    Can I use this 12V AC adapter from the US in this country?

    Hi all, Am not completely sure on this, Recently purchased some low power consuming devices which came with USA AC adapters as in the picture. Can I use a simple pin type adapter or would I need a step down transformer? Can I use a UK adapter with 12V output? Thanks!

    12V LED Drivers

    I am gradually replacing filament & halogen bulbs with LED versions. Whilst some LED lamps work okay with standard 12V transformers, the transformers don't like low current devices, resulting in flickering. Since the idea is to save money and energy, I don't really want to outlay large sums of...

    Hi I currently have halogen lights 3 x 20w on a 12v Transformer Power 65W and I want to change them over to LED lights but I have to use the existing transformer as I'm unable to get to them to take them out and use the mains to change them over to GU10.

    Can I use a 12V DC LED bulb to replace a 12V AC filament bulb?

    Hi, I'm interested in this lamp which has a 12V AC filament bulb. It sits in a MR16 fitting, so I was thinking: If I power it with 12V DC instead of 12V AC, and replace the light bulb by a 12V DC LED bulb, it should work. Would it work? Would it be safe?

    Changing 12V Downlights to GU10 LEDs

    Does anybody here have issues with changing 12V lamps to GU10 LED lamps in the same fitting? Obviously involves taking out the transformer, changing the lamp holder and putting the fitting back. I only ask because: a) The tin cans usually have a label that says 12V b) The tin cans are not...

    Why use 12v downlights

    Do many of you choose to install 12v downlights instead of mains ones? I was thinking that doing away with the problem of the transformers failing. I still see reasonably new installations with 12v downlights.

    12v cable thickness for solar panel installation

    Hi there, I'm trying to install a 12V solar panel in my caravan. I've worked out that I'll need a 100W panel, so presuming it's working at 100% efficiency that gives me a current of 100W / 12V = 8.33A. I reality the current will be more like 6A (I think). I'll be running the cable 7-8m to the...
