Sadly, there is not a single lamp out there that will work with a large variety of gels. That is because every light emits differing levels of UV light (UV emissions are different than Wattage as some 4w bulbs emit more UV light than some 9w bulbs) and every gel requires differing levels of UV light to cure.
Sure, any UV light will cure any gel... but one of the most important aspects of gels is to
fully cure them. Some gels suffer dramatically through overcuring, all gels suffer dramatically through undercuring. The vast majority usually undercure gel and that can lead to virtually every type of service breakdown possible. Even though the gel looks and acts cured, you really have no idea if it is if you are not using the manufacturers lamp/gel/instruction combo.
Hope I havent confused the issue at all... there is so much I could write on this topic and much has already been written, try a search for lamp in the Main forum and see if you find any more info to help.
Hope this helps
