I finally got sick of how dodgy my old lighting setup in the back room was and ordered a proper one, which arrived today!
With the old one it was a bit cramped at the right because where the "arm" was is around where the airbrush sits, with this I can attach it all the way at the left edge of the table and it reaches out nicely. My only complaints about the new one are that 2200 lumens is actually not as bright as I thought it was, and the LEDs in this are quite blue compared to the old switchable light. It's not a big deal though because I'm not doing any colour-critical airbrushing, I can pretty much count on the fingers of one hand the number of times I've done anything except black and white.
