Nearly any light will do to aid in the Construction of a Monolithic Dome or other building. Many times incandescent flood lights will do the trick.
On the other hand, a good source of light can can really help with detailed work. We use high pressure sodium lights with 400 watts. Currently that is the only industrial light we are offering because we feel it is the best.
For building a Monolithic Dome a high pressure sodium light’s slightly yellow hue cuts through the fog during construction. It puts out a lot of light per watt without much heat. The glass surface is cleanable and tough.
