This driver is single mode only and is fortunately not inflicted with the dreaded next mode memory. The driver does indeed operate over the advertised voltage range. Tested output on 3.5 to 4 volts was surprisingly good with led current draw off .91 to 1.45 amps. I’m not sure on the efficiency off the driver. l’ll leave that for the experts. The disappointment was the output on a single AA NiMH. Three different batteries were tried with the testing on each battery performed three times as I expected the output to be higher at the led. The AA batteries used, all fully charged, were a brand new Eneloop, Turnigy LSD and an old Powercell from Jaycar. The Eneloop gave very slightly higher readings.</p><p>An XM-L LED was used for this testing.</p><p>Other drivers tested for comparison are,</p><p><a href=" HTML http://www.flashlightemporium.com/components-reviews/another-to-bring-over-and-i-promise-i-wont-edit-it/msg967/#msg967">IOS<br />Boost 1/2*AA, CR123A Circuit board review</a></p><p><a href=" HTML http://www.flashlightemporium.com/components-reviews/this-spot-is-very-lonely-please-copy-me-over-mr-mod/">Fancy<br />Flashlights AA 14500 driver</a></p>[/html] *****************************************************
