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.
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.
eternaLight Elite Series Statement of Water Tightness
(last updated 1/29/02)
The statements and test results below are only
for informational purposes and not to imply any sort of warranty or
standard of performance.
The eternaLight EliteXRay model 4X is only said to be "water resistant".
Meaning that if the unit is accidentally immersed in water for a short
period of time, the unit will likely continue to function without fault.
This being said, below are the results of actual tests which far exceed
the statement above, keep in mind that the eternaLight is not meant to
be a diving light.
On January 10th, 2002, two randomly selected production model Elite
XRays were taken to
(Ameriquest, Inc.) for depth pressure testing. Ameriquest Inc. is a
leading manufacturer of under-water enclosures for video cameras. Dale
Peronteau, president of Ameriquest, conducted the following tests himself
in a wet pressure chamber which simulates the pressures of water at depth.
The first unit was taken to a depth of approximately 120 feet.
At that depth, there was enough pressure to activate the switches on the
eternaLight, causing it to come on or behave strangely since all
buttons are being depressed simultaneously.
However, there is no apparent lasting ill side effect from this
and after disassembly, the unit did not show any evidence of leaking.
*Note: Depressing all switches at once will not harm eternaLight or
shorten its life.
The same unit was then taken to a depth of about 230 feet for a period
of 5 minutes. After removal from the tank and upon inspection, a small
droplet of water could be seen in the bottom corner of the unit. No
other damage or penetration had occurred. 230 feet was the maximum
pressure the tank was safely rated for. The depth at which implosion
or other damage may occur is unknown.
- The second unit had been severely abused (four 50 foot drops, rolled over
by a truck on pavement, three 12 foot drops onto concrete). This unit
was taken to a depth of 60 feet for 1 minute. When removed from the
tank, it showed no signs of leakage or malfunction.
As further testing occurs, this page may be updated.
The eternaLight Model 4X EliteXRay is only as water resistant as the
perfection of its last assembly. There is no "per unit" test in this
area, such would be extraordinarly expensive and would be meaningless
once the unit were dismantled for any reason like a battery change.
Because of this, if you intend to use your unit
in an environment which will subject it frequently to immersion, we
suggest that you dismantle and inspect your unit often. Be sure there is
no debris or defects on the gasket or the perimeter and seal line. Be
sure the unit is assembled securely. Be sure you have applied an even
torque to each screw. Check your light frequently for any moisture
build up inside. If such is found let the unit air-dry for 12 hours or
more before assembling. Such build up can cause corrosion and damage
Be aware that use of Alkaline batteries will not damage the unit but
will make it too heavy to float.
