About Lumio

Created by Max Gunawan, Lumio is a one-of-a-kind light that looks like a book when closed, but opens to reveal opaque pages featuring embedded LEDs that create a modern, minimalist aesthetic. And because Lumio only weighs about a pound, it’s claimed to be a portable, rechargeable option that can be used just about anywhere.

Due to its unique book-like design, Lumio is configurable in 4 different ways and can be adapted to your lighting needs as they change throughout the day:

  • Flat on the table for ambient lighting.
  • Opened 360 degrees for a greater degree of light.
  • Open only slightly when sitting upright for directional, passive lighting useful for reading or writing.
  • Combine multiple units for custom lighting solutions.

The Story Behind Lumio

Countless products throughout history were developed during the process of inventing something else, which is exactly what happened in the case of Lumio. According to Max, the light was born while he was attempting to build a modular home that could be folded flat and placed into a compact car. However, after realizing he needed too much capital to build the whole home, Max decided to scale down the project and build a folding lamp.

Previously employed as an architect, Max focused intently on not just Lumio’s design, but on production as well. In fact, Max claims to have spent 4 months in a Chinese factory fine-tuning Lumio’s manufacturing process in order to get costs down as low as possible.

Although Lumio was originally released in July 2013 after a successful Kickstarter crowdfunding campaign—which raised more than $570K based on an original goal of just $60K—the bookish-light hit the big time after Max appeared on season 6, episode 14 of the popular Shark Tank TV program.

Although it doesn’t happen often, all 5 Sharks were blown away by Lumio’s functionality, beauty, and its ability to bring smiles to their faces. Because of this, each one made unique offers, but Max ultimately partnered with Robert Herjavec, who provided $350K for a 10% stake.

The Nitty-Gritty Details About Lumio

When closed and viewed from a few feet away, Lumio is almost indistinguishable from a book. At 8.5 inches tall, 7” wide, and 1.25” thick, Lumio’s front, back, and spine are covered with FSC certified dark walnut and blonde maple woods, each of which contain powerful neodymium magnets that allow it to be mounted to most metal surfaces.

As soon as you begin opening Lumio though, the 500-lumen, high-performing LEDs embedded in its Tyvec pages turn on, creating a warm ambient glow. According to the company, Lumio gives off about as much light as a standard 40-watt lightbulb, although this light will be diffused (versus direct) since its pages are opaque.

The company claims that Lumio’s lithium-ion battery will last approximately 8 hours (more about this in a moment) until needing to be recharged using the included MicroUSB cable, which will take 3-4 hours to complete. If you’re wondering about battery life, the manufacturer claims Lumio’s will last approximately 5 years, although it cannot be replaced once this occurs. However, Lumio is claimed to still work when plugged in even after the battery has lost its ability to hold a charge. And if you permanently mount it in place (e.g. a wall), it can even be attached to a dimmer.

Considering Lumio’s stylish design, small size, and ability to be transformed into multiple shapes, it is claimed to work in all areas of your home, whether as a table lamp, wall sconce, ceiling pendant, accent light, outdoor lighting, emergency light, or just about anything else you can imagine.

lumio usage

So, should you hand over a good chunk of change for Lumio? Could you spend this money on something that might illuminate your life better (pardon the terrible pun; we just couldn’t resist)? Consider the following:

Who Could Benefit Most from Lumio?

Although Lumio’s small size, battery-operation, and portability mean that it can be used in several different ways, each of these is fairly specific. In other words, without being attached to a constant power source, it’s probably not especially useful as a go-to lighting source in your home, so it will likely be used only on an intermittent basis.

With this in mind, we could foresee it being especially useful for reading in bed or on the couch, and for providing ambient lighting at dinner parties or other types of gatherings. During the latter, you’re looking to provide light (a fairly utilitarian purpose), while really wowing your guests with something they may not have seen before, and Lumio could fit the bill nicely.

In reality though, even as Max admitted during his Shark Tank appearance, one of the strongest benefits of Lumio is its portability, and its ability to provide warm light when outdoors, whether at the park or a camping trip. As such, if you host frequent gatherings at your home, enjoy spending quality relaxation time outdoors, or just appreciate cool lighting, Lumio might be right up your alley.

On the other had, as attractive as Lumio might be, if it’s just going to sit on your bookshelf only to emerge when the power’s out, the value might not be there quite yet.

How Functional is Lumio?

Each Lumio book light comes with a leather strap that allows it to be hung, as well as magnetic wooden pegs for mounting. And when you consider the magnets inside its covers, it seems that it really is possible to attach Lumio to just about every surface.

However, although the ability to attach Lumio to metal surfaces is pretty cool, other than your refrigerator (and perhaps your stove), how many useful metal surfaces do you really have in your home? As such, how often do you think you’ll be able to use this feature?

Also, while some might consider this a minor issue, it’s important to note that Lumio does not come with a wall charger, which means you’ll have to attach the micro USB cable to your computer (or to your smartphone’s wall adapter) to recharge.

Few Consumer Reviews for Lumio, Despite Its Popularity

Soon after its immensely successful Kickstarter campaign ended in March 2013, Lumio was featured in popular tech publications such as Gizmag, Engadget, and more. Since that time though, there has been only limited publicity for Lumio.

With that said, almost every review we read about Lumio during our research was highly favorable, with compliments for everything from its packaging and reference materials, to its clean design and beautiful glow when in use.

However, there were some relatively minor complaints. Digital Trends noted that Lumio is on the fragile side, so it might not be something you’d carry around in a bag on a full time basis. Also, the article noted that Lumio’s battery didn’t last more than 6 hours (despite the advertised 8) and that it won’t recharge while turned on.

As with Digital Trends, Cacotopos was very pleased with the product, although they noted minor distortions on the edges of some pages, in addition to its high price.

Despite having been in business for about 2 years, the company is not listed with the Better Business Bureau.

Lumio Pricing & Refund Policy

Lumio is currently priced at $190 (note: as of 1/23/15, there was an approximately 2-month delivery timeframe due to high demand).

Priced at $100, the Mini Lumio (3.75” W x 5.5” H x .875” T) not only provides light, but can also charge your portable electronic devices when on the go. You can also order an accessory bag containing a leather hanger, a micro USB cable, and 2 wooden pegs for $25.

According to the company’s website, Lumio is available at select retailers throughout North America, Europe, and Asia.

Unfortunately, there wasn’t a refund policy or phone number listed on the Lumio website, and the only contact method is either via email or an online contact form.

Does Lumio Represent a Good Value?

Based on the raving reviews, and the fact that all 5 Sharks were willing to hand over large sums of money for a stake in the company, it’s fair to say that Lumio definitely has a great deal of market appeal. However, with a price tag edging $200, how much value you’ll get out of Lumio depends where (and how often) you’ll use it.

Need light at dinner parties, outdoor at the park, or while on a camping trip? Do you love cool gadgets or lighting? Are you typically an early adopter? If so, you might find Lumio’s high price worthwhile.

Or, are you just thinking about opening Lumio’s box and promptly placing it on a bookshelf or coffee table, only to be used during emergencies? If so, you might want to think about more useful items to spend your money on.

  • Charging system broken out of the box.

    • By Thomas,

    No mater how artsy or cool it is, if the hardware is broken out of the box, this is just a paperweight. I received a brand new Lumio Mini for Christmas 2015. I plugged in my Apple USB/Lightning cable into the wall USB charger, a system that charges my iPad 2 in about three hours. Then I plugged the lighting end into the spin of the Lumio Mini and the red LED light came one. Four hours later the red LED was still on. I unplugged it and went to bed. The next day morning, I plugged it in again. By evening, the red LED light was still on. The next day, same process. Then yet the same thing another day.

    It has to have been plugged in for more than 20 hours at this point, and still no green LED illumination is seen. The unit just does not seem to recharge, or enter the mode where it knows it's fully charged. So either the charge electronics are broken/defective, or the battery inside is defective out of the box. So at this point, the charge state is unknown. Do I have hours or minutes of use? I guess I'll have to just turn it on and let it run dead.

    Better quality control should have been used in the assembly of this product. I contacted the only support venue, an email address, and it has gone unanswered after over 10 days now, even though the Lumio website promises a response within a day or so.

    Bottom Line: No, I would not recommend this to a friend

    Lumio stopped working. Light would not turn off. Contacted support and received a response 24 hours later. Response was worthless. Replied and asked for info to send unit back for repair.

    Never received another response. Great product when it worked. Now worthless.

  • Won't charge with a standard apple lightning cable.

    • By John,

    I got this as a present and it's nice.

    I couldn't and still can't get it to charge with my apple phone charger and cable.

    It only seems to charge with the supplied very short 5-inch long cable which is very flimsy, and that has to be put in the correct slot in the correct orientation otherwise, nothing will happen. The sockets the USB and lightning cable go into are hidden behind a rubberized shroud so you can't see clearly whether you have plugged the cable in or not.

    Anyway I'm not too pissed off as it was a gift but if I had paid good money for this I would have returned it and demanded they resolve these design and manufacture issues before selling at such a high price.

    Bottom Line: No, I would not recommend this to a friend

  • Malfunctions after less than one-month's use

    • By Lily ,

    I received the Lumio as a gift. Although I charged it for 24-hours before the first use as instructed, the red indicator light never turned green.

    The battery lasted only 3-4 hours with each charge. This week, after having used the lamp for less than a month, night after night the lamp shut off after less than one-hit usage despite it being charged during the day.

    Just now, the Lumio quit working altogether. I tried charging it but red indicator no longer works. Nothing's works. I haven't dropped it. I am in Southern California where there is no rain, so not humidity to on which to blame the malfunction. Will never recommend Lumio to anyone.

    Bottom Line: No, I would not recommend this to a friend

  • Don't waste your money on Lumio

    • By Sarah,

    I also received it as a gift.

    Like most of the reviewers here, my Lumio broke within a short period of time, and the customer service sucked when I tried to get the problem addressed. After using it for three months, my Lumio classic wouldn't shut off in the closed position. Customer service is practically nonexistent over there. They took over a week to respond to each of my emails. So a four email exchange took over a month. Insane.

    When someone finally did respond (after I had to chase them), they wrote back that this problem can happen if you push the USB in too hard when charging the device, then offered me a 20% discount to purchase a new Lumio. You mean you engineered a fragile product that breaks easily, and your solution is for me to buy ANOTHER one from you so it, too, can break? How stupid do you think I am?

    The thing is, I really wanted to fix the broken Lumio because I'm adamant about keeping trash out of the landfill. I offered to pay to have it fixed, and I offered to bring it personally to their studio in San Francisco and pick it up. But they responded that there's no way to fix the problem. "Unfortunately, there is no possible fix if the light is still on when the book is closed."

    So they built an expensive product that breaks easily with zero possibility of being fixed once broken which means every single one of these they sell is going to end up in a landfill? Wow. I thought LED lighting was good for the environment but turns out, Lumio is TERRIBLE for the environment.

    Please don't buy this stuff! Save the planet and keep their junk out of the landfill.

  • Designed by a goat?

    • By Michael Lebor,

    Beautiful light, but how did the USB charging hardware get past anyone but a goat, a blind goat for that matter?

    Why is the USB interface so far from the surface of the unit? Why is it covered with rubber flaps so you can't see the USB hole?

    The website says that it doesn't matter if you lose the original cable because any micro USB cable will fit. I've tried seven cables and none fit because it's too narrow.

    These guys must be laughing all the way to the bank. We have a very expensive, fake book.

    Bottom Line: No, I would not recommend this to a friend

  • Does not work and no response from Lumio

    I purchased a mini Lumio from the website, thinking it looked like a cool thing for the kids. It arrived. It does not work. No indicator light comes on when charging it. We even left it overnight charging just in case it was just the indicator light that was faulty, but nothing.

    I went to the Lumio's website. There is no telephone number to call. I should have checked that before purchasing it. Emailed a support ticket. It said I would have a response within 48 business hours. It has been 72 business hours and no response.

    Total dud and seems like a scam. Buyers should be more aware than I was.

  • Beautiful but flawed

    • By Graceann Warn,

    I bought one of the first lights and was absolutely in love with it. It is a gorgeous product and I liked supporting this company. Within 8 months, the part where the plug inserts malfunctioned and it stopped charging. I hardly ever moved the light so it was not because of rough handling. It's just a really fragile connection. I got in touch with them hoping to replace it at best or repair it at least. I was told I had extended my 6 month warranty and I could buy another for a slight discount! I was really disappointed. I had planned to make this my Christmas gift this year for a couple of friends but no way. So now I own a dead Lumio. So bummed.

  • Poor customer service. no responses. no phone numbers

    • By Julia Lichtenberger ,

    I purchased the Lumio after singing on shark Tank. It took many months to get it and was delayed a few months but their customer service was good at letting me know the delay time. After using it probably 10 times over several months, The book binding started cracking up and breaking. I can see it's very delicate. We treat it very gently and always have. I wrote them about it and asked if there was a way to get it repaired. I'm even willing to pay for that since I've had it for six or seven months! They replied stating that they could replace it for me if I gave them my information and send it back in the original packaging which we had. I gave them my information and I've heard nothing back from them. I'm now on my third or fourth email to them asking for this shipping label they said they would send me. Radio silence. I was extremely happy as I wanted to buy a few of these especially knowing that they came out with the smaller version. Any company that doesn't have a telephone number where you can call to speak to someone is ridiculous. I'm extremely unhappy.

    Bottom Line: No, I would not recommend this to a friend

  • Lumio sucks

    • By Jeff,
    • Oct 28, 2016

    I ordered this for my wife. We used it around the house for about 3 months before it broke. I think it was the charging unit as others have mentioned. We contacted them and they said they wouldn't fix it. I think they might have a 30-day warranty or something.

    It is sad that the sharks would invest so much in a company that has such terrible customer service. This product was a good idea but the company absolutely blows. $200 and they won't fix their own product? What a joke.

  • Detached and untrustworthy customer service

    • By Sarah Lynn,

    I purchased a Lumio as a birthday gift for my boyfriend on January 19th. I was told that the orders were backed up and I wouldn't receive anything until mid March. Before I knew it, mid March was here but my Lumio wasn't. Curious as to where it was, I contacted the company. They responded that same day with a very generic and basic automated response "Thank you for your purchase. We understand that you are wondering where your Lumio is. We assure you that the shipment will be arriving to us by April 6th and sent out your way shortly there after." I'm pleased that they gave me an actual date but I patiently waited until April. On April 12th with no email or Lumio, I emailed them again. They immediately sent back the IDENTICAL email that was sent to me previously. Very disappointed in their customer service. I expressed my frustration and concern for receiving the product. I was told that "we never have you an exact date". Funny enough I saved the previous email that did in fact say the date of April 6th.

    Not only is their company a joke but their product doesn't live up to the expectations they made everyone believe. I am going to make sure that Lumio knows how awful their customer service is and that they should REALLY focus on improving that if they want returning customers.

    If I could return it, I would however I haven't received it yet and they don't have a return policy. Worst customer service experience ever!

    I HIGHLY recommend not to purchase this product!

    Bottom Line: No, I would not recommend this to a friend
