UV LED Gel Nail Lamp,Professional 120W UV Nail Light for Gel Polish Fast Curing with 45 Lamp Beads, Lightweight LED Gel UV Nail Dryer for Salon Home

Q: how many LED lights does it have?

More than enough to get the job done.

Q: Is this uv nail lamp just as good as the one's nail techs use in their nail salon?

Hi, I would say. "It is not as high of a quality." as my personal opinion. I bought one of these and ended up having to run it twice as long as the salons do to cure my shellac polish. Perhaps spend a bit more and get one that has the appropriate wattage to do the job quickly.
