Relative light output
Timer mode
When first powered on, eternaLight will light up with full power but will shut itself down gradually. Each of the four lights will extinguish
approximately every 2 minutes in succession. During this period, you will see the internal NightBeacon lamp blinking every second.
When all lights are finally extinguished, the internal NightBeacon lamp lights full on for 1 minute then the unit shuts off. While in this
mode, pressing the:
•(Power) button will turn the unit Off.
•(Mode) button will advance to the On/Dim mode.
•(Adjust) button will select a lower power level. Once a lower power level has been selected, the lights will not go off in succession,
rather, once the time has expired, all lights will go off and the internal NightBeacon will light for 60 seconds then the unit will turn off.
On/Dim mode
This mode is capable of delivering incredible battery longevity (see Eternalight Secret Revealed on the last page). Upon entering this
mode, the unit will light up with full power (maximum light output). While in this mode, the unit will stay on until it is manually turned off
(unlike the timer mode). While in this mode,
pressing the:
•(Power) button will turn the unit Off.
•(Mode) button will advance to the Flasher mode.
•(Adjust) button will select a different power level. Every time this button is clicked, the unit will produce less light until, it has reached
the lowest level. If clicked again on the lowest level, it cycles around to the highest again. There are a total of 11 power levels and 12
(Adjust) clicks to access them. Also, note that while most of each of the levels consume less power sequentially, the last level
consumes more. Pressing and releasing the (Adjust) button each time will step the power down to the next level. The chart below
shows the battery performance expectations from the various power levels.

*Calculated with fresh alkaline batteries of 2850mah capacity.
Assumes running continuously with light not falling below 20%
of fresh battery output. Lithium battery performance will be
even better at the higher output levels.
**Regulation must be disabled in the configuration (see “off”
features later).
Regulated versus Unregulated performance:
Regulation maintains constant light output regardless of
battery condition until the batteries are almost completely
exhausted. The graph to the right demonstrates the effects.
NOTE! In daylight, the “strobing effect” of the lower power
settings may appear too obvious and not usable. This is NOT
true! This timing is set for the way your eyes function in the
darkness. Judging your eternaLight’s effectiveness in light
conditions will not give you a proper idea of how well it
functions in the dark.
Flasher mode
Upon entering this mode, the unit will simultaneously flash all four lamps. While in this mode, pressing the:
•(Power) button will turn the unit Off.
•(Mode) button will advance to the Strobe mode.
•(Adjust) button will select a different flashing time. There 16 different strobe rates from about 4 flashes per second to about 1 flash
every 3 seconds. “Clicking” the (Adjust) button selects the next rate. Clicking at the slowest will start back at the fastest rate again.
Strobe mode
Upon entering this mode, the light will appear to glimmer. It’s actually flashing very fast. This mode is similar to the Flasher mode above
but much faster and with many more rate settings than the Flasher mode. You may point the light at a repetitive moving object like a fan
and adjust the flashing rate by holding the (Adjust) button down until the object appears to be standing still. While in this mode, pressing
the:
•(Power) button will turn the unit Off.
•(Mode) button will advance to the Dazzle mode.
•(Adjust) button and holding will increase the strobe rate from about 30Hz to about 1.5Khz. The timing is not precise and is only meant to
visually inspect a repetitive moving object, not to determine it’s speed.
Dazzle mode
Upon entering this mode, the unit will flash each bulb in an attention-getting pattern. While in this mode, pressing the:
•(Power) button will turn the unit Off.
•(Mode) button will advance to the S.O.S. mode.
•(Adjust) button has no effect.
S.O.S. mode
Upon entering this mode, the unit will flash the Morse Code sequence S - O - S (Save Our Ship), an old maritime distress message for
requesting emergency help. See Figure 2 above for other Morse codes. You may send Morse code yourself by using the Momentary
function discussed later. While in this mode, pressing the:
•(Power) button will turn the unit Off.
•(Mode) button will advance to the On/Dim mode.
•(Adjust) button has no effect.
Pulse mode
Upon entering this mode, the unit will fire all 4 bulbs at OVERDRIVE level then fade out, blip the night beacon and repeat. This is a high
energy signalling mode. Thus, it will consume batteries rapidly. About 24 hours of continuous use can be expected in this mode with
fresh Energizer or Duracell alkaline batteries. Pressing the:
•(Power) button will turn the unit Off.
•(Mode) button will return to the Timer mode.
•(Adjust) button has no effect.
“Off” Features
Off features are features or functions which you can access while the eternalight is turned OFF.
•Momentary Overdrive: This feature may be activated simply by depressing the (Adjust) button while the unit is off. The brightest light
possible will be emitted while the button is held down. This may be used for signalling or for quick spotting. It is not recommended to
leave this on for more than a minute at a time due to heat buildup.
•NightBeacon(tm) Feature On/Off: Unlike the previous modes, NightBeacon is a feature that once activated, remains activated
regardless of the mode you are in. NightBeacon(tm) is intended to allow you to find the unit in dark conditions after you have turned it off.
Inside the unit is an internal LED that will either Blip once every 2 seconds or Glow, depending on how NightBeacon is configured (see
configuration mode below). This feature will operate every time you turn the light Off. To activate the Night Beacon Feature, while off,
simply press and hold the (Adjust) button while pressing and releasing the (Power) button. The unit will turn off but you will notice that
once every 2 seconds the internal LED will briefly flash. This mode should be able to operate continuously on the same batteries for 1.5 to
2.5 years. Therefore, it is not recommended that you leave this mode enabled if you intend on storing the light indefinitely. The Glow
mode will run steady for between 1 and 2 years. To deactivate the NightBeacon(tm) feature, while the unit is powered off, perform the
same operation.
•Battery Test:
To test the batteries, press and hold the (Adjust) button. While the adjust button is held, press and release the (Mode) button, then
release the adjust button. All lights will come on for about 5 seconds. After that, the battery status will flash four times then turn off. 4
LEDs good, 1 LED bad. Below is a more precise meaning of the status:

•Configuration Mode: To enter the configuration mode, while off, hold the (Mode) button down for three seconds. When the
configuration mode is activated, the all lights will glimmer except one. The steady light is the configuration feature. The sticker on the
back of the EliteMax denotes which feature is selected by the lamp position. Pressing the (Adjust) button will enable or disable the
feature. Pressing the (Mode) button will advance to the next feature. Note: there are 5 features, the 5th is indicated by the NightBeacon
lamp internally. Note: The (Power) button has no effect in this feature. The only way to end it is to keep pressing the mode button and
cycle through all settings. See the chart below:

•Reset: resets the unit to default configuration. The reset the unit, while off, press and hold the (Adjust) button, then press and hold the
(Mode) button then press and release (Power). Alternatively, remove the batteries, then press and hold the (Power) button for 10
seconds.
Replacing batteries & maintenance:
When eternaLight does FINALLY need new batteries, it may not operate properly or the brightness from lamp to lamp may vary greatly.
The functions well on a variety of batteries. Nickel Cadmium, Nickel Metal Hydride, Alkaline and Lithium L91 type batteries, and all other
chemistries that are between 1 and 1.7 volts per cell in AA size are usable.
To replace the batteries:
1. On the side opposite the switches, remove the four screws with a standard phillips screwdriver.
2. Remove the back cover be careful to not lose any screws. EternaLight will not remain water resistant if fewer than four screws
are used when reassembling it.
3. Note the polarity (+ and - orientation) of the batteries and carefully remove them.
CAUTION! Lamps are powerful enough to cause damage to the
human eye. DO NOT STARE directly into lights.
WARNING! Installing the batteries
incorrectly can permanently damage your light.
WARNING! Magnet on back of light may cause erasure to
magnetic media if media’s proximity is less than 2 inches.
NOTE! It is normal for the tint of color and brightness to vary
slightly from lamp to lamp. This is NO indication of failure or
malfunction.
NOTE! Unit is NOT intended to be used as a dive light. Water
pressure on buttons may prevent user from controlling functions at
depths below 8 feet.
NOTE! Use of Alkaline batteries will not damage unit but are too
heavy for unit to float.
