Day-Light Classic Plus
Widely considered the gold standard by experts at the Center for Environmental Therapeutics (CET), this lamp provides a massive 12x16 inch light surface that ensures 10,000 lux at a comfortable 12-14 inch distance. Its height-adjustable stand and downward-tilting head mimic the angle of the sun, which is critical for stimulating the lower retina where circadian-sensitive cells are concentrated.
Quality & Materials
Uses high-efficiency fluorescent bulbs (UV-filtered) that provide a broad spectrum without the 'blue-light spike' common in cheap LEDs. The flicker-free ballast prevents headaches common with lower-end electronics.
Evidence & Testing
The design follows clinical protocols established in major SAD studies. It is one of the few lamps explicitly recommended by the non-profit Center for Environmental Therapeutics.
Brand Transparency
Carex provides full technical specifications including lux-at-distance measurements, which is the most important metric for light therapy.
Value Assessment
While more expensive than budget LEDs, its durability and the efficacy of the large screen provide the best therapeutic value per dollar.
Why Not Alternatives?
Unlike compact 'tablet' style lamps, the Carex provides a large enough light field that you don't have to sit perfectly still to receive the therapeutic dose. Most competitors require you to be within 6 inches to get 10,000 lux, which is impractical for daily use.
