[QUOTE="Evans Electric, post: 494868, member: 1408"] I heard that local councils are looking at dimming their street lighting , resulting in great savings . I am no expert in dimming LED lamps so I throw this out for discussion . If the street lights were the old style , say 200W , incandescent light bulbs and they were dimmed to 100W say, ....the 200W would be dispersed between the lamp , now 100W , and the old wire wound dimmer would swallow the other 100W . So there would be no actual saving the load remaining at 200W However LED is an animal of a different colour , is there a reduction in current when leading and lagging edges are chopped I ask?
