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?)
