I have tried some desk lamps, Dave, but I've found the halogen globes not strong enough. And I don't like the colour of the light. My problem at home is if I want to take photos at night, the overhead lights cast too many shadows. So I was thinking of reasonably powerful lights to drown out the unwanted shadows. During the day, I have a corner of north facing windows for fairly even light and I use the tripod.
What sort of globes and wattage would be a minimum starting point?
How can you run out of PAD ideas when you live in an exotic location?
