This 60-watt 12-Volt electronic low voltage transformer from Lightech can handle loads as low as 2.5 watts, so lower wattage bulbs can be used. Its safety features include electronic internal resettable protection, auto thermal regulation, auto thermal cut-off, and short circuit protection.
Had one lamp on a three lamp fixture over kitchen table that started acting up, going out and coming back on. Checked for loose wires etc. Then after several months the one lamp stopped working all together. I assumed there was one transformer for all three lights. Turned out each individual light had its own transformer. Replaced the transformer for that light and all was well. The best thing I can say about this transformer is that it saved me from replacing a $300 light fixture. Installed in about 5 minutes. No problems.
Is it possible to use 1 transformer to run 3 separate indoor pendant lights within 6' of wire-length of each other where each fixture contains 1 dimmable LED MR16 bulb of about 5.5W? I'd put the transformer in the 1st fixture, then use low voltage wiring from fixture 1 to fixtures 2 and 3. Each fixture currently has its own transformer, but that's because they were designed for 60W halogen bulbs.
Larry, I would suggest consulting an electrician to make sure your wiring is up to code. To answer your question, yes, it's possible to wire the pendants that way. It's similar to how puck lights are wired in under cabinet lighting applications.
Question from Paul:
Can this transformer be used to power LED outdoor hardscape lights that are specified to be dimmable and run on 8-12VAC (lights draw 2.4 watts each) (transformer would be mounted indoors)?
Paul, I would not recommend an electronic transformer for landscape/hardscape lights because generally speaking there is a great distance between the transformer and the lights. This causes an issue known as voltage drop. Instead I would use a magnetic transformer with either a boost tap or multi-tap feature to compensate for the long runs associated with outdoor lighting.
Question from Gene:
Can I use this with a 7W MR 16 LED bulb (equivalent to 35 watts)? The transformers I now have seem to have higher minimums than 7W, which I think is what causes the LED bulb to flicker.
Gene, it depends on what type of power supply your MR16 LED light bulb uses. Some are compatible with AC transformers but some require the use of a DC driver. If your light bulb is for use with AC transformers than this would be a good item since ti can handle the low wattage load.
Question from Allen:
I'm planning on picking up 2 Nora Xenon low-pro under counter lights which require a transformer. Would it be OK to use one transformer for both lights?
Allen, As long as the lights require a 12V transformer and do not exceed 60W, then yes.
Question from Richard Selman:
Can this transformer be used to replace transformers in track fixtures designed for Halogen MR16 Lamps in conversion to LED MR16 lamps? Most of the older halogen fixtures I use have so far been compatible with a range of 5.5, 7 and 10 Watt AC LED MR16 lamps but with fixtures using a different brand of 75W x 120 to 12 volt electronic transformer, I have encountered a problem with the 5.5 Watt LED lamp overheating and failing in about 15 minutes. I have concluded that this is because the 5.5 Watt LED is below the minimum requirement for this transformer though I have no literature by either by the lamp manufacturer or the transformer manufacturer to back this up. I also do not understand exactly why being below the minimum would cause the lamp to overheat and fail.
Richard, This is one of the biggest issues with LED MR16s, trying to find compatible power supplies. Unfortunately your best bet is to check with the manufacturer of the LED MR16 for the type of power supply to be used with it. It might require a constant voltage LED driver instead of a transformer. My opinion is that it's not the low load causing the LED to fail. If it's overheating then it might be that the LED MR16 lamp is not suitable for installation in a track head.
Question from Steve:
Can this transformer be used with LED light strips?
Steve, It's unlikely that this transformer will work with your LED light strips. Generally LED light strip requires a constant voltage driver NOT a transformer. I would recommend checking with the manufacturer for the exact type of power supply needed.
Question from David:
Do the hard-wired 120V connections for this transformer need to be inside a junction box like some of your other transformers, and do the 18 AWG wires get spliced with wire nuts directly to the 120V electrical line?
David, Generally a hardwire transformer needs to be installed in a junction box in order to safely store all of the wire connections. I would suggest consulting an electrician who is knowledgeable of local codes to help you determine if this is required. Yes, the wires from the input side can be wired to power using wire nuts.
