I have to run 1 to 2 of these bulbs with a 110v to 12v power adapter. What is the minimum mHa rating I need for the adapter?

This LED lamp is rated at 1.44W. Your adapter, 110v to 12v would need a minimum 2W per lamp. This translates to 16.7 MA per lamp

I believe they use a 55 watt bulb, so at 12 volts, that's a bit under 5 amps.I use 2 of them on a 10amp fused circuit, hasn't blown yet.

These are 12V (probably AC only) If you will have transformer to 12V they will work technically. If you have an isntallation with multiple MR16s and you would like to change it to LED I would recommend to change the transformer to LED version. Otherwise it may not work or if it will work you will decrese the lifespan of the bulb (I work for LED manuacturing company in EU)

I only wired them up to 12 volt in my motorhome. Had four fixtures with two bulbs in each. All were wired to one circuit. Found with all eight on they were not bright enough. I tried pulling one bulb out of two different fixtures. They worked great. Have one set with two on a circuit and another with four, Those work great. I was going through 6-8 of the old flouresant bulbs a year. The oldest ones in our motorhome are two years old now. Have not had to replace any. Just be careful with too many on a circuit. Have no idea if they will work with 120 volts. Manufactures website should tell you that. I only wired them up to 12 volt in my motorhome. Had four fixtures with two bulbs in each.

I believe that the "MR16-130-50W" is a bulb rated for 130-volt power. The Torchstar LED MR-16 is a bulb designed for a 12-volt lighting system - you would have to use a transformer to provide the correct power to these bulbs if your power source is 130 volts. Also, check the photo of the Torchstar bulb, it has two prongs that project into the base - these prongs are straight pins - make sure that this shape fits properly into your fixtures. I hope that this helps.

Hello, 1， this item is without power supply, so you need to prepare a 2A 12V power supply. You can refer to Lemonbest® 24Watt 12V 2A AC Power Supply Adapter US Plug AC100-245V to DC 12V 2，this remote can only control led strips, and cannot control bulbs. Thank you!

My lamp, shipped 7-2012, uses 3.24W, 270ma @ 12VDC. You have brought up my only complaint with this item. Because these SMDs are wired as 12 sets of 3 chips in parallel, and each chip should be driven at 20ma max, optimally this board should be configured to draw 240ma, which it does at 11.75VDC. At 12VDC each chip draws 22ma, or 10% over its design specification. Since autos often supply 14V, in some applications the 'bulb' will run hot and not last as long as it should.

I have no way of knowing, the bulbs that were sent to us we for 110, they don't sell 12v. Would have been nice to know that up front,, so much for advertising the correct product. We kept the 110 v and they all started to fail after a few weeks, we ended up sending them all back and never did get a refund from these people. Amazon however took care of us just a couple weeks ago. Don't buy from this Amazon retailer.

No you will need a mogule base socket that are used with only hps/mh lighting, you can buy adapters, just remember you'll also need a ballast to light this bulb

The models I have bought are for 110VAC only you could use an adapter to reduce 230VAC to 110VAC or the company may also make them for 230VAC??If you buy this unit the bulbs do not last very long and have to be replaced . I have bought cheap replacements and they have lasted 3 years verses company replacements sometimes less than 6 months. E mail if you need anything more Charles Chalfin timfl99@hotmail.com

Here are the specs on the label of the adapter that is used to charge the light: Class 2 Power Supply, Model HT72005, Input 120 VAC 60Hz 9W, Output 12VDC 500mA. I wish I knew what all of that means, but I don't, and I hope it helps! If it were me, I'd take all of that alphabet soup down to Radio Shack and let somebody there find a replacement part. I found a few adapters online that come close, and they all cost $7 or less, but you wouldn't want "close" to risk burning out the spotlight.

have 2 - 1 for a 40w and the other for 80w bulbs. Think the spec requires 30w min load.

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).

Most likely you would be fine to use 240vac input, this bulb has a step down transformer similar to the ones in phone chargers which all work in the 120/240 range, however the input range on this product is not specified, I would feel safe trying it @ 240.. Background in electronics..

they run of of 9v I use the basic radio shack power adapter with a universal socket and bought another socket to connect to the lights and everything is running fine with it. They ran fine with 20pc as well as with 8 so I could not imagine 4 not working.

Nop..aah, this bulb requires a "MOGUL" type socket from your local hardware store, it's a streetlight mercury vapor type(bout twice as big as a household socket). The HPS bulbs will require a ballast with equal wattage. but you can opt to run it with typical household 110 current.

It depends on what bulb you use and how many lights you want to use. The current rating of the transformer should be equal to the number of lights times the current rating of the bulbs. I use LEDs in my lamps so the current requirements are low.
