Candles in it?
Are you talking about this cage? -there are candles standing in front of it 
For this one I use one 70 W HQI D Metal halide, one 150 W Metal halide of the same type plus 4 x 23 W incandescent fluorescent bulbs for lighting.
The pic is old, today the plants in the cage are much more dense and grow a lot.
So I have to remove part of the vines, the fucus and the Dracaena on a regular basis.
Vines are fixed to sticks crosoing the top screened top of the enclosure.
The tank has a backwall built as fake rocks from styrofoam, PU Foam and concret.
Several flower pots are integrated into this wall and diverse plants vine out from this region covering the backwall and part of the side walls.
These days this cage harbours plants of the following geni: Dieffenbachia ; Dracaena (2 species), Ficus (pumila, benjamini, elastica); Neoregelia (2 species), Guzmania, Aechmea, Hoya, Passiflora, Philodendron (just scandens) and Epipremnium. In the water bassin Riccia, Ceratopteris and Shinnersia are growing.
Hope that helps
Ingo
