I think I'm allowed to write the name of the one I use as I certainly don't work for the company but I absolutely love my light box!
The name of the company is Nature Bright. I bought the Sun Touch Plus one and it's only $99.00..
They ship it straight to your house from their website.
It also has negative ionizer air flow...and it just sits on your table top so during the winter I just leave it on there and each morning since I always wake up at 5am all year long....I grab my cup of coffee and my phone where I read the news. It "mimicks" the blue sky.
I love it and think it really helps keep my energy levels high and keep my system in rhythm for wake/sleep cycles.
It has different timers depending on how much light you need from a 15 minute to a 60 minute cycle. I normally only use the 15 minute setting and sometimes the 30 as too much gives me a buzz and almost too much energy! LOL....I've never been diagnosed with SAD so if you have, then your Dr. may recommend the timing..
Anyway...just one particular brand/style that you may consider..the website has different choices.
