I have a customer who showed me his low voltage lights in a curtain valance. The lights get progresively dimmer to the end of the run. I found that multiple runs were not run to the xfmr, and all are parrelled on one run of #12-2 romex. total is 7 at 35 watts each. The leg off the xfmr to the first light is #12 romex. I think I can fish new seperate runs in thru the holes where the fixtures are poked thru, but will have to terminate all to the one #12 switch leg coming up from the transformer located in a cabinet. My question is - will it help at all to also replace the 150 watt lv xfmr with a larger xfmr - possibly a 300 watt? Any help on this is appreciated. Thanks.
