I work with a preformance arts company doing shows in the scottish highlands and due to the massive amount of rain fall we need to use water-prof lighting.
We have been using 12v hallogens with some success but I cant find any pre-built 12v dimmers. I have found several that use 240v dimmers and then drop the voltage down to 12v but none so far that start with a 12v input.
My limited understanding of switch mode power suplys makes them seem like the logical solution but I dont know enough to pick the right chip.
I have found some that require only couple of external componets and only a small heat sink.
If someone could point me in the right direction it would save me a great deal of heart ache.
Thank you for your time. Nik
