I have 31 landscape lights in the backyard and while they are 12VDC they still consume some power. In an effort to use less power I tried 10watt bulbs, but they didn’t seem to last very long. I also tried 5 watt CFL bulbs but quality control was spotty (some bright some very dim). I tried multiple LED bulbs but they were not bright enough. I even tried high priced 5 watt LED bulb but they cast a blue color. Now after many attempts I found a 60 SMD LED bulb that cast a warm light and consumes only 4 watts rather than the 20 watt incandescent ones. Pretty geeky eh? But going from a total of 620 watts to 124 watts is pretty ding dang cool.
