The Aura Daylight is a medium-size light therapy lamp with above-average light coverage. However, it isn’t as bright as higher ranked lamps I tested. That said, it’s very adjustable, and its six timers makes it easy to set your therapy sessions.
In my light performance tests, the Aura Daylight earned a C grade overall. While it's a 10,000-lux lamp as advertised, it reached this brightness up to only 4.5 inches away. At the expert-recommended distance of 16 inches, the brightness was just 477 lux. These measurements were taken on the lamp’s brightest setting. By comparison, the Day-Light Sky and the Sunbox Sunlight Jr both reached 10,000 lux up to 12 inches away.
The Aura Daylight’s light coverage was above average but not great. Its beveled edges allow the light to cover more area, but the diffusing cover diminishes the luminous intensity. This means the light covers a good-size area but not with bright light. It's more of a glow, measuring just 477 CDs (a measurement for luminous intensity). This means the light's brightness diminishes the further you get from the center, so you don't have as much freedom to move without losing a significant amount of effective light.
The manufacturer doesn't list the lamp’s color temperature, but compared to other models I tested, it has a cooler light effect. In fact, its light is almost identical in color to the Verilux HappyLight’s, which is 6,500 Kelvin. That can be a concern, as the Center for Environmental Therapeutics (CET) recommends light therapy lamps not exceed 5,000 Kelvin – lamps with higher temperatures have a higher risk of creating aversive glare and can damage your retinas if you take photosensitizing medications.
One of the Aura Daylight’s best features is its timers. This feature alone certainly isn’t worth the lamp’s $150 price, but it's a nice touch that ensures you don't overdo it with too much light. It has six timers total, set at 15-minute intervals. In addition, the light rests in a swivel base, so you can adjust the angle of the light by as much as 45 degrees upward or downward. This makes it one of the most adjustable lights I reviewed. It also has four brightness settings. However, since the brightest setting doesn't reach the recommended range for comfort, the lower settings aren’t very effective.
The Aura Daylight has some good features – for example, six timers to help you get the right amount of light. However, its overall light performance wasn't great. Its 10,000-lux reach was just 4.5 inches, and with a low luminous intensity, you have to sit uncomfortably close to this lamp to reap the benefits of light therapy.
