left by fingerprints will seriously degrade a
lamp's performance or cause "hotspots",

intense heat in the touched area and cause
the lamp to shatter. Clean the glass exit

absolutely necessary.

used in the RPMSP-D275U model since it
does not have a glass front.

surface of the glass in a circular motion
