Review: Brilliant! - Great, speedy delivery. The old Christmas lights worked, but the adaptors were on their last legs. These have a higher mA than my old ones which is the correct way round (smaller mA than you need wont work!). So now the lights are back on, in safe working order - just in time to be put away for next year :). Highly recommend.

## Questions & Answers

**Q: Suitable replacement for ip20 model no. jt-240v0150 sec 24v - 150ma, 3.6va ? thanks.**
A: Hi, I brought this AC/DC Adaptor as a transformer for 150 Christmas Lights, works perfectly. It is label as: Model: BL-24v850, input 230-240V, output: 24v AC 850mA 20.4VA. It replaced one I had that had been dropped, causing a crack in it. That was label as: Model: NO:JT-240v0850 230-240V - 50Hz 24V - 850mA 20.4VA. As it looked exactly the same, with same spec, I took a chance, glad I did. Hope that helps.

**Q: Will this adaptor/transformer work for indoor Christmas lights that take JT-240V0650 pls?**
A: Have just bought the 850 adapter for Christmas flower lights because that's what they specified. Haven't tried it with other lights. Sorry

**Q: Will this be work for a 500 bulb led string fairy lights. on the plug it says transformer model yj-c32b8m-8w. mamy thanks**
A: All that I can suggest is to compare the information on the back of the plug with your original plug for your fairy lights. If it is the same it will work if not it probably will not work.

**Q: is this a suitable replacement for model no JT/360v0434a**
A: Sorry, I can't help you on this occasion.
