Although every product line requests that you use their branded products throughout any service, they still basically cure the same under the required time (LED/UV different timed seconds per coat) under any lamp. Many may disagree but I use different lines with different lamps and have yet to run into issues. We guarantee our gel work up to 10 days and rarely have issues (sometimes a chip or lift). Nail prep work is the most important for adhesion, so as long as the nail plate is prepped properly, I don't see why you'd run into any issues. I'd suggest doing some trial and error for yourself to see if you feel comfortable straying lines from lamp to lamp. Personally I use Gelish II lamps for most of my products but also have cured other brands under a CND lamp. I hope this helps a little and good luck!
