My electrician said LED bulbs in a low voltage system will not save significant money because low voltage transformers use energy. Is this true?

It is not correct to assume that the transformer waste as much electricity when used with LEDs as it does with Halogen. Sure there is some waste but my guess is proportionately less because LEDs draw less than 1/10th of Halogen.

They are definitely cooler(less heat) so for the same light I'm sure they use less electricity

dear igor,(eu=230 V ) i always use two in series connected, use the bulb only gets a little warm. the fixture stays cool and close to room temperature. the incandescent bulbs heat the fixture enough i can keep my hand on it for long! a cool LED bulb probably means a good heat sink/transfer system and a reliable long life. at least that's how I see it.all the best from vienna walter

Yes, but they will have to be LOW-VOLTAGE (12V) MR16 LED bulbs. The fixture uses transformers in the track heads to convert line voltage to 12V--designed for 50W 12V MR16 halogen bulbs. You could use low-voltage MR16 LED bulbs, but, if you really want to use LED, you could just get a regular (line-voltage) track kit and put LED bulbs (e.g. PAR20, PAR30, etc.) in it.

The lightbulbs used are not halogen or led. The wattage for the transformer I have ranges from 7 - 11 watts using the wedge base bulb.

LED lights work very differently than the older incandescent lights, where you would simply put in a 220 volt lamp. Too high a voltage would destroy the electronics inside, probably instantly.

Low voltage bulbs like for this unit are sold at Lowes. I have not found them anywhere else.Will

A typical low voltage system is just that, low voltage. This means they usual supply 12 volts to the fixtures. The 10W LED fixture requires 120V in it's current configuration. It's possible to do some surgery on it and see if it works with lower voltage, but that requires some know-how. I agree that it would be great. Hopefully LEDwholesalers will design a fixture to work with 12 systems.

These are only one watt. So you power supply will be minimal. I would by the smallest transformer. I don't know what that would be. Perhaps a 50? With LEDs you can go small and save money! Note when you go to set your timer be advised that the red indicator is to turn on the light. A bit counter intuitive.

The bulbs that come with it are halogen. I replaced all of them with LED equivalents. I can then use a much smaller transformer and run thinner wire.

Let's see, 20x10w = 200w; the transformers are rated 150 w. If these were real transformers, there would be no issue. BUT ! These are "electronic" transformers; I am not sure how they work (or why !) but they seem to be very sensitive to being matched capacity to load. Thus, you might be better off with 2 x 100w transformers. Note too, that these are sold as "12v" transformers; the reality is they are 11 volts +/- , I think, 10%. 9.6 volts is " in spec" ! Halogen lamps are designed for 12-14 volts, 11 volts results in noticeably dim lights.

Suggest you email seller...we retro'd our fluorescent fixtures but they were all 12 VOLT. I am a big fan of LED's and for the $$$ savngs and the clean lite. I figure as more people adopt the LED their power bills will drop & the power companies will have to raise rates to make up the difference

The one 'drawback' to LED bulbs is that many do not fare very well in 'enclosed' lighting fixtures. Each little diode does not generate much heat individually, but it adds up when you group a gang of them together to produce say a 60-Watt equivalent brightness, then encase them in a plastic setting. Also, the built-in circuitry in the base of the bulb - that converts the household 115VAC to the required low-voltage DC - isn't all that efficient either, and generates its fair share of heat as well. The manufacturers of the most LED bulbs will very likely state, as a warning, that they are not to be used in an enclosed fixture. If you don't see that warning on the packaging, then maybe you found the one exception to the rule. But most likely the case will be that if you don't want melted plastic dripping off of each bulb onto that nice cut crystal lens, and the vapors setting off some loud smoke-detector noise, then you'd better stick with glass bulbs, like those stupid curly-Q fluorescent thingies.

I have an electrical engineering degree but have changed career years ago. Unfortunately, technological knowledge has slipped. However, I gave some thought concerning any potential issue if I were to use a low voltage transformer (AC of course) to power these lights. I suppose powering them with with an AC transformer may cause more degradation and shorten the life of the bulbs but other than that, I could not come up with any reason on why they won't work. So, I bought eight to put into my two lamp posts and they seem to work fine with the transformer as a power source. I'm not sure if running the lights with a DC source would produce more lumens but with my transformer, four bulbs in one lamp post still seem dark, definitely not the claimed 75W equivalent (someone already claimed that he measured the power consumed to be less than 5W instead of 9W). However, for my purpose with the lamp posts being decorative, the lumens produced seem adequate as I do have other light sources, if needed. Concerning your question of will they last, I don't expect the degradation to cut the life of the bulb by half but have no data to back up my claim.

As long as your Transformer support LED bulbs yes you can use the Bi Pin JC type LED bulbs. We do have it available with the LED bulbs for sale. LED Low Voltage Landscape Mushroom Light Rust Finish

According to one of my contractors the LED light fixtures he has encountered require a low voltage electrical. He does not believ that a LED bulb will work in this traditional fixture.

12volt led bulbs can be used inside anywhere the line voltage is 12 volts. 12 volt bulbs should never be used on household (110 volt in US) circuits.

That is the great thing about LED bulbs, they us much less electricity and do not generate any heat! The answer is yes you can.
