Yes the light pulses during the basecoat cure.Just one query, is it right that the lamp flashes on the Top Coat setting?! I thought it was a loose wire
It also pulses for 10 seconds at the start of the 60 second Brisa cure, this will help to prevent any exothermic reaction/heat spike.
I think for this reason, and the fact the shellac colour cure is 60 seconds in this lamp that it would be a risk to think it cures Gelish or any other LED cured gel polish.
This CND lamp cures CND Brisa and Shellac.
As I also use Gelish and ACG I have ordered a Gelish 18G lamp whilst they have a great deal on this weekend.
This will bring me into the LED Age with 1 lamp for Shellac and another for Gelish and they still won't take up as much room on my desk as my 2 CND UV lamps do!
Will my Boat go faster @Lynne Baker ? NO, given my outlay this week it has probably sunk...
