DIY Dental headlight (Need some input please)

Hi all.

I have been playing around with this idea for ages and have decided to try and do this from various sources posted around the net.

I was originally interested in this project posted from CPF and I have used to get most of
the items for a basic setup. I am still waiting for the items to arrive and will post some pics hopefully as I get everything together but I have realised
that the driver that was chosen originally may be a bit big and cumbersome to try and fit nicely into the overall setup. This driver I’ve ordered so far is this one which is dimmable and is a must of a feature I think personally. I am of course very noob-ish with all this and would greatly appreciate some input into maybe something smaller that I could perhaps mount inside the body itself…?

I am honestly not sure.

Thanks…!
