The Lambda Micro Illuminator is a custom modification of a Brinkmann Legend 1x AAA flashlight, modified by Lambda of Candlepower Forums. Inside the flashlight's head is what I believe is a HD (high dome) Luxeon Star LED emitter, and a DC-DC inverter "pill", powered by a single standard AAA cell. The LS LED is focused by the flashlight's reflector, and is protected by a replaceable glass lens.


The Lambda Micro Illuminator came to me ready to roll; yours probably will too. If yours did not come with a cell installed, install it first (see below) and then you'll be ready to go.

To use the Lambda Micro Illuminator, press lightly on the tailcap to turn the light on in momentary mode; hold it that way to keep the light on for as long as you hold it. To shut the Micro Illuminator off, simply release the tailcap, and your light should go off.

For continuous mode, press the tailcap more firmly until it clicks; the flashlight will then stay on without further intervention from you. Press the tailcap the same way until it clicks again to turn the light off.

The flashlight has a LOTC (Lock Out TailCap) function. This prevents the light from turning on by itself when the switch is inadvertently pressed, such as when it is packed in a box or camping kit. To use this function, first be sure the flashlight is turned off. Then, turn the black plastic portion of the tailcap clockwise (as if tightening it) approximately 1/8 of a turn until it clicks into place. To disengage the LOTC function, turn the tailcap counterclockwise (as if loosening it) approximately 1/8 of a turn until it clicks. Then you can use your Micro Illuminator normally.

The Micro Illuminator uses a single AAA cell; this was already installed in the sample I received.

To change the battery, unscrew the tailpiece and throw it away - OH WAIT, YOU'LL NEED THAT!!! So just set it aside instead. ;-) Tip the dead AAA cell out of the barrel, and dispose of or recycle it as you see fit. Insert a new AAA cell into the barrel, button (+) end first, then screw the tailpiece back on. Aren't you glad you didn't throw that tailpiece away now? ;-)

I received the Micro Illuminator on 01-31-04 around 7:55am, and I just started writing the page this evening (02-25-04) so I don't have any information here yet.

From the Micro Illuminator web page: The Micro Illuminator uses the new EOS process Luxeon LED for bright, smooth light output that maintains it's color tint from the center of the beam to the edge of the corona.

Beam photograph at ~12".
Measures 135,300mcd on a Meterman LM631 light meter.

Color temperature is a pure white, coming in at around 6450K.
This light has a nice white color, with no yellow, blue, or "rotten rat urine green" to it.

Test units of the Micro Illuminator and three other Lambda mods were received on 01-31-04
It came with one AAA cell already installed, and at least several replacements wrapped seperately. It also came with a small "adapter" that you install between the tailcap and barrel, and a medium sized split ring that you can affix to this adapter. So you can carry the Micro Illuminator on a keychain if you wish.

Please visit the website and ask Lambda (Kevin Fritz) about ordering these flashlights. I just review flashlights here; I do not sell them.

UPDATE: 00-00-00



    Light is of a homemade nature and will not be rated like a commercial flashlight.
