Macro Photography LED Ring Light with dimmer

This is a Macro Photography LED Ring Light that has a built-in variable brightness dimmer. I've been enjoying it for a while now so I thought there might be some macro photographers out there who would like it too. It's based around a 12 volt led ring light that you see fitted around some modern car headlights like the ones on Audi's. It's inexpensive to make and the results are good! It's also good as a soft fill light for close up beauty shots and gives a nice reflection in the models eyes. It works for close up foodie shots too :)
It fits from a 60mm up to a 85mm diameter macro lens.
The battery life is under an hour but if you don't leave it on when you're not using it you can get a lot of use out of it... better still, use rechargeables.
All the parts have eBay and other links in the post printing section below.
