I've posted this on Dark Places after a request for detailed output levels so though I'd post it here as well...
Latest StenLight output levels in lumens:
These are LOW / MEDIUM / HIGH / TURBO without thermal limiting
R70: 4 / 25 / 80 230
R100: 5 / 38 / 130 / 360
(For comparison, equivalent figures for the Luxeon III would be 3 / 12 / 45 / 140)
These are average readings of production lamps, i.e. they factor in light loss due to optics. These figures are deliberately conservative. Peak on the R100 was in the region of 380 and on the R70 was 260.
In practice the flood is brigher and more intense and the beam will penetrate a lot further.
Battery life span is largely unaffected, both the R70 and R100 are more efficient than the old Luxeon III, and the R100 more so again than the R70. Feedback we've had from customers suggests that in practical use High on the R100 is a wee bit brighter than turbo was on the Luxeon III, consequently people are saying they use Turbo less.

my orders are to sit here and watch the world go by
