Hi,
Thanks for such a complete and interesting review.
3 questions :
1) With what equipment do you measure and record lumen vs time for your charts ?
2) Would it be possible to make a full chart starting at every specific mode, i.e. for the NU30 starting on boost with full battery, starting on high, starting on mid ... every time with full battery to see how the lines compare on the chart.
3) Would it be possible t make the same charts for the NU25 and HC65 ?
Best regards
Mitch
Thanks!
1. I normally have this at the end of my newer reviews. This review was one of my earlier ones and predated when I started doing it.
LuxMeter: Dr. Meter LX1330B
Integrating "sphere": Homebuilt tube-style device calibrated on otherknown lights and test results. Numbers should be considered relative to eachother and my other review figures but accuracy is in no way certified or guaranteed.
Camera:Canon SD4000IS
Multimeter:Craftsman 82170
2. It would be possible but I'm able to commit to getting it done any too quickly. In the interest of getting you an answer, I looked around for other reviews that might have tested more modes. Budda tested Turbo and High runtimes and found that High followed the Turbo curve after Turbo stepped down. (

It's not my review, his results will differ from mine, and photobucket's money grab has caused some pictures to disappear (if you're tech savy, turn on developer mode/F12, inspect element, and add "~original" to the end of the image URL and it will show up), but I trust and respect his results.
3. I do not own the HC25 or HC65, so no - not at this time. I may be getting an HC65 in for review soon, though... stay tuned. If I do get one, I will test all but perhaps the lowest mode.
