I've installed 18 of these lights around my house, now that they are out of warranty I am constantly needing to work on them -- lots of intermittent issues with wires and bulbs seem to die prematurely possibly because of voltage spikes? Both Malibu's website and cust service for replacement parts are nightmares to deal with.
I have 23 of these. I replaced the bulbs with Philips LED bulbs to save energy. They work great. After 2 years the color remains, no fading, and I have not had to fix any if them. I'd like more, but they are now hard to find.
