Technology Associates Inc.(remembered)
The EternaLight assets of Technology Associates, Inc.
have been transfered to EternaLights, LLC. All orders and services issues will be handled by them.

In 1992, Thomas Hoops and Derone Bryson founded Technology Associates. In 1994, their partnership incorporated under the name of Technology Associates, Inc. Between 1993 and 2000, Technology Associates successfully operated a small chain of computer stores in the Reno/Sparks area which sold and serviced computers.
Technology Associates was also one of the founding investors in Great Basin Internet Services (GBIS), Northern Nevada's Largest Independent internet service provider. In 1998, TA divested itself of GBIS. In 2000, TA divested itself of it's retail stores to pursue manufacturing of the EternaLight flashlight and other related and unrelated products developed by Thomas Hoops and Derone Bryson. In 2007, the organization formerly known as Technology Associates, Inc., founded by Thomas Hoops and Derone Bryson in 1992 ceased to exist.

This site is still a functioning sales platform for the EternaLight products manufactured and sold by EternaLights, LLC. However, the remainder of the site remains as it was in it's finality before the closing of Technology Associates, Inc.

Today Mr. Bryson is privately employed as a Software Engineer. Mr. Hoops is privately employed in a manufacturing company as it's CTO. After working together since 1990, through their various projects and partnerships, Mr. Hoops and Mr. Bryson are still best friends and continue to explore new opportunities together.


Utility Light ModuleTM

Distinct features:

    The VersaLux Utility Light Module is comprised of 10 WHITE leds and power supply circuitry for use in many applications. It is the very first utility light module with the all the advantages of the WHITE LED's (long life, small size, durability, balanced color output, energy efficiency) and, our exclusive Demand Pulse Technologytm which provides additional circuitry for adjustable regulated light power output AND power consumption regulation over the broad range of its DC input voltage.

    What does this mean?
    It means that:

    • The light sources (lamps) could last up to 100,000 (11.4 years continuous - almost no bulb changes ever).
    • Flexible power source parameters. Constant, yet adjustable, light output with input voltage ranging from 2.2 to 13.8 volts dc.
    • The light output power is constant even while the battery's condition lessens or voltage varies, until it is below the operating voltage of the module (2.2 Volts DC).
    • Power consumption is conserved and regulated over the operating range where as a competitor's light may use more power at higher voltages than at lower voltages. For example, POWER = VOLTS X AMPS. The VersaLux will put out the same light level at 6 volts, consuming only .14 amps thus only .84 watts, as it will at 12 volts, consuming only .07 amps thus still only .84 watts. However a competitor's unit, even if capable of operating over such a broad voltage range, may consume .14 amps at 6 volts (thus .84 watts) and still consume .14 amps at 12 volts thus 1.68 watts.
    • It's compact form is only 1.18 inches tall by 1.95 inches wide by 1.2 inches thick.
    • It's 10 LEDs of strong white light output.
    • The lighting pattern is a 20 degree flood pattern without reflectors or diffusers.
    • Constant light output is adjustable via onboard potentiometer from 0% to 100% of total power output.

    So what can I do with this?
    You can:

    • Make small, lightweight, powerful, long battery life head lamps (to wear on helmets, ball caps or hand straps).
    • Add long life, energy efficient lighting to you Mobile Home, RV, car, remote area or room.
    • Construct lighting systems which are powered by low voltages over a wide range. For example, here are some typical power sources and performance estimates:
      Highest output
      life (hours)
      Low output(15%)
      life (hours)
      (1) 9 Volt Alkaline4 + 40 +
      (3) AA Alkaline (series)7 + 95 +
      (4) AA Alkaline (series)11 + 120 +
      (4) D Alkaline (series)110 + 770 +
      (4) AAA Alkaline (series)6 + 48 +
      (4) AA NiMH (series)9 + 64 +
      b(4) C NiMH (series)12 + 87 +

    • Retrofit existing flashlights and lighting systems to reduce power consumption, increase longevity and produce white light. [CLICK] here for examples.
