I need to install five lamps on dry wall ceilling, which transformer from 120 v to 12v do I need to buy for all of them?

My application was for landscape lighting, so I used a Volt Multi-Tap 0300 transformer. For an indoor ceiling application why get involved with a transformer? Why not go with 120V lamps and let them manage the voltage requirements? Depending on your purpose I would also recommend warmer lamps - look for closer to 3000 K for typical interior usage - only special applications would favor a cooler lamp. Without knowing your application a great solution for a drywall ceiling is the Glimpse 4" that mounts without the can, and taps directly into the J-box. 450 lumens, 9.5W with no height issues or transformer requirements. Barring an unusual application I wouldn't want to get involved with a transformer. My application was for landscape lighting, so I used a Volt Multi-Tap 0300 transformer.

Wire all lights in parallel. A 6amp transformer will run all 5 without any heat problems.

The voltage of these leds is 12VDC and in the wall you have 120VAC. But to connect it, you need to get a source to convert 120VAC to 12VDC.

Hello, Look for the wattage on the transformer and then add up the watts on the bulbs. So a 120 watt transformer can have 12 10 watt bulbs or 2 10 watt bulbs and 25 4 watt bulbs etc

I switched from the lamps to the LED units and used the old transformer from the initial installation. Obvious much larger than necessary since these LED's are rated at 2 watts. A smaller transformer of 40 watts will work fine with plenty of reserve to add more fixtures.

I used the same transformer that was powering my white 12V light. It works great!

No a power transformer will be needed. Search for 12V minimum of 2 AMPS to power these lights. Since most transformers come with a barrel connector and the LED lights come with a barrel receiver they plug together well. I have purchases these type of lights for 3 projects and very happy with the output.

The minimum load on the 105W transformer is 20W, hence 80W is OK. The transformer has many built-in protections, like over-current, short circuit etc, hence no voltage is output unless a working lamp (20W or more) is applied. Regards buzzing, 98% of dimmers do not, but depends on the dimmer you have.

Any transformer that will convert 120 VAC (Volt Alternating Current) into 12 VDC (Volt Direct Current), 500 ma (milli-amp) transformer, that has the proper barrel connector, will do. You most likely have one in your junk drawer.

Yes 11w are fine. Multiply wattage by number of lights to determine if transformer has enough power. In this case, the 120 watt transformer will support 10 11w bulbs (10*11=110 watts).

The input voltage is 120 volts AC. A lamp cord that plugs into any 120AC outlet will be ok. The output will be 12 volts.

Look up "low voltage transformers" on Amazon. Almost any one will work. I used the paradise gl22720 because I wanted a light sensor.

Need a transformer feeding a power cord to which the lamps attach where you want them.

Hi Gatita, The light bar is 12vdc, it can't be wired directly into existing 120v electric lines, but we will send you a transformer along with the light bar for free, the 120vac can be switched into 12vdc by the transformer, what you need to do is plug the transformer into your existing 120vac socket, and then, connect the light bar with the transformer's DC output connector .

Unfortunately, we don't carry the GU5.3 base light bulb in 120V AC. We only have this kind of light bulb in low voltage (12V).

These LED lights work on 12V DC. The Light Tech LED151 transformer takes 120V, 60Hz AC and converts it to 12V, 30KHz AC. The key is that the transformer converts AC to AC. The LED lights require DC. Look for a DC "Power Supply" that outputs 12V DC. Each strip will require about 2 amps, so if you want to run 3 strips in parallel, you'll need a power supply that can provide at least 6 amps. This supply might work for you: LE Power Adaptor, Transformers, Power Supply For 12V LED Strip Lights, 6A Max, 72W Max, US Plug

Not certain but probably. I'm guessing the transformer that it requires is 40-50wattt, I'm sure 12v/5A is plenty good.

I use a 12 v. DC power transformer. This works fine but you will need to solder the connections.
