We're down to about 1m2, I've got masses of white of course.
The front of these lights where the "glass" is don't really get very warm, the heat is all on the back (it's a crappy heatsink, hence the COBs not lasting 1,000,000 hours).
In the current torrent the unit is also being water-cooled!!!
With my luck we'll get a lightning hit that will fry it anyway 😞
