A while back I posted the follwing question:
------------------------------------------------------------------------------------------------------------------
Has nothing to do with HDTV but I figure there's electonics experience here.
I bought a rather inexpensive small string of colored LED light, 20 lights in
all, to use in a little village I set up for Christmas. The string takes 3 AA
batteries and has a simpl on/off switch.
It eats batteries. I was replacing them every couple of days. I have two
identical strings and they both do the same thing. I wrote to the dealer I got
them from and they said to check their ad, and it clearly states that batteries
last an average of 15 hours. I missed that, but I have a string of white LED
lights, also about 20 in the string that has been lit on the same batteries for
weeks.
My question is this. I like the lights and want to be able to use them again
next year. Can I somehow splice them into an A/C adapter and plug them in next
season? I'd have to put a switch in line, unless I wired into the little battery
box that already has the switch. Are LED's AC or DC? And do I just look for an
adapter for 4.5 volts? Thanks.
---------------------------------------------------------------------------------------------------------------------
I got many useful replies. I went ahead and found a 100-240v converter adapter
with a 4.5v output rated at 350mA. I bought it and have connected it to the
string of lights, and it works like a charm. I have a couple of other strings
that I'd like to convert from battery to the ac adapter. I just found one with
the same specs but rated at 1000mA, or 1 amp. Will this one work as well given
it's three times the output amperage wise? I don't know about these numbers
except that if I'm buying batteries, the more mA the longer the batteries last.
I'd appreciate someone clearing this up for me. Thanks again.
