Many brands for years now package lamps differently in an ever changing type of thing. I have never seen the gloves packaged with a lamp but am familiar with the foam or bags for the lamps.
First the spare lamp has to get to the
fixture in say dropping or shipping by way of breaking. Than yes, how to install the lamp if you don't have alcohol pads provided or on
hand to clean it - even if you were careful in not touching it. Some brands of lamp package boxes won't survive the
drop test. Some boxes are more mold resistant also when they get damp.
Sometimes bags get left on the lamp - seen that a few times, or even the foam falls into the
reflector area - and just kind of left in there somehow. Seen that also at least once. But those are the better options for doing the lamp install assuming the box protects the lamp suffient to get to the
fixture in getting dropped.
Yes I pay more for lamps with better packaging and even consider how it's installed and you are correct to do so also. But on-site, everyone shoud be able to clean the lamp upon install for the just in case.
Denatured alcohol in a spray
bottle and clean room wipes, Brawny lint free towels,
lens cleaning wipes, isopropal alcohol wipes from a first aid kit, or extra wipes from moving light lamps - even if old and dry given a sprayer should always be on
hand to clean.
A good training concept for those changing the lamps is to instruct in how to change the lamp, completely touch that lamp in explain of not to do so - and by the way this lamp is now dirty. Than provide the materials and training in cleaning the lamp. This way it's not assumed something out of a box is cleaned, and cleaning the lamp does get done properly and with training.
