I suffer with SAD and a sunrise clock helps a lot getting up in the mornings and winding down at night. I have one similar to this It uses ses 14 bulbs, currently using halogen 42W but these don't last long and I managed to blow one closing a drawer! So, I'm looking for a way to use 10 to 20W leds but obviously, given its UK mains voltage that does the timed dimming, finding a suitable LED driver is difficult. There are a few out there but I've no idea which ones will work as it need it to. Also, the only commercially available dimmable led bulbs are e27 fit only, very expensive and only 12W, around 400 lumens. I need at least 600. Also the more the better. Looking to use 6400K or higher colour, as the higher temp colours are proven to be better for SAD. I can make electronic circuits and have hacked together/repaired plenty of stuff. I would rather build something than buy as I don't have £££ to spend! Does anybody have any ideas to help me get started? I'm also looking to replace my SAD bulbs, currently 85W cfls with LEDS as well.
