this is cool,
i have 4X2X2 planted tank running with 7X36w FL. i can source 100x3W Cree XR-E Q5 or normal 3w LED with lens. but the most confusing part for me is the numbers of drivers to run this setup. i am not good with all current,watt,volt & AMP but i am good with soldering & DIY things.
my requirement is to have minimum numbers of driver to run this whole setup.
i feel lucky to have experts here who can answer this & help me to complete my dream project.

I would like to mention that I have used Red and Blue indian and Chinese LEDs in my canopy with a T5 Warm day light Tube. The use of T5 supresses the unwanted shades and is useful for human eye to enjoy the aquarium, whereas the Red and Blue light constitute the PAR (Photosynthetically Active Radiation) light for the plants. I am using about 30Watts on my 76.2X30.48X35 cm Planted tank successfully in place of about 60Watts (As per 2.5 Watts per Gallon). usually it is said that Red (2/3) should be more than Blue light (1/3) for the plants. Light is light whether it is from a good company bulb or from a chinese bulb the only difference is in their specifications and durability and my experience is that there are some durable Chinese bulbs also. By using Blue and Red LEDs we can cut short on Yellow and Green unwanted spectrum by the Plants and need only little of this spectrum to nicely visualise the aquarium. I will post my snaps of light arrangement if it is required.

Thank you for your interest. I am posting some snaps for your and others perusal. I have a wooden canopy in which I have fixed the holders to hold different types of light units. The blue LED lights are less in number but are brighter ones and they are kept facing horizontally for the fact that the blue light is least absorbed and can penetrate deeper in the water (even after reflection). The red LED units are more in number and of less power (I could not get them in high power as yet), they are directionally vertical facing downwards (Red spectrum is absorbed more in air and in water and converts to heat to some extent and cannot penetrate deeper ), they are about 4” apart with a spread of about 45o. There is one T5 (2’) Warm day light, Chinese tube light slightly closer to water surface. The purposes of T5 light are to reduce the undesirable colored shades in the aquarium due to Blue and Red LEDs and to provide some of least required, missing spectrum and UV to the plants. The presence of this T5 light keeps the Aquarium and the plants visually more enjoyable. My experiment is successful and my plants are growing vigorously with about half of the power consumption. You can see some snaps on the link
My plants are in the pots and I am free to keep them slightly closer to the water surface or deeper as required.

Requesting for the details such as:
How many Red LED and Blue LED, watts, cost of each led lamps. Toally how much watts you have attained and the total cost.
What are the Plants you are keeping.
I have three Cryptocorenes in different pots and one Amazon Sword in different pot which is growing vigorously.
I am also feeding the fertilisers prepared at home, and not using Co2.
And a word for Bhumin, this setup does not need any driver circuit. and it works nicely.
