As we ramp up production, there is still a limited time to pre-order a SunSprite! Head to SunSprite.com.

SunSprite is the first wearable device that tracks your daily light and sun exposure. Use it on its own to measure bright light, or sync it with your smartphone to measure UV index and to deliver a personalized set of goals and tips to make sure you get the right amount of bright light to support your healthy lifestyle.

SunSprite is a leap forward in wearable technology. It's completely solar-powered. No cords or plugs. No batteries to replace. No essential cable to forget in a hotel in Des Moines.Wear SunSprite anywhere with its advanced flexible magnetic clasp. We made the magnets strong enough to go through even the thickest of winter jackets (we live in Boston, so we know about this). Just clip it in a place that gets the same amount of light your eyes do, and let SunSprite do all the work.

Getting bright light at the right time of day is clinically proven to boost your energy and help you sleep better. See Bright Light & the Human Brain below for the science behind SunSprite and bright light.

SunSprite’s dual sensors measure the brightness of both visible and UV light so you can make sure you’re getting the right amount of light — enough visible light to be healthy while avoiding too many harmful UV rays. SunSprite's LED display (as well as its smartphone app) can tell you if the light you're in is bright enough to be beneficial.

On top of this, bright light has been linked to proper eye development, reduced incidence of ADHD, lower blood pressure, reduction in body fat, and strong Vitamin D levels.

You might be asking yourself: Can’t my eyes measure brightness?

Every morning’s brightness is different. And the pupils in your eyes constantly adjust to the light levels around you – this is how you can see things in both daylight and starlight. Unfortunately, this adaptability makes your eyes a bad judge of brightness. SunSprite makes it effortless to track all your light exposure – from bright, sunny days to sunset hikes with your pup.

On top of all that, we also have a wicked cool app. It was developed by Raizlabs, the same team that crafted RunKeeper. The SunSprite app is accessible on iOS-devices (iPhone 4S or newer). And don't worry Android users, your app is coming next!  Check out a few screenshots to see how SunSprite gives you the 360 bright light experience.

Light works through our eyes. (This is different from how vitamin D is produced, which is by UV light reaching our skin.) When bright light enters the eyes, it stimulates specialized receptor cells in the retina that have connections to the suprachiasmatic nucleus in the brain – the “master pacemaker.” From there, the effects spread – more widely than doctors and scientists once thought.

Bright light sets the rhythms of our bodies, our minds, and our lives. When those internal rhythms are out of sync with our day, we feel “social jet lag.” But it’s not just a feeling. “Circadian synchronization” improves sleep, mood, alertness, cognitive performance, and well-being.

Scientific studies over the last 30 years have concluded that light therapy is just as effective as antidepressant medication not only for seasonal depression (SAD) but also for non-seasonal depression. And further research has found that bright light may also benefit a wide range of medical conditions including insomnia, ADHD, Parkinson’s disease, and dementia.

Light improves the health of the healthy, too. Those positive effects on sleep, mood, alertness, cognitive performance, and well-being apply to everyone. In addition, a recent study found that adding morning bright light to a weight control program helps reduce body fat and appetite.

(Quick clarification -- the Suprachiasmatic nucleus doesn't control all your hormones, just a lot of them.)

Light is easy to get – if it’s bright enough, you only need 30 minutes a day. And because the beneficial effects of bright light come through your eyes, you don't even need to be outside. Small lifestyle changes, like eating your breakfast while facing a sunny window, can make all the difference.

For a more in-depth look at the hard science behind bright light and its benefits, check out the White Paper written by our medical co-founders, who are Associate Clinical Professors at Harvard Medical School who recommend bright light to their patients in their private practices.

We dream of brightening the lives of as many people as possible. But to do this, we need your help.

We’ve already done a lot on our own. We’ve finished design and development of SunSprite, and we have a handful of real, working prototypes (you saw them above!). We’re ready to send our designs off to a factory in the USA to be mass-produced, but we need to cover the up-front costs of producing each SunSprite. That’s why we’re asking for your support and contributions. 

We’re also asking for your feedback. We want to know how we could make SunSprite even better. We believe we have a great product, but we know that early adopters on the cutting-edge, like you, can offer suggestions that help bring SunSprite to the next level. So send us an email, post a comment, send us a carrier pigeon, or all of the above. We promise we’re listening. 

If you share our vision of making people healthier and happier using both nature and technology, please share this page with your friends and family to help us reach – and exceed – our goal. Bright light’s health benefits can help anyone, and we can’t wait to make the world a better place.

Here is what we have left to do: 

• Finish factory tooling at our US factory (~8 weeks) 
• Factory pilot production (~2 weeks) 
• FCC Certification (several weeks)
• Volume production (2 weeks) 
• Order fulfillment & logistics (2 weeks) 
• Shipping (1 week)
• Delivery (mid-2014)

We are GoodLux Technology, a team of doctors, engineers, and designers that want to improve health on a global scale by re-imagining the intersection of technology and nature.
