Oxygen inhibition is even more difficult to overcome in the UV nail gel industry since the UV cure light units liberate only very low levels of UV whether it is FL or Light Emitting Diode (LED). The power output for GA-FL units is very low. The unit is pictured in Figure 3.9.

Wattage output for the GA-FL units is as low as 40W. In addition, the newer technique for UV curing of nail gels is the use of LED units that emit an even lower level of UV energy than the GA-FL UV cure units.

Power output for these UV cure LED nail gel units (Figure 3.10) is at 48W. Since now it has an even lower amount of UV energy to free-radically cure the coating, the oxygen inhibition issue becomes even more important.
