Still in the process to design my DIY video light...Thanks to this forum things are going on, I think that I finally choose how to do a couple of things:
The driver will be a Taskled H6Flex driving 6 XML (3s2p), it's able to give them up to 3A that is the max current for them. The point is that with just 4 li-ion cells may be I'll need to lower a bit the current to have a decent runtime.
I'm drawing the components of the head and got this:
I'm planning to use a thin glass lens reinforced by the one-piece diffuser that its in contact with the heat-sink.
The idea is that heat will heat-sink also through the glass while being "supported" by the diffuser.
