What bulbs for 6 x 8" screen?

[Foo]

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.

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

Ebay is probably best best.

[Foo]

48 total so 24 either side or is that 48w each side?

Thanks

[SantaMonica]

Yes, at least.

[Foo]

Sorry can you confirm 24 or 48w per side?

At least 24
