Luxi is a Clip-On Adapter That Transforms Your iPhone Into a Proper Light Meter


Back in March 2011, we featured an iPhone app that lets you use your iPhone as a makeshift light meter. The app apparently works pretty well, but if you’ve been looking for a fancier solution involving your iPhone, one has finally arrived.

It’s called the Luxi, and is a small clip on accessory that turns your iPhone into a proper light meter.

As with standard handheld light meters you can find on the market, the Luxi comes with a round white diffusion dome. Well, that’s pretty much all the adapter is: a clip and a dome.


The dome is designed to rest securely over your iPhone’s front-facing camera. Once it’s in place, you boot up the free app that is offered with the device (or an existing light meter app you’re already using) and you’re good to go.


Extrasensory Devices, the company behind the Luxi, claims that the diffusion dome will lead to more accurate readings than if you use the front-facing camera by itself. It also reportedly delivers “comparable results” when pitted head-to-head with professional meters:

High-end professional light meters can cost upwards of hundreds of dollars, and until recently didn’t come with a nice touchscreen-based interface. Luxi essentially puts an incident light meter in your hand for just $20.

Luxi is patent pending and will retail for $25 when it’s launched. You can support the product and pre-order a unit for yourself over on Kickstarter for a contribution of $14.
