I have some lights all around my house with various indoor and outdoor transformers. Everything is working decently and all of my lights are standard low-voltage lights (Malibu, Moonrays, Intermatic, whatever). Some people have mentioned the new LED lights that supposedly have a longer life and that can get a lot of light out of a small bulb. Someone I know showed me a picture of their yard after they installed the LED lights. He was like, "That's a 3W bulb on the tree and a 5W bulb on the house a 2W bulb by the mailbox..." which seems like very small bulbs compared to my 20W, 30W, 50W, etc. and his were very bright. I have heard that the LED fixtures will connect directly to standard low-voltage wiring and transformers and that the lights come in "bright" and "warm" colors, etc. Has anyone played with these? I would consider upgrading some of my fixtures that could use a little OOMPH. Cheers.
