    Can low voltage lighting be connected in series or does it have to be connect in parallel? I'm thinking wiring in series....that the bulbs (7 watt) won't be big enough to pass enough power to work the rest of the lights correctly. Just wondering if anyone has ever tried it.(wiring in series that is)

    Yes you wire low voltage lighting in series. If you didn't you would blow all the 7 watt bulbswith the 24watt transformer not to mention all the additional wiring.:drinkup:

    Thanks for the reply splicer but don't you have that backwards? The manufacturers all show low voltage hooking up in a parallel scheme which is why I wondered about wiring them in series. (I figured it would give it a constant flow)
    I realize the examples are for speaker but it workings are the same. :)

    dude... by that comment, i see that you have no understanding of how electricity works, especially low voltagelighting

    Low voltage lighting systems are designed at 12 volts. The latest UL standard wont allow transformers that produce more that 15 volts.

    No one really has a complete understanding of "how electricity works " I think wiring methods may be an appropriate response.

    You would not want to wire these systems in series because, if one of the lamps burns out, it would kill the rest of the circuit and therefore send too much voltage to the first lamps and cause them to blow from too much voltage. Also, with low voltage you have a large amp load. The lamps could not handle that load, you would burn out a lamp pretty quickly and then kill most, if not all of the circuit.

    Wire your lights using figure # 2 in the diagram.

    If you wired the circuit in series and one lamp burned out - the circuit can not provide power to any other light - the path will be incomplete. If that happened the rest of the lamps will not light - no harm done.

    isnt that called Series parralell. Definatly dont just string them along as paul stated or you will have the christmas lights syndrom Along with many other problems as he stated.

    I really like the hub meathod of wiring. As to the guy that said you would blow a 7 watt bulb with a 24 watt trans ?????? where you getting 24 watt transformers. The bulb if its 7 watts will draw just that. Its not like a speaker with an amplifier which the amp has a variable output as volume increases or decreases. I dont like the speaker schematic. Try looking up one at Its all good just either wire it to a hub or wire it like Paul said.
