It pairs a 40Hz flicker bulb with a compact speaker whose optical receiver detects the bulb’s pulsed light and plays a precisely synchronized 40Hz pulsed audio tone. This combined light–sound entrainment is something separate, unsynchronized light and sound devices cannot achieve. The 40Hz (25 ms) flicker timing follows the method described in MIT’s gamma research, and is intended to support focus and mental clarity.\u003c\/p\u003e\n\u003cp\u003eUse is simple: replace a bedroom or bathroom bulb with the 40Hz bulb, or screw the bulb into the included switchable lamp holder for plug-and-play or travel use. Place the speaker within about 1.5 meters of the lamp, turn the light on, and adjust the speaker’s receiver angle to set the volume.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePrecise 40Hz light and sound synchronization: the speaker’s optical receiver locks to the bulb’s 40Hz pulsed light, so audio and flicker stay in time.\u003c\/li\u003e\n\u003cli\u003eBetter than buying a light device and a sound device separately—unsynchronized sources can weaken the entrainment effect.\u003c\/li\u003e\n\u003cli\u003e9W white LED 40Hz flicker bulb with a 25 ms period and 50% duty cycle, timed by a microcontroller.\u003c\/li\u003e\n\u003cli\u003eIncludes a switchable lamp holder for out-of-the-box use and travel.\u003c\/li\u003e\n\u003cli\u003eRechargeable sync speaker: 5W max output, about 2 hours to charge and 8 hours of continuous playback, with USB power for standby use.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eKit model: 40BS (GammaTune Sync)\u003c\/li\u003e\n\u003cli\u003eFlicker frequency: 40Hz (25 ms period, 50% duty cycle)\u003c\/li\u003e\n\u003cli\u003eBulb power: 9W white LED\u003c\/li\u003e\n\u003cli\u003eColor temperature: 5700K\u003c\/li\u003e\n\u003cli\u003eBulb base: E26 (E27 compatible)\u003c\/li\u003e\n\u003cli\u003eInput: 100–240V, 50\/60Hz\u003c\/li\u003e\n\u003cli\u003eConstruction: epoxy resin full potting for heat dissipation and durability; microcontroller timing\u003c\/li\u003e\n\u003cli\u003eSpeaker max output: 5W\u003c\/li\u003e\n\u003cli\u003eSpeaker battery: about 2 hours to charge, about 8 hours of continuous playback; rechargeable via USB\u003c\/li\u003e\n\u003cli\u003eVolume: adjust by changing the speaker’s receiver angle\u003c\/li\u003e\n\u003cli\u003eRecommended placement: within 1.5 m of the lamp, with a clear line of sight to the light sensor\u003c\/li\u003e\n\u003cli\u003eWarranty: 1 year\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSize \u0026amp; Weight\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePackage \/ kit (parcel) dimensions: 12.5 x 12.4 x 7.19 cm\u003c\/li\u003e\n\u003cli\u003ePackage \/ shipping weight: 299 g\u003c\/li\u003e\n\u003cli\u003eBulb shape size: A19\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIn the box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e40Hz flicker bulb\u003c\/li\u003e\n\u003cli\u003eLight-synced 40Hz speaker\u003c\/li\u003e\n\u003cli\u003eSwitchable lamp holder\u003c\/li\u003e\n\u003cli\u003eUSB charging cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDo not block the speaker’s light sensor.\u003c\/li\u003e\n\u003cli\u003eThe speaker does not have an automatic power-off function.
