1 lumen = 1 candela per steradian.
1 candela = 1/683 watts per steradians (assuming 540nm light wavelength).
Assuming that the light is collected from a single steradian:
1 Lumen = 1 Candela -> = 1/683 Watt -> Watt = 683 Lumens
1 Joule = 1 Watt per Second -> Watt = Joule/Second
Hence:
683 Lumen = 1 Joule/Second
Under the above assumptions1 Lumen = 1/683 Joule/Second683
1 watt/second equal to 1 Joule

1 mega-anything = 1 million of them. 1 joule = 0.000001 megajoule
If you actually mean the unit of energy, Joule, then 1 Volt = 1 Joule/1 Coulomb, or 1 Joule = 1 Volt * 1 Coulomb
Watts are units of power. Joules are units of energy. They are not the same. One watt is one joule per second.

No. 1 watt = 1 joule per second 1 watt-second = 1 joule 1 kilo-joule = 1,000 joules
There is only 1 phospholipid bilayer that separates the stroma from the thylakoid lumen.
