Hi, Guys,
My Lambda Illuminator arrives tomorrow and I'm already thinking about the 5W LS chip in a 3D cell MAG with a Lambda-type switchmode converter.
I suspect that the overall peak light output may be more important than the rms or average light output. Therefore, a pulse-driven overdrive circuit like I assume is in the Illuminator should get the most out of the device. If you maintain the average power input to 5W, but with peaks exceeding that don't you solve the cooling problems a bit while getting more light out?
It would be great to see what could be done with this. I'd consider buying one!
If we had an average power input of 5W, we should still get 10 hours or so out of a set of 3 D cells allowing for converter losses.
Since we all know the discharge curve of alkalines, the regulator/driver circuit is important. I am pretty sure I'd prefer this approach to the direct drive approach, the Electro-Lumen's 1W overdrive AND Lambda's secret new toy are both very exciting.
Cheers,
Richard
