Technical Description & Specifications
Technical Description & Specifications
The MicroCool™ LED Examination Light is durable, attractive light designed to deliver
high quality illumination in modern hospital or clinics for examination applications. Its
design offers excellent dual brightness, color rendition, large field size and convenient
positioning with easy-grip handles. Use fixture only as intended, any other use will void
the warranty.
The fixture projects a beam of visible light practically devoid of infrared and ultraviolet
energy, but with high intensity. It provides a 7-7.5 inch spot size at a distance of 18 inches.
The light head is mounted on a spring arm system which will not sag. The light head swivels
about the arm ± 90°. The mounting system allows the light head to swing through a radius
arc of approximately 45 inches, and project a beam on any location of a human subject.
Easy grip handles at the sides of the light head assist positioning. The light head features a
cool-temperature housing.
Power is supplied through a European-harmonized grounded 8-foot SJT cord, having a
NEMA 5-15 hospital-grade North American plug. An On-Off-On switch operates the light at
The base of the light head. The light is ETL listed and made in the USA.
Specifications
The light is intended for use in the modern hospital or clinic for examination applications.
This unit has been tested and classified to UL 60601-1. The exposed metal parts that screw
on the head are not grounded, nor do they have to be, since the metal parts are adequately
isolated from the high voltage supply. All other exposed metal is grounded.
Power to the fixture is controlled from a power supply at the base of the arm, which contains
internal fuses. Effective working distance between patient and light head is from 0.2 to 0.6
meters. Two easy grip handles at the sides of the light head assist positioning. A 3-way switch
safely controls the power to the two LED modules. Users have the option to have either one
or two LED sources, power on, middle position is off.
There are no known contraindications to use this equipment.
There are no hazardous material in this product and it’s safe to dispose of after its service life.

1.2.1. Creche Innovations recommends a wall mounting height of 55-60 inches
(140-152.4 cm) from floor plane.
1.2.2. Attach the provided Wall Mount to a suitable vertical surface, it should go
into wood support that may need to be constructed. It should not be
anchored to the drywall alone.
Use four (4) #10 round-head wood screws, which are 1.5” long into wood
surfaces, or 2” long through wall board into wood studs. When attaching the
mount to the metal, use #10 round or pan-head self-tapping or machine screws,
1” long, or as indicated by the application.

Maintenance
Maintenance
2.1 Fuse Replacement
If this product is operated according to procedures in this manual, the fuses that
are located internally at the base of the transformer housing may never need
replacing. But, if one or more system abnormalities do occur, the protective current
fuse (s) will fail and need to be replaced.
NOTE: Before replacing a blown fuse(s), a complete system check should be
Undertaken to reveal the underlying cause(s) for the failure. Appropriate corrective
action should be taken to prevent future occurrences.
2.1.1. Turn the power switch off (O) and disconnect the fixture from the mains supply
to avoid electrical shock.
2.1.2. Loosen the single screw on the transformer housing where the power cord enters.
Remove cover by lifting this end up and away, it will naturally pivot around the clip
at the opposite end.
2.1.3. Check and replace fuses located on the terminal block by pulling the black fuse holder,
tab up.
2.1.4. Reverse the above procedure to restore the fixture to proper operation.
2.2 LED Replacement
Note: The LED module will outlast the life expectancy of the device (10 years) under
normal conditions and it’s therefore not needed to replace before this time period.
LED module replacement must be replaced by a Creche Innovations appointed
technician.
2.2.1. Turn the power switch off (O) and disconnect the fixture from the mains supply.
If the fixture was operating just prior to the LED failure, the heat sink is probably
to hot to handle. Allow at least 20 minutes for it to cool.
2.2.2. Remove the arm from the mount and lay it down on a flat surface, remove the four
screws on the front face of the light head and carefully separate the two halves, do
not over stress the wires from the switch to the LED module.
2.2.3. Remove the broken LED module with heat sink by first removing the four screws
around the heat sink, then disconnect the black and red wires from the LED board.
2.2.4. Insert the black and red wire into the new LED module and secure it to the housing
with the four screws from the previous step.
2.2.5. Secure the two halves of the light head. Ensure that wires are NOT being pinched.
2.2.6. Re-attach the light to the mount.

Maintenance
2.3 Preventative Maintenance Checklists
2.4 Cleaning
2.4.1. Disconnect the fixture from the mains supply.
2.4.2. Suggested cleaning technique is to use a soft cloth and mild detergent solution
in water or isopropanol 70% solution. Do not let any solution run into the
transformer housing. After cleansing, dry all surfaces promptly with a soft cloth
or towel.
2.4.3. For especially stubborn stains, rubbing or denatured alcohol can be used.
2.4.4. External surfaces are polycarbonate, or power painted. Do not use cleaning agents,
chemicals or solvents that can attack and damage polycarbonate material or stress
corrosion cracking (SCC) will occur voiding the warranty. Under no circumstances should
cleaning agents containing ester or a ketone solvents such as paint thinners, Methyl
Ethyl Ketone-(MEK) MEK, acetonitrile, acetone, ethyl acetate be used. Always check
the MSDS sheets. Use polycarbonate friendly cleaner

Check
Corrective Action
Weekly
Check overall operation of the fixture:
Do the switch and LED’s operate
properly?
Does the light head stay in position (no
drift) when the arm is moved up and
down or to the sides?
Do all components appear secure (light
head, arm attachment points)?
If the answer to any of these
questions is NO, do not use the
product. Consult with your
maintenance personnel before
operating the light.
Monthly
Check the arm to mount for “wobble.” If it
is loose…
Wall: tighten screws to wall
Annually
Check same items as for weekly and
monthly maintenance, plus inspect the
power cord for external abrasion. Lightly
pull and twist the cord at the inlet strain
relief to test for internal conductor
breakage when the light is energized.
Check electrical connectors for evidence
of overheating (charring, discoloration)
and chafed insulation.
Any flickering is indicative of an
intermittent break, and the cord
should be replaced.
Replace as necessary.
