ive seen these fluorescent bulbs designed for people that suffer from SAD, does anyone know anything about them and if they would be any use for a planted tank, they are advertised as having a lighting spectrum very similar to the sun.

From what I remember, the lighting spectrum just mimics the sun (providing Vit D) and overall better moods.

These should be fine for a planted tank but if you go to HD or Lowes you can also get varying spectrum bulbs that would work just as well.

I take it the shops you mention are a kind of wholesale place, im in Scotland and have a business account with a place called CEF, they supply everything to do with lighting at a fraction of the cost of what a shop would charge (even for household bulbs) they have bulbs for everything, an expensive tube like the one im talking about for my 5 foot tank is about 2 pounds, one for my 2 foot tank costs about 90p. If its a bulb or anything to do with lighting they sell it.

OH!!! I didn't even look to see that you were in Scottland. Yes, sounds like you should be able to get it from your shop then.

The fixtures for sad are often PC bulbs. Other then the spectrum the only difference in the fixtures is that they tend to have very good reflectors but otherwise it is just an expensive way to get a PC fixture. I am sure there are some real crap fixtures that are sold as SAD units that do not have the brightness required or levels used in the studies confirming effectiveness for SAD.

SAD lights are sold on LUX not spectrum. It is generally reccomended that for treatment of SAD you get 15-30 minutes daily of 10,000 LUX light. So most bulbs/units are sold as 10,000LUX at X inches. (seems to me that X is useually equal to 12-21"). 10,000 LUX is suppost to be the same BRIGHTNESS as a nice clear sunny day. To me the color appears as white.

anyway, just trying to point out that LUX and Spectrum are not the same thing.
