Mercury lamps in greenhouse?

I have 2 mercury lamps from when I used to keeptropical marine fish in an
aquarium.
As these lamps are supposed to replicate sunlight,I was wondering if they
could be used to germinate seeds in the greenhouse when the natural light
levels are still low?
If seeds needed light to germinate, which most don't, it would be
easier to simply sow them on the surface of the compost. Rather
than bury them one seed deep, which is the normal recommendation
for most species.
If you're going to use artificial light to bring on plants earlier,
it would probably be cheaper to do it indoors where there will
presumably already be sufficient heat.
