I got them today, unpacked and started poking at them:
The lamp replacement method is awesome.
The locking focus adjustment is great.
It's a Source Four! OMGBBQ!!11!
They are light and seem sturdy.
I'm going to need a spare bag of the spring retaining clips immediately. Just opening them and closing them once has bent 3 of the clips, requiring rather a lot of fidgeting to get the gel frame door shut. Is this really the best method?
The gel frame door is no longer a one-handed operation, making us ladder-dwellers sad. Sadface.
I'll connector them up today and turn them on. More reports later!
