    What bulbs for 6 x 8" screen?

    Have a mature screen but thinking my 20w cfl bulbs just aint cutting it. What would you recommend for a heavy stocked/fed tank?

    Also anything I can buy on eBay that'll mount the bulbs? My screen runs horizontal in my sump and not a huge amount of space for mounting things.

    Cheers

    6 X 8 = 48 sq inches = at least 48 real CFL watts total, or 24 led watts total. More is better for dark growth.

    Check the bulbs here...

    All you need is a clip-on light, or a utility light.
