Well I am taking the leap, marking the end of summer by purchasing this light box:

It's not the least expensive option, but it's portable (about the size of a laptop), has three different brightness settings and the brightest is 10,000 lux at 30", while most have to be 12-15" away for that level of brightness. It uses LED lights, which I think is one reason for the higher price. Over the years I've had migraine-related problems with glare from overhead fluorescent lights; as I've gotten older and the migraines have subsided this has been less of a problem, but still I think LED lights will be less likely to annoy me. I have two LED lights at home that are not a problem.

Due to the migraine photophobia I have long been in the habit of not using bright lights indoors and wearing dark sunglasses all the time, even sometimes in the rain. So there is a chance that I won't be able to use any light box, but I am hoping I can make this work. If not, there is a 60-day guarantee.

I'm planning to start using the light box on the least-bright setting next month and gradually increase the brightness and duration as winter settles in. I am also going to take other measures to get more natural light, like spending more time near windows during the day and either not wearing sunglasses or switching my very dark Oakley lenses to something lighter.

If anyone is interested, here are other TE threads on the topic and some other information I found on the internet that seemed legit and was helpful.
