Hello everybody.

I promissed to relate the experience of using full spectrum daylight lamps, so I report.

My last cycle started at october 2008 ended at june 2009, too late, the expected end was february 2009.
I installed three lamps "energy saving" each 23W real, 100W equivalent, 1170 lumens. This gives a total of 3510 lux of a full spectrum light. The idea was to make the body think winter has not even come ....

This is the first year in last ten I have not one crisis, no cycle, usually starting last october, finishing february. Nothing of all this year. Now the conditions:

- I work for at least ten hours/day in the room I installed the light.
- Last cycle retarded its end 4 months, so it's possible it's now too early to a new cycle.
- No changes at all in my life style, eating ...

I can't know if the lamps have done some work at this point, I just report, and, by the way, it's a very good light, very similar to day light, and my eyes, no doubt, have been very relaxed this test-time.

Regards. Gonzalo.

I am starting to think the same.. I went tanning.. and a week after i finished.. i went into a cycle...  unfortunately i can't install lights at my work (romantic res truant)
