LED lamps use LED light (the kind of light in an office building or a school) to “cure” the gel polish to dry. UV lamps use UV light (the kind of rays in sunlight) to also “cure” the gel polish to dry. LED bulbs are thought to be safer than UV bulbs, as they transmit weaker rays. With prolonged exposure to LED light (vs. UV light), it is considered not as hazardous, as for example with excessive tanning, which can darken the skin and may lead to skin cancer with prolonged exposure to the sun’s UV rays.
All of our LMM lamp products use only LED light. Additionally, lamps with LED light use a newer technology compared to UV lamps. The LED bulb is able to cure gel polish dry in half the time needed vs. UV bulbs. Also, LED lamps don’t generate heat in the way that UV lamps do, and the LED bulb never needs to be replaced.
