These are Black Type III Hard Anodized finish. They are fully potted and use the same reflector as the M61 for a good balance of throw and spill.  The LED is a White (5700K) Luminous SST-20 or a Neutral White (4000K) 95 CRI Luminous SST-20. 

This light will support standard alkaline AA, lithium primary AA, and rechargeable NIMH AA.

Mode of Operation:

The switch debounce time is 150 milliseconds. The mode will advance each time the light is momentarily activated and the switch debounce time has passed.

This light uses ON time to determine mode switching.  If the light is left ON for more than 1 second, the NEXT off/on cycle will return the light to low.  If the light is NOT LEFT  ON for 1+ seconds the next off/on cycle will advance the mode.  The off time has no relation to the mode switchingof the light.  In most normal use, the light will always come on in low.

Summary of Modes at 1.2v-1.5v: 0.3 lumens/9 lumens/115 lumens (Cool)

                                                        0.3 lumens/8 lumens/90 lumens (Neutral)

Runtimes will depend on capacity of batteries used. In general capacity/draw * 0.80 or {[mah battery/draw]*0.80}=approx runtime in hours.

Approx Draw by mode:

LowLow = 8ma

Low = 90ma

High = 1500ma

A 2000 mah Eneloop at full charge will provide approximately 200+ hrs on LowLow, 18+ hrs on Low, and 1 hr on High.


Length: 4.5 inches

Diameter: 1 inch (head)
