Finally I found the electronic pieces required for this project, and I will be getting them this Saturday. Although the project was started as an LED array lighting project, general forum decision was to go with FL light sources to achieve better diffused lighting.
Granted that none of the electronic parts are DIY, I still wanted to share my final design and thank for all the help you guys have provided.
A quick list of parts and what I ended up paying: (Probably cheaper in U.S.)
Dimmable E-ballast
EAN/ Product: 4050300870489
Product description: OSRAM QTIDALI 2X21/39/220-240 DIM VS20
Price: 2*50$*1.18 = 118.00$
High Output T5
EAN/ Product: 4050300591681
Product description: OSRAM FQ 39W/840 HO 20X1
Price: 4*5$*1.18 = 23.60$

Once I mount the fixture, I will post pictures of it and let you know if the diffused light was satisfactory.
Question:
I have 1 power line going from my light switch to the ceiling (concrete building). How do I connect two (2x39W)dimmable e-ballasts and four 39W T5 FL to 1 power line? (any sketches would be awesome)
