The pulse durations are one thing, I quite agree. In which sense, 100% On would be the brightest output. Can't get current where there is none. What i'm on about though, is frequency. An LED responding differently based on the frequency at which those pulses are firing it. Admittedly, a test setup just now didn't show what I was hoping would be seen....a white LED connected across a signal generator. At 50% Duty Cycle, past 1MHz the light dimmed, which is expected really due to rapidity of the pulse train. The battery then ran out on the gen, but the idea is to vary the duration and see what happens. Ideally, a lumen tester would be part of such a test (not got one). However, it's still useful to know that it dimmed, because Slayer Exciters mostly run at around 2MHz and yet LED's will be ultra bright on A/V plugs, on a piece of wire or other means of lighting them. Not sure why, if the result tallied simply to frequency. Where I think there is room for debate or discussion, is with the frequency and the pulse duration. If we can utilise Off times then we save energy. So goes the thinking anyway  In relation to such circuits as the SJR series, that would then mean the introduction of a specific frequency and pulse cycle that matched the LEDs being used. ETA: While the thread seems to have slowed down and hopefully some may find it interesting. This relates to my last post, about the actual laser lightsaber. 'Theyve only gone and done it!' Turn this thing into stacked dots, one above the other. Shrink the whole system to be held in the hand. [youtube]GNoOiXkXmYQ[/youtube]
