Flourish Iron is not chelated. It is complexed with gluconate in the
ferrous (+2) form. Check the archives on this... there was quite a
lively debate on this subject a few years back ;-)
Light will not affect the iron in Flourish Iron. The references I
have seen concerning light and iron in the aquarium relate to
photoreduction of iron+3 to iron+3. Since Flourish Iron's iron is
already in the +2 state it would not be affected.
