Do these lights help You to sleep longer?
Not on it's own. Bright light therapy, when exposed to someone at the correct time, can influence daily sleep patterns. However, bright light therapy is often only part of the regimen for better sleep. Sleep hygiene is also important and this may include going to sleep and getting up at the same time every day, weekdays and weekends, avoiding stimulants before bed (i.e. coffee, soda, energy drinks) and ensuring the sleep area is dark, etc.
Can I use this as a daily desk light? Or is it too bright or does the time need to be limited with it?
Yes! The Aura can be used as a desk lamp. The light head has the ability to be tilted down (parallel with your desktop) where it is not shining directly into your eyes and providing no therapeutic benefits. With its 4 intensity settings, you can light your workspace to your personal desire/needs.
Is this lamp full spectrum or broad-spectrum?
This is a full spectrum light therapy lamp.
Does the light feel warm?
No warmer than an led bulb.
What is the length and width of the lighted portion?
The Lamp is 11" L x 8" W x 1.5" D
