Notice: Must use with the Photone or LM-3000 App available for free.

Do I need to pay for Photone? No.

But Yes.

You can download and use the app for free.

To measure your specific light accurately, you will need to unlock an additional light source which costs between $3 and $7 one-time and is valid a lifetime.

I purchased and use the Full Spec LED option.

We also offer additional Pro features (all light sources, color temperature measurements, advanced settings, additional content, premium support) as a subscription for $5 a month or $30 a year that you may cancel anytime.

You won’t be charged anything without explicit purchase.

How It Works ️ The diffuser uses a semi-transparent disc with a microscopically rough surface to scatter light evenly.

This allows your device to measure light accurately, even from different directions, thanks to the cosine corrector functionality.

Developed by Swiss experts, it ensures professional results every time. ✈️ See compatibility list with Android and Iphone Devices here: Compatibility List Weight: 0.05 lbs.
