My apologies to all for bothering you with a stupid question. The yard
light converter converts from 120 V. AC to 12 V. AC. Not DC as I assumed.

I never would have guessed. Thanks for the help.

Check the voltage. My Malibu is 12V AC from what I remember.

I would appreciate some help with a 12 volt question.

I set up a 7 light long string of 12 volt, 40 watt bulbs on a strand
of 12 guage, outdoor lighting, copper wire. The bulbs and bases were
standard Edison screw base types. The lights were connected to a 300
watt DC converter made for outdoor yard lights. In theory, I would
like to take the same string (with lower wattage bulbs) on sailing
trips.

In 4 days, 6 of the seven lights have burned out. One light continues
to burn at normal brightness.

Any ideas or comments on these failures apprecitated.

Thanks
Tom

Thomas,
your query remains as sensible as it did before you mentioned the AC
output. The lamps would have failed from overvolts (not much is
necessary!) or vibration - whether the supply was AC or DC.

Tom,

Nothing to apologize for. I tend to think that the AC in this case
would not harm the bulbs as Rod said. Do you have a multimeter that
you can use to check the converter to see what the actual output
voltage is? Also, where did you obtain these bulbs and what were
they marketed for?

AC/DC a light bulb doesn't know the difference. Remember the High
Intensity desk lamps? Tensor was a brand? A 12v AC supply and a tail
light bulb.
