Cattleya lights

[tyme2shine]

After a week spent informing myself about lights and changing positions of my plants I think this is the best solution of my new little greenhouse.



What you think about it? I have to make 2 addictions:

1- At Phalaenopsis’s shelf: put that green net to better exploit vertical space (so I can hang up Phal schilleriana and mariae that you can see on the ground)

2- At Cattleya’s shelf: put a decent light condition because light is the only problem I have with cattleyas.

So I’m here to ask if someone can tell me something about Cattleya lights. I grow Laelia purpurata var tipo, Laelia purpurata var carnea, C dowiana aurea, C maxima, C warneri… they all have new growths
I was thinking to put just one of those energy saving lights like this:




So what do you suggest? What voltage?

thanks to everyone
