SmartSleep Connected Sleep & Wake-Up Light
Philips is the only brand in this category with extensive peer-reviewed clinical data proving their specific light curves improve waking mood and energy. The HF3670 features high-CRI LEDs that mimic the solar spectrum without the UV hazards or flicker found in cheaper units.
Quality & Materials
Uses high-quality, flicker-free LEDs with a high Color Rendering Index (CRI) to ensure the light spectrum effectively suppresses melatonin production during the wake-up phase.
Evidence & Testing
The efficacy of Philips wake-up lights is backed by independent studies showing improved quality of waking and increased alertness. Includes AmbiTrack sensors to measure bedroom temperature, noise, and humidity.
Brand Transparency
Philips provides detailed white papers on their light therapy technology and the specific lux levels (up to 315 lux) achieved at specific distances.
Value Assessment
At the high end of the price spectrum, but the inclusion of environmental sensors and clinically validated light curves justifies the investment for chronic poor sleepers.
Why Not Alternatives?
Unlike generic competitors (like JALL or hOmeLabs), Philips uses a non-linear light intensity curve that mimics a real sunrise. Most cheap alarms jump in discrete steps that can startle the user awake, whereas this unit provides a truly fluid transition.
