I've a 10 gallon heavily-planted aqua-terrarium with 2 9-watt screw-in
C.F. 6500K bulbs and a heavily-planted 15 gal. cube tank with one
9-watt 6500K and one 20-watt 6500K of like kind and they've both been
running with these for well over half a year and they're doing
wonderfully... never had such dense plant growth. I'd recommend them
personally. Sorry you had such bad luck with them.

Well, I used warm whites. Useless. No doubt proper 6500K ones work better,
plus you're at about 2 watts/gallon. I was unable to get as good growth
with 1.3 W/gal; as I did from .80 W/gal using a T12 bulb.

They're justnot big enough for larger tanks and if you use enough of them
to price even lighting you just spent way more than if you'd gone T12/T8.

They're small bulbs. They're probbaly ok for small tanks if you shell out
for decent ones with a decent color spectrum I guess, but my thinking
these days is LED's are a better choice than screwins for that sort of
tank.
