Full Spectrum
How long can you use a full spectrum light for?

I got as a gift a full spectrum light that is supposed to help with seasonal depression. I use it for reading and for general purpose. Someone told me that you should only use it for 30 minutes a day (they called it a "happy light." How much is too much with this light; what is the suggested usage per day?

I've never heard of an upper limit to how much time you can use it, 30 minutes is a minimum. I mean, it's good for you !!! Even so, it would still probably be a great idea to try and get 10 to 15 minutes of real sunshine any time you can, just in case, for vitamin D, and such.... Best of luck to you !!!
