Fortunately it wasn't the TS that dropped, that would have burnt me, the SP though was fine, that's the point. The cooling on the SP , so long as I only touched the black outer case was fine to handle. Just some area at least on a TS case that allows it to be held while on, could be a really handy (sorry realised the pun after typing), feature to add.
Very interested to hear about the alterations already planned though.
Our power supply shell has a grounding wire, and the lamp shell is grounded through the contact between the power shell and the lamp shell. Therefore, it is recommended to install the power supply on the lamp housing. If the driver must be out of tent. The grouded socket can avoid this situation.
