Hi all!!

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.

I'm choosing glass as I got the idea the transmittance index is better than polycarbonate and is more scratch resistant. I'm thinking on something like that:

The seal is obtained by screwing the heat-sink into the head and with an o-ring between the lens and the recess in the head. I think the picture is quite well self explanatory.

Waiting for your comments, may be I'm not in the right pad, it's my first try so please be indulgent with me.
