I'm trying to run two 12V 12W auto lamps off a Tripp-Lite 12V 3A linear regulated power supply. One lamp will work, but two of them shut down the power supply, presumably because the inrush current is too high. Inrush current for an incandescent lamp is about 10x the current after warmup.
Is this likely to be better or worse with low-end switching power supplies, of the type usually used to power laptops and such? (Assuming I get power supplies with CSA, UL, or GS safety certification?)
