I have a recently installed 2 x 4 foot skylight installed in the east facing slope of the roof over a bedroom. I was painting in the skylight well yesterday a was surprised at how hot it was, and how hot the underside of the skylight glass was. Yes, this is Florida but the skylight was supposed to be dual-pane, low E, etc.
It appears it is dual-pane, tempered glass but I don't see any markings indicating a low-E rating.
In any case, what can I do now to let light in but limit the huge heat transfer. The skylight is very easy to get to on the outside.
