We have some low voltage Halogen spots (50W, wide angle 60\u00b0) in some portable demo kit and, aside from the Halogens being ineffecient and running very hot, they have a tendency to break if knocked. I wondered if these could be replaced with LED lights and did a quick comparison:<\/p>\n\n\n\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t

I could only find one real candidate for replacement (8W Sylvania). It’s not as bright as the original Halogen, so not a true 50W equivalent, and expensive at \u00a322.64 versus \u00a31.38 for the Halogen. However, the LED should last 6.25\u00d7 longer, and uses 16% of the power.<\/p>\n","protected":false},"excerpt":{"rendered":"
