inside. Kicks on the second the grid goes down — you don't even notice the switch. I have a generator now too for other stuff, but honestly the bulbs handle 90% of what I actually needed.

I was worried it would be one of those things that needs a special base or some weird wiring. Nope. Screws right into any normal lamp or ceiling fixture. I put four in and my house is covered. The light quality is actually really nice too — not that harsh blue light. My husband didn't even notice I swapped them until the power blipped and the lights stayed on. He was shocked.

My neighbor showed me his setup after the last big storm and I ordered that same day. We live in Florida — hurricanes are just part of life here. My old backup plan was a bunch of flashlights that were never where I needed them. Now every room has real light during outages. My kids slept through a 6-hour outage last month without even knowing. That's a huge deal for us.

Single mom, two young kids, no partner to help during scary nights when the power goes out. I used to light candles and try to keep it calm but the kids were always freaked out. Since I got Eternalight the whole house just stays normal. We ordered pizza and watched a movie on my laptop during our last outage. Total non-event. I can't tell you how much that peace of mind means to me.

Three months in. Electric bill is noticeably lower — these things really do run off solar and light when you don't need backup mode. We've had two outages and both times the house stayed lit without us doing anything. They just worked. I tell everyone about these. Half my block has them now because of me.

My husband said "another gadget that won't work." That was 8 weeks ago. Last week the power went out and our living room, kitchen, and hallway all stayed bright. He came to me and said "okay, order more." He now talks about Eternalight like he picked them himself. I'll take it. 😂

Retired, fixed income, and my electric bill has been creeping up every year. I got an 8-pack of Eternalights and they've been running on solar charging most of the day. My last bill was noticeably lower. On top of that, we've had two outages this season and I haven't touched a single candle or flashlight. For someone on a fixed budget this thing is a no-brainer.

College apartment and we lose power pretty often in storms. Candles are against our lease, flashlights are annoying. My roommate found Eternalight and we split a 4-pack. Screwed them in, done. Now when the power goes out we actually don't even panic anymore. Also wild — our electric bill dropped a little too. Told everyone in my building about it.

I work in IT and I wanted to understand how the solar charging actually works before buying. The technology is straightforward — photovoltaic cells trickle-charge a lithium battery during the day. During a grid outage it draws from battery automatically. No app needed, no pairing, no setup beyond screwing in the bulb. For what this does, it's seriously impressive engineering at a reasonable price.

We had a storm knock out power for 3 days last fall. My neighbor had Eternalight. Her house was lit the whole time. I was stumbling around with a headlamp. That was the final straw for me.

Got these for my elderly parents. My dad thought I was wasting money — "it's just a light bulb, Carlos." I set them up while visiting for Christmas, took maybe 20 minutes for the whole house. Two weeks later the power went out at 9pm. Dad called me laughing. "Every light is still on. Your mother is making tea like nothing happened." He told me to order more for the neighbors. That was enough for me.

Rural Iowa. We lose power way more than city people do — bad storms, ice, downed lines. We always had candles and lanterns but it's never the same as real light. Eternalight works the same out here as anywhere else. Just screws in, charges from daylight through the windows, and stays on when the grid goes down. Country living just got a lot less stressful.

Power outages used to give me real anxiety. I live alone and the dark just feels unsafe. I tried Eternalight because the money-back guarantee meant I had nothing to lose. Screwed them in and forgot about them. A month later we had an outage and I didn't even get up from the couch — everything just stayed on. The anxiety is gone. Genuinely.

My wife and I argued for years about whether to get a generator. Too expensive, too loud, too much to store. Eternalight solved the whole argument for basically nothing. Both of us wanted normal light during outages. Done. The power went out during dinner last month and we literally kept eating. Candles stayed in the drawer. Marriage improved. I cannot believe we waited so long to do this.
