Have (so far half ..) orbits so my pond. Looks great! 2 9-sets with a transformer (because cheaper). Now I still need 6-9 spots .... Can anyone tell me how many spots I to a !! Can hang transformer ?????? Keeps out the 27 spots ????????? Please "safe" to say - thank you .... I do not know much about the transformers. Great thing, I hope that the chains very !!!! long hold, otherwise the fun would be too expensive. The distance between the spots is a little too short, it is not very flexible with it.
