After reading this www.diyphotography.net/ikea-continuous-light-ring-flash I decided to build my own.
This is version 4. Version 3 caught fire - oops - and was my first attempt to snood the light. This thing kicks out a huge amount of heat!
Version 2 is below. Version 1 is just like 2, only without the orange lamp added to "gel" the pictures.
It's made out of a Target HulaHoop, some wire coat hangers, lots of black card, 12x 60W bulbs, and an orange mood light. It has two power cords (to control different lights).
