Cost Of Lamps??

Have to say I'm rather sceptical about the specification, even more so at that price.

My Lumie "Pharos Max" emits 10,000 lux at ~80cm, using six 36watt bulbs. It cost me ~£270 about three years ago. As far as I am aware, it is still one of the most power lightboxes on the market.

The product in your link claims 20,000 lux at 50cm, using just three 11watt bulbs. For £40, this is a "too good to be true" scenario. Personally, I'm not aware of any lightbox capable of 20,000 lux output.

The picture may not be doing the product justice, but the light intensity looks comparable to my Lumie "Brightspark", which sits on my PC desk.

I must admit it does seem a bit dodgy, the price seems very low and 20,000 lux seems very high. All the lightboxes ive seen advertise up to 10,000 lux.

I've seen some cheap LED lightboxes as well, and while they may not have all the bells and whistles, they probably still do the job. I picked up a second-hand Lite-Pad for a tenner to use while I'm quilting and it's fine.

Something I suspect may work nearly as well as a lightbox is to buy a blue LED bulb such as http://ebulbshop.com/acatalog/Blue_LED_Golfball_Bulb_BC.html and sit with it in a lamp just above your eyes. You take in the light most effectively if it's above your eyes, and blue is the wavelength that has the effect. You may need to use it for longer, but it could make a decent stopgap. I have one and tried using it for about half the day, reasoning that it would produce a similar effect at a low level to a lightbox. I turned it off at 4pm, and I had terrible trouble sleeping that night, I was absolutely wired. I've also used it occasionally as a booster when sleepy in the afternoon.
