I love the Shellac, but I am beginning to build a Gelish collection, too. I need to get a new lamp soon an dI don't want to have to buy two. So here's my question- has anyone tried to cure Shellac in Harmony's LED lamp? I know Gelish can be used with CND's UV. And I'm sure Shellac can be used with Harmony's UV. I'm thinking the Shellac formula is only Uv cured but just wondering if anyone has experimented with this.
