Can I bridge 2 low voltage transformers together?
DO NOT WIRE TWO 150W LOW VOLTAGE TRANSFORMERS IN PARALLEL! Your issue is that the 35w lamps in your fixtures do not seem bright enough to you and you want to increase them to 50w each…. 1: The fixtures are probably not rated for 50w lamps 2: I would suspect that your voltage to the existing 35w lamps is below tolerances of 10.75 volts. This could be a function of wire guage and wire run from the transformer. Try running a new 12/2 lighting wire to one or two of the fixtures and see if their brightness increases dramatically. 3: The 50W MR16 lamp uses 30% more electricity then a 35W lamp and only produces 11% more light output. Read some lamp photometric tables and you can confirm this. We rarely if ever use 50W MR16 lamps in landscape lighting applications for this reason. 4: If you really must increase the load on the lighting system, invest in a new, properly sized transformer. Nightscaping, Vista, Kichler, Hadco, Unique all make excellent LV lighting transformers that are CSA and
