Description

Measure illuminance in lux, foot-candle, or color temperature (CCT) in Kelvin — all in one, with the most accurate light meter app out there. Why waste money on a hardware meter when you’re already carrying one in your pocket? The LM-3000 offers the same quality and usability as a handheld or pocket light meter. You won't need any additional light sensor — the camera already got you covered. The LM-3000 comes with a clean and simple user interface and most importantly: No Ads! See it in action here: https://youtu.be/EJW7NfE2qCk The LM-3000 is even more accurate than almost any cheap light meter available. Besides that, its measurement algorithm delivers unrivaled sensitivity to capture the faintest lighting changes, empowering new possibilities in light pollution and health research. Developed and tested by optics scientists and engineers, calibrated using professional grade Class A equipment for all iPhones and iPads, the LM-3000 is truly a light meter you can trust! Download the app for free and use it for some time! If you like it, you may buy the unlimited battery pack to use the LM-3000 for as long as you want, even when switching to a new device. Your purchase allows us to provide an Ad-free experience and helps our small team to keep on building great apps to measure light accurately and easily. To allow the app to accurately measure light intensity (lux or foot-candle) you must use a diffuser. You can either easily build one yourself for free or get the easy-to-use Diffuser & Cosine Corrector accessory from our website (-> lightray.io/diffuser). If you encounter any problems or have feedback, don't hesitate to reach out: https://lightray.io/lightmeter#contact As a proud member of 1% for the Planet we are donating at least one percent of all our revenue to environmental nonprofit organizations. With everything that you purchase from us, YOU will be giving back!
