I recently bought two kits for my JP and 4 red #44 bulbs were sent at 555s. The kit was wrong but according to the kit list, I was sent the right bulbs. I just stuck some green ones in there that I thought looked better but I told them to correct the list to avoid this is the future. They immediately said they would send me the correct bulbs and apologized for the mistake. I wouldn’t let them. I met several people from cointaker at the last show I went to and they were all very friendly, attentive, and helpful. I understand why the OP could be frustrated or at the very least, inconvenienced. You bought a kit and that should be the end of it. But in my limited experience, they will make it right without hesitation or, if this isn’t your first LED experience, you have a few extra laying around to get you through.
