That's what I suspected. But I thought LED's should be immune to those issues.
At the time, as it typical, money only allowed so much to be purchased at a time.
When I buy the 2 sets of 8 LED cans(for a total of 16 cans), I'll definately buy them in a minimum of 1 type all at once, then the other type all at once later. Different models. 8 Opti Tri Pars and 8 RGB Zooms.
