LED Bulb Help needed!

[Spirytman]

I am trying to put together a small terrarium for some of my miniature orchids. I haven't purchased anything yet as i am still in "research mode". I am looking to buy some LED bulbs for the small space but I'd rather not use one with pink or blue light. I have been reading posts and looking at websites but i am more confused now then when i started! Orchids are not cheap and i don't want to kill them using the wrong bulb. So my question to you all is what bulb would you recommend for my situation? Oh the orchids i will be growing all need lower light; for example Lepanthes and Dryadella. Any recommendations?
