Although I installed new lighting above our track and staggered it for good effect, I still needed more light at times.
I asked two of the best photogs I know - Dave Kennedy and James Simpson.
The answer is cheap and easy.

These are cheap little drop lights you have seen for years. They are pennies in cost compared to "real" photog lamps and they REALLY WORK.

Pics in my reviews/articles are not the greatest...still have to be smarter than the equipment you are trying to use :)
But I never have to use a flash.
This lamp helps a great deal.
