12V / AC, 0 - 70W, Transformer, LED driver with No minimum load, No LED flickering and No transformer noise, Dimmable Power Supply

Amazing but... pay attention to the details!First of all - delivery with Amazon - fast as usual. The transformer killed instantly the LED flickering in my house, although there were 2 LEDs which still flickered, but in the end I found out (by swapping with working LED bulbs) the LEDs were defective. I replaced them and everything is working fine now. Attention should be paid to the 20% power reserve. Like with every other transformer the max. watts are just for short peak moments. I planned with max. 56VA per transformer. In my case 10 LED bulbs with each 5.5 watts. If you use a dimmer you have to count in that the dimmer uses power as well or at least increases the VA. I have 3 rooms with more than 60 watts light power in each one and quite long distances between the bulbs + small old cable cross-section. I decided to use the 105W version of this transformer, as it was cheaper than getting two with 70 watts. Works great as well and no LED flickering.Someone asked here how to open the power supply terminal and I found the Youtube video quite helpful. I bought 17 transformers and 1 didn't work from the beginning. They have a really helpful customer service and I got a new one within 24 hours.I'm very pleased with the products and customer service. Highly recommend it.

All my halogen bulbs were replaced by my energy supplier with LED low energy bulbs. Five were 12v transformer fed (four in the bathroom,one in hallway). While all GU5.3 6.3 12v Philips bulbs worked the four in the bathroom gave starting problems. I bought this transformer and they are stable, bright and excellent. The single was being fed from a very old wire wound transformer that was very unstable. As this was no longer listed on Amazon I bought a 20W (Red) ISOLED one but that did not work with the same bulbs. It would appear that GU5.3 12v bulbs can be AC or DC, I presumed that all 12v GU 5.3 bulbs would be the same.I also had all my 230v mains fed bulbs changed and these cause bad wi-fi and radio interference. This transformer does what it says no interference at all.

Worked well for a little over a year then failed after letting out the magic smoke. Not under heavy load , so would have expected it to work for longer.

Bought this to rejuvenate my bathroom mirror unit which was use the old fashion transformer to power G4 25w bulbs. I simply replaced the transformer and the bulbs to LED G4 PIN 10. Solved my flickering issue as well.Giving 4 stars as this came with no instructions on wiring, simply bubble wrapped in an envelope.There's a youtube video on how to open the ends to access where wires need to be screwed down, see the product description.

This initially worked perfectly with a halogen 12v / 50w spotlight, and was bought because it should also work with LEDs which I intend to use eventually to replace the halogen lamps. Unfortunately it stopped working after about 3 months, which is beyond the date at which I can return the item.

I have spots in my loft conversion and one driver seemed to be constantly blowing bulbs. I have been going through a process of changing to spots when they blew, but then a driver packed in. After lots of reading I understand that the normal Halogen drivers need a minimal load to operate and can blow if you don't get it (I think). Anyway, I thought I'd try out an LED specific one.First things first, make sure your lighting circuit is off, and check it is off before starting work. AND make sure no clever person is going to fix the problem by turning it back on at the RCD box.From here fitting was pretty straight forward. The box un-clips and wiring was nice and easy. Put it all back together and slot it in the hole and it was working perfectly with and LED spot.

Installed with 2xPhilips Dimtone MR16 6.5w LED bulbs for a load of 13w. I purchased one unit as a test. My initial impression: Extremely smooth dimming performance with a large dimming range. Excellent compared to earlier LED products I have had. Instant startup. The unit appeared well built with high quality terminal blocks - very large for mains connection side which is good for loop lighting side of 220v AC side. the secondary side terminals were appropriately sized for a max 70w load at 12v.After 1day I can't remark on reliability, but I was able to find data on this unit elsewhere online - it seems a legitimate brand - and will now purchase an additional 15 units this evening. Happy customer!

This transformer does NOT dim to zero. Fitted to run x6 Osram dimmable LED MR11. I would say it dims from 100 to 40 max. Disappointed.
