I have 18 x MR11 Halogen 20w 12v bulbs in a home office. Each 12v transformer supplies three bulbs on a harness. I ordered in 5w LED MR11 in 12v but 240v have arrived from eBay. I already have a new LED dimmer switch and LED drivers ready. My question is can I run the 240v MR11 without the 12v transformers? The existing load per harness is 60w at 12v. The new load would be 15w at 240v. The LED bulbs are a full glass COB type and look so much better than anything else I have found. I'm struggling to find such a good 12v equivalent.
