They may look crazy, but Nanoleaf makes the world’s most energy efficient light bulbs

nanoleaf lineEvery so often you come across a cool tech device that blows your mind, and makes you rethink what you thought about a gadget. In this case, it’s an everyday object that’s been re-imagined: the light bulb.

Since Edison’s day, light bulbs have been largely the same shape and structure: glass chambers with tiny wire filament inside, heated to glowing by an electrical current. While in modern days we’ve seen the introduction of compact fluorescents, and LED lights, the lowly light bulb has been largely the same, until now.

Enter Nanoleaf. The small startup, with a University of Toronto grad at its helm, began life on Kickstarter. Hoping to raise $30,000 the Nanoleaf team shot past their fundraising goal in 24 hours (2 hours, to be exact!), going on to get over $192,000 pledged to their goal of reinventing the light bulb. These can-do inventors are coming to Beakerhead, the art science and engineering festival in Calgary (September 16-20, 2015).

A whole new look: no rounded edges, no glass

So what did Nanoleaf do? For starters, they changed the shape of their light bulb from rounded, to dodecahedron — a sphere-like shape made from 12 flat plains.

“Our patented Laser-scoring process allows us to fold PCB just like a piece of origami, giving us the freedom to ‘think outside the bulb’ when designing Nanoleaf One,” explains Nanoleaf’s website.

Then they imbedded the Nanoleaf One with dozens of tiny LEDs, so much the better for being able to throw out of a ton of strong, clear and long lasting light.

“Heat robs LEDs of efficiency and longevity,” the website foes on to explain, “that’s why we use individual, tiny, pure copper heat sinks for each LED instead of the less efficient aluminum of competing bulbs. It costs more, but it’s just one of the many ways we achieve such high efficiency and long life.”

Then they decided to eschew glass altogether, and cut those flat plains from computer circuit board, aka Printed Circuit Board, or PCB. PCBs are made from something called “FR-4”. It’s a woven glass fabric with epoxy resin and other materials like plastic and copper sheets.

So why reinvent the light bulb? Nanoleaf’s Sunny Han says, “In the beginning, the three co-founders Gimmy, Christian and Tom got together to create a solar product as a solution to relieving the global energy crisis. They wanted to add an energy efficient light bulb to go with the device. However, after searching the market, they couldn’t find any LED bulbs that were as energy efficient as they had hoped for. The more they looked into it, the more they realized just how big of an impact greener lighting could have on global energy consumption, so they decided to challenge the industry and create something better.”

“The world’s most energy efficient” bulbs, and they can back that up

Nanoleaf calls its bulbs “the world’s most energy efficient” and declares their bulbs will save you about $300 over its lifetime in energy cost alone.

So how do they back that up? Nanoleaf’s Han says “Lighting Facts – a program run by the U.S. Department of Energy to regulate industry standards – has certified our light bulbs as the most energy efficient in the world. With the Bloom’s efficacy levels reaching 120 lumens per watt, our bulbs are the most energy efficient out of over 33,000 other LED lights listed in their database.”

Nanoleaf says its bulbs are 87% more energy efficient than a regular incandescent, and will last 27 years, meaning you may never need to change the bulbs in your home, for as long as you live there! At about $30 a pop, they’re right in line with the price point of other high-efficiency bulbs.

Dimmable bulbs without the dimmer switch

With the invention of the Nanoleaf Bloom, the company set another benchmark: creating a dimmable light bulb that doesn’t need a dimmer switch.  Instead by clicking the switch on whatever fixture you have it in on and off, you gain the control to dim the bulb to whatever level you choose. That’s a lot of versatility in your home.

Nanoleaf is brighter than bright: but why?

The bulbs themselves are super bright, almost too bright, but thankfully they can be easily dimmed from any switch.  They’d be great in a workplace, workshop, garage or basement, because they’ll give you what feels like twice as much light as any other bulb. Why is that? Han tells me, “the Nanoleaf Bloom is indeed a 75W equivalent. It appears to be brighter because there is no diffuser being used. Most bulbs are made with frosted white glass, which ends up causing the light to appear less bright. Since we place the LED chips right on the exterior of the bulb, the result is a very bright light. The shape of the bulb also gives it true omni-directional lighting, something that the LED industry has struggled to achieve.”

The Nanoleaf bulbs are simple to use; if you can screw in a light bulb, you can up the efficiency in your home. Getting the hang of the dimming function might take a bit; you need to start with the bulb on, then do a quick on/off cycle and wait until the bulb has lowered to the level you like, then you turn it off and on again to set that level.

Nanoleaf has big news to sharenanoleaf

The Nanoleaf folks shared with me that they have a new connected product coming out – a starter pack that will come with a smart bulb and hub, similar to bulbs you’ve read about here, like Philips Hue, LIFX, and WeMo/Osram. Want more general info on what a smart bulb can do for you? Check out my blog post.

“The smart home space is growing every day, but most of the new products out there only focus on the ability to control your lights wirelessly. Nanoleaf’s introduction into the connected space will keep in line with our focus on energy efficiency and offer convenient connectivity, but is one-of-a-kind with its unique dodecahedron design. We want to make products that will create meaningful experiences for people – something that they will remember and take with them wherever they go.”

Advice for inventors?

It’s no small feat, inventing something truly new, but plenty of people with amazing ideas never get past having a doodle and a dream.  What advice does the Nanoleaf team have for other inventors out there who may have an idea for something great?

“The best advice would be to just go out there and do it!” says Han. “The longer you wait, the more you stall and the less likely it will happen. Our CEO, Gimmy Chu, says that he’s glad he didn’t know everything he knows now. Otherwise he would’ve been more hesitant to take that initial plunge. Having a great idea is a good starting point but you need to be ready for a lot of hard work, late nights and bumps in the road.”

  3. Thanks Erin for presenting this on Kelsey’s first day back! It’s great to see that Nanoleaf has reinvented the bulb by changing the shape to enhance the product. It’s about time more businesses started to advance energy-efficient (particularly LED) lighting!

  4. I love the fact that they last so long. Also the energy saving will make it a no brainer. Kelsey is the code.

  5. Hello Erin, I just watched with interest your informative review of the smart lights (Nanoleaf). I hadn’t heard of this before and now will consider this newer technology for lighting up my house! The code word you mentioned for possible light giveaway was “Kelsey” I believe. Thanks for the insights and appreciated the update.

  6. I can see it glowing in my son’s room, great for his long reading hours. Thank you for showing us these new things. Great Canadian idea. Kelcy is the magic word.

  7. Thank you for the information on CTV Morning show. Always great to see Canadian technology. Key word Kelsey

  8. Keyword. Kelsey I would love this, I bought a new fan recently with the light bulbs in it, it’s light sitting under the night light at the dinner table. Thankyou for your time

  9. Interesting article and showcase on CTV this morning. The only thing I was left wondering was how many lumens and the colour temperature of the light, but that’s just a quick search to find. For the bloom bulb it maxes out at 1200 lumens with a temperature of 3000K or a warm light. I personally prefer daylight bulbs (5000 K), but imagine it’s just a matter of time before they are made available for this model bulb. #Kelsey

  10. Hello, the keyword is Kelsey. It was a pleasure to see and hear the demonstration and learn about long lasting lighting energy. Thank you.
