12 feet from target, on high, with three D-sized 12000mAH NiMH batteries
This 3D MagLite was modified by Nailbender, and has a d2Flex PWM driver to adjust brightness and runs for a VERY long time with this battery setup, even on high. It has a light orange-peel reflector. The DSVNI-binned P7 has very nice "buttery" tint.
This was taken a day late. I didn't take a picture at all the day before, so I took a bunch today to make up for it.
The massive rock in the top 1/3 of the image is the Hartselle Formation. The eroded, dissolved, and narrow, fluted Monteagle Limestone is seen in the lower part of the image. Both are Mississippian in geologic age. Caver in the background for scale.

The forward-facing, narrow-angle beam uses 5 ultra-bright, 5mm white LEDs, and the downward-facing wide-angle beam uses 3 - and together these light sources enable you to feel safer while walking in the dark. There are multiple lighting options available with the flashlight’s 3-way switch: the front light alone, both front and lower lights, and lower lights only.
Each of these shots contains a Gretag-Macbeth Color Checker classic (http://www.xrite.com/product_overview.aspx?ID=820) which is "an array of 24 scientifically prepared natural, chromatic, primary and gray scale colored squares in a wide range of colors. Many of the squares represent natural objects, such as human skin, foliage and blue sky. Since they exemplify the color of their counterparts and reflect light the same way in all parts of the visible spectrum, the squares will match the colors of representative sample natural objects under any illumination, and with any color reproduction process."
I'd been wanting to try some time-exposures of flashlights for some time. This example comes from a night of collaboration with Cyndi and Keisha. The three of us are walking away from the camera, moving our flashlights up & down.
I LOVE LED flashlights. Soooo much brightness in such a tiny package.

12 feet from target, on high, with white-top AA Duracell rechargeable ("Duraloop") low-self discharge NiMH battery
High on the success of getting the switch working, I decided to press on.
Next up, I soldered the 6V bulb to the leads: Another continuity/resistance test, and still looking good - Hey "test as you go" works wonders if you can mange it.
