Never touch the quartz bulb with bare hands, as fingerprints will make the glass cloudy
and cause a severe loss of light. This may also cause recrystallisation and thus
weaken the bulb material. Should the bulb be inadvertently touched, remove
fingerprints with methylated spirit and a clean, soft paper towel. The bulb should then
be wiped with distilled water. NOTE: ALWAYS WEAR MASK AND GLOVES DURING
CLEANING);
