No, unfortunately Shellac is only designed to cure with the CND lamp. It has a lower number of photo-initiators than many other gel polishes and the CND lamp has been specially designed (wavelength/output/bulb positioning).
Over the years there has been a fair few of threads on here of people reporting problems including service failure or breakdown and even developing allergies with the tech using the wrong lamp. Added to that it is categorically against the manufactorer's instructions so any problems will not be covered by your insurance.
Sorry, it is a difficult situation at the moment with their being no lamps available in the UK at the moment, but at least you have another product that you can continue to use on your clients for now.
The current information from S2 is that lamps are due to arrive 'in a few weeks'
