Turns out Lighting Plus in Auckland sell ‘daylight bulbs’ that fit a normal household socket for $8NZ each and as Steve points out below they are indeed blue. Picked up a couple this afternoon as well as a ‘hobby light’ (light / magnifier combo) that they had on sale for $30NZ.
The Mordheim canal tiles are slowly progressing through various stages of drybrushing. I’ve also finished the experimental water feature but I’m not entirely happy with it. I might have to go with some decent resin water effect for the tiles – which means finding a cheap source of clear encapsulating resin in Auckland somewhere.
