Total lighting beginner

[Optimist]

Hi! I have decided that I would put a few of my orchids under full year lighting, especially the small brachi, and parvi Paphs, and some more smaller orchids. I bought a light(lumen/footcandle) meter, and some E27 blue/red LED grow lights.
Red wavelength: 620-625mm
Blue wavelength: 460-465mm
and I am wondering if I should also put a "white" bulb in there for any spectrum they might require not supplied by the R/B lights?

I also got a roll up "mat" type LED R/B for my small terrarium boxes.

I have been studying the light differences in the growth of various plants using different colored lights, and in some cases it isa total disaster (stalky vegetation, or "dwarved") and do not want to harm my orchids.

I can't put those little one's out again because last year they were really beaten up by the sun and heat.

So in your opinion, what is the best mix of lights?
Any other tips and hints you might give a newbie?

Thank you, Katy
