Re: Wiring LED Lights Together and Running off of 12V

Thanks everyone, for your advice. As you can see from the attached picture, I have now finished my project with just one on/off switch. I used the 3V 1A power supply. I must say that although it all seems to be working fine at present, the LEDs are much brighter than they ever were when they were po...

Re: Wiring LED Lights Together and Running off of 12V

How about this one I found on Ebay...

https://www.ebay.co.uk/itm/AC-DC-UK-3V-1A-Transformer-Power-Supply-adaptor-1-Amp-with-connector-block/223617043048?epid=1688591992&hash=item34109d4a68:g:xDIAAOSwq05dTKsE

Do you think that will do the job safely?

Many thanks,

Tony

Re: Wiring LED Lights Together and Running off of 12V

Thanks Ericmark. That does sound a bit complicated though. To find out I'd have to fit all four units with new batteries and the run them for four hours a day and wait to see how long the batteries last. Mr White said "The power rating can be bigger than you need as any device will only draw th...

Re: Wiring LED Lights Together and Running off of 12V

Much appreciated Mr White. Can I ask what you would consider not too small power-wise?

I'm just wondering what I should be looking for specifically current-wise when I'm buying my 3v transformer.

Sorry for my ignorance on this.

Many thanks,

Tony

Re: Wiring LED Lights Together and Running off of 12V

Thanks chaps. So just a 3v transformer should do the trick then.

What about current though? Is there any particular kind of transformer I should buy for this?

Thanks again,

Tony

Re: Wiring LED Lights Together and Running off of 12V

Thanks Mr White. There are actually 4 x 3v units which is why I thought a 12v transformer might be okay, providing each unit with the 3 volts they're expecting. However, having just seen ericmark's reply I'm starting to think I may have bitten off more than I can chew. Thanks to both of you anyway. ...

Wiring LED Lights Together and Running off of 12V

Hi, I've got three decorative letters and a heart which hang on the wall and are lit with LEDs. Each unit is powered by two 1.5v AAA batteries and each has its own on/off switch built into the battery compartment. However, it's a real faff having to remove each unit separately from the wall twice a ...
