Best mics for picking ONLY voice, with no or minimum background noise?

[TrafalgarLaw]

Dude, I am telling you right now, you do NOT know enough to go picking out mics. This is why. Your original question; Your statement that all your recordings will have similar warmth voice; and your comment on the XLR connection. You need to go to a book store and sit down and read through the guidebooks; subscribe to a recording magazine and read it, and get with someone who really knows mics and let them help you.
1- Your original question. There is no such thing. A mic will always pick up other sounds. The placement and the isolation affects what it hears. You need top nitch closed headphones and do everything in isolation, one track at a time to avoid anything else being on a track. There's a lot more involved than even this.
2- Using one mic is not what makes everything have a similar warmth voice. There are different mics for a reason. But to know which one is your go-to mic for a starter, you need to know everything you can about all of them. For a good one single go-to mic I suggest a studio large diaphragm mic. (see, you're lost already).
3- The third is the connection. XLR does not do anything but make a good connection. The real issue is phantom power for condenser mics. (lost again?)
If you don't know what I'm talking about, using what I gave you will not be enough. You need to get with a professional and study those books until you know what sound waves and mics are all about. Sorry, but it's the only way.

Yes, I do prefer large diaphragm mic. But I don't know which one is suitable for my records, so that's why I'm asking for your recommendations here. My preamp supports 48v phantom power. Any furthur recommendations? Thank you

Just don't buy the cheapest, crappiest CFLs you can find, and you shouldn't have audible hum. Or buy an incandescent bulb or two.

If, by CFL, you actually mean old-style fluorescent tube bulbs, I'd recommend a high-speed electronic ballast with a frequency above 30 kHz.

If, by hum, you're getting electronic hum rather than audible hum, you need to fix your audio gear's grounding problems. For microphones, what often helps is soldering a bridge wire from the ground pin to the ground tab on all your XLR connectors.

Thank you. I'm using Phillips electronic ballast EB-C 118 TLD 220 which is 50/60Hz. That's the only model I can find in local stores. That's another reason for me to upgrade lighning to LED.

The questions are, this LED light panels use AC-DC adaptors. Most of them doesn't have ground pin. Will this be a problem? and is the adaptor itself produces hum? How about I put them in a wooden box like above reply?
