Will this work on a 75g tank?

  • We are currently upgrading MFK. thanks! -neo
I just bought some t8 shop lights for my 75 gallon since I thought they would be more effective making it 3x48 inch tubes. I am currently using phillips 32w/ 6500k/2800 lumen/t8. Thats 8400 lumen total.

But for the 20g long, im am using a clamp light with this CFL bulb (http://www.homedepot.com/Electrical-...atalogId=10053). It is facing directly above the amazons swords to concentrate the light.
 
Yes, people have successfully lighted tanks in the hundreds of gallons using cfl spiral lights.

For a 75 i would use 4 bulbs in a row spaced out evenly over the 4ft length to spread on the light evenly.
