incandescent bulbs can be controlled with a
dimmer switch found in a hardware store
Technically, those hardware store dimmers unless
fed in the normal way with wiring and mounted to the wall also are very specifically against code to use. Don't tell anyone but it's a common practice to break this part of the code and even not listen to the cooling fins where a box with ventilation is involved.
This said, such use is industry, yours is not. You do need to follow code much less are not trained yet in making stuff more safe than hack. Most in the industy are not even trained or put a second thought into such things beyond being hack either. Stuff like 1900 boxes (normal wall boxes) with the
cord strain reliefs loose, or knockout holes either missing or bent in amongst loose screws and other problems. A crappy little lighting company taught me a better way such as in using outdoor boxes, weather tight strain reliefs, and outdoor covers on the operation so as to produce a product that is very safe to handle. Even to the
point on 2Kw dimmers to the
point of mounting brackets over the knob to protect the
dimmer from impacts. Costs money to do such things. 99% of all household dimmers in the industry are both against code and also blown out in having been overloaded. Overcurrent protection of the equipment also having been something missed in adaption of these dimmers to application.
Instead I expect that given the mass amounts of keys available to you, that sneaking into the science lab and borrowing the variable resistance dimmers would be a better plan and also many times more accurate in what
intensity you desire them to be at. (This was more joke than reality.) More realistically, you might even be able to coordinate with them to store such things for them in us as opposed to sitting on the shelf for the once a year demo. Such dimmers are also very acceptable for the purpose you intend. Such variable resistance
dimmer packs are normally rated at 1,000 Watts and should have pleanty of
power to do run lights.
