Hi All,
It didn't work out with the last tank i tried to get but now have a 3ft tank but I'd like to pick your brains about about light fittings (and lights) for terrariums. I was thinking of getting something along the lines of this for my tank.
I see that it stands on little legs about 5cm off the top of the tank. So the approx distance from lamp to base of the tank will be ~65cm. Am i correct in thinking that this is bad as a good amount of light will bleed out? Am i better off dispensing with the legs and laying it on a perpex (or similar material) lid?

I am a little unsure of which kind of tubes to get however. My aim is to grow Cephs and Helis
4 of Tropical which has a red/blue "enchancement" (whatever that is) but from having read on here seems to be the spectrums most used by plants and checked the output chart of the bulb seems to be suitable.

Or should i include something like this in the mix which apparently is designed for photo synthesis?

Any advice appreciated!

A mixture of standard cool white and daylight should suffice and will be substantially cheaper than specialist lights. Both those you linked too has relatively little output in the main clorophyll a band at 660nm and would be more suited to a marine coral aquarium. You could put a horticultural tube into the mix, such as a Grolux, if you felt it was needed, but it probably won't be.

FIttings such as THESE are cheaper than the one you linked too and with a bit of inginuity can be suspended above the tank.
