eternaLight Features
Congratulations! You’re holding the first ever flashlight of this type. eternaLight uses a solid state light source (white
LED) which has much more durability and a much longer life than a standard flashlight bulb. Each of the four white
LEDs is rated at 50,000 hours or more of continuous use compared with 40 hours or less from a typical flashlight bulb.
The solid state bulbs will always produce the “fresh-battery” moonlight-white light, even when your batteries are nearly
dead, unlike a typical bulb which will gradually yellow.
Depending on your power (
Dimmer setting) use, a standard set of three AA alkaline batteries will continuously produce
light from 48 hours to well over 700 hours (actual testing beyond this limit has not occurred, but projections indicate
continuous operating time could hit 1400 hours!). If you purchase lithium AA batteries to use in your eternaLight, this
performance will be even better and the shelf life could be over 10 years!
The eternaLight Secret revealed - bolt on your brain caps!
eternaLight’s secret to its long battery life is in the white LEDs it uses AND the microprocessor’s ability to control power
to them. The LEDS are fairly efficient by themselves and capable of delivering over 48 hours of continuous usage at full
power before their output drops below 40% of the fresh battery output. However, in the On/Dimmable mode, the
microprocessor really takes over and energy savings become obvious. The first conservation setting is barely dimmer
than the maximum power setting yet only consumes 65% as much power! The next setting consumes roughly only 33%
as much and so on. Finally, the lowest setting only consumes 1.7% of the power used in the maximum setting yet still
produces a very usable amount of light - enough to walk or read with! The microprocessor accomplishes this by pulsing
the energy to the light sources within average optic nerve response time. Since the spectral output of the LEDs remains
fairly constant, these pulse timings can vary greatly yet still produce usable light.
But wait, there’s more...!
Because eternaLight uses a microprocessor, it can provide different modes of operation which may have different
applications. The Timer mode will save your batteries if you accidentally turn on the light. The Flasher mode is useful
for signaling, emergency, safety or attention-getting purposes. The Strobe mode is useful for “freezing” an object which
is in a regular cyclic motion such as a fan blade or an engine pulley. The Dazzle mode is useful for sales attractions,
presentations, costumes or just to look cool! The S.O.S. mode can signal for help and the Momentary mode allows you
to send your own code. For more eternaLight information, be sure to see our website at www.TECHASS.com.

2. Remove the back cover be careful to not loose 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.
4. Place the new batteries in with the same polarity. YOUR REPLACEMENT BATTERIES MUST BE
LITHIUM L91 TYPE FOR THE UNIT TO FLOAT! The unit will turn on when the batteries are placed
in it. Don’t worry, you can turn it off after you reassemble the unit. Be sure the gasket is
properly placed around the perimeter of the case and that the screw holes are lined up.
5. Holding the unit with its keypad against your palm in one hand, place the cover with the
screws back on with the other hand. BE CAREFUL to make sure the screws pass through the
gasket, otherwise you may tear it! Squeezing the top together (side with lights) tighten the top
two screws. Then tighten the bottom two screws. Make one more pass over all the screws to
assure maximal tightness without stripping the screws. Turn off the unit.
If eternaLight ever becomes DAMP on the inside for whatever reason, remove the batteries immediately and
allow the unit to air dry for 24 hours.
