We research all models in advance to see which ones are a fit for testing. We look to ensure they have wake-up features (some SAD lamps will look similar to a sunrise alarm, for example, but if there's no gradual sunrise to wake up to they don't qualify for testing with this guide) and look to test a variety of price points and additional features to see what's really worth buying. We make an effort to select both more affordable options with less features and high-end options to compare and contrast against one another in our testing rounds.
