Preferably keep a fan blowing over your artwork & PCB. The lamp produces a
lot of heat- 500W.
I am literarily using lamps like that for a specialized heater to melt
plastic. 9 of them mounted side by side in a 3x3 array. 4.5kW!

The floodlight is a yellow aluminium device with a glass cover and a
steel frame for sitting on the ground. It is intended for building
sites and the like. I took the glass cover off and used it for other
purposes. This may slightly improve the UV output, but the main reason
I did so was because I have mine shining downwards and I wanted to
improve air flow around the lamp. I left the wire frame safety guard in
place, so it is unlikely that I or anyone else is going to stick their
fingers into it while it is turned on.
I think these are produced in vast numbers in China, so the same
products are likely to be available in most countries, for instance:

I paid Australian $16 for mine at the nearby hardware store. These
floodlighs use a small tubular filament lamp 119mm long, such as:

There's no ballast, since it is not a gas discharge tube.
