Absolutely NOT. I am keeping my fingers crossed that you have discovered this answer a long time ago but for those of you who are looking for an answer to this question, the answer is definitively no. Each gel is formulated to cure at a particular wavelength. Led lamps cure at 375 nm or about and uv lamps cure at 350 nm about.
Even if the gel appears to be cured, i.e. it is hard/dry to the touch, that doesn't mean it hasn't caused a variety of issues to the nail, if you cure it with a lamp that was not designated as the lamp to cure.
Manufacturers have spent a lot of time determining the optimal curing time of each of their products based on a specific irradiance. There is no reason to believe you can circumvent all the studies, testing and regulations that went into this determination,
