A:Answer Thank you for your inquiry. Yes, Ottlite's LED Therapy lamp is the ONLY lamp that is producing 10,000 lux in order to elevate SAD. Even though Ottlite does not make any claim to elevate SAD with any of Ottlite's other lamps, there have been many customers over the years that swear by it. When it comes to SAD best to consult with your physician. Ottlite is recommended by the low vision doctor association across the USA.
