Recommendations for mounting Celestial Star MRI ceiling (for hard ceiling to drop
ceiling distance greater than 5 feet)
When using a set up shown in figure 6: If the drop ceiling to hard ceiling distance is 3 feet or less than 3 feet,
then one horizontal plate is recommended. If this distance is more than 5 feet then use of another horizontal
plate above the first horizontal plate is recommended for assuring stability of the structure and stability of the
light.
On the horizontal plate shown in figure 6, 4 holes can be drilled for mounting the L-bracket. More than 4
holes can also be drilled on the horizontal plate to assist in mounting the light at a proper location.
• Maximum load of the light is 50 lbs.
• Moment of assembly, balance arm extended horizontal outwards, (29” [74cm] long extension
arm) = 50 lbs X 57 inches = 2,850 lbs.inches (322 Newton.m)
• Moment of assembly , balance arm extended horizontal outwards, (39” [100cm] long
extension arm) = 50 lbs X 67 inches = 3,350 lbs.inches (379 Newton.m)
• If the longer extension arm (39”/100cm) is used, then the lamp head extended horizontally
inwards will not reach the same point that the 29”/74cm arm will reach.
MOUNTING NON-MAGNETIC STAINLESS STEEL PLATES FOR INSTALLING THE LIGHT
(RECOMMENDATIONS)
CAUTION! Non-magnetic materials should be used in the MRI environment. Consult with
your MRI facility manager if uncertain.
1. Non-magnetic stainless steel: Flat horizontal plate, minimum 3/8” (10mm) thick, length of the plate
to be determined by the contractor (Recommended dimensions: 63”LX6”W/160cm LX16cm W).
2. Non-magnetic stainless steel: 4 L-plates for supporting flat plate and stability of the light, minimum
3/8” (10mm) thick, length of the plate to be determined by the contractor.
3. Non-magnetic stainless steel: L-bracket, minimum 3/8” (10mm) thick, dimensions of the bracket to
be determined by the contractor. (Recommended dimensions: 12”L1X8”L2X6”D/31cm L1X21cm
L2X16cm D).
4. Non-magnetic stainless steel: side plates for extra support for L-bracket, minimum 3/8” (10mm)
thick, dimensions of the bracket to be determined by the contractor. (Recommended dimensions:
4”X4”X3/8”/11cmX11cmX1cm).
