I recently purchased an Intermatic transformer (ML200RT) for a low voltage landscaping system I am planning. I am planning on using Volt and Paradise fixtures and using LED bulbs bought on ebay. However, I contacted Intermatic to make sure the transformer was magnetic and has an AC output (which it does). The rep I talked to says it does but that many manufacturers require a Class 2 type of transformer rating for LED lights and the Intermatic transformer is not. The rep said class 2 means it meet the UL, National Electrical Code & ANSI/NFPA 70 approval. I'm not sure what all this means, how important it is, and if this rules out the transformer I bought for LED lights. Thanks in advance for any help!
