Hey Jim, essentially you have to install multiple illuminators in a circle around the mounting location, or a semi-circle if it's a 180 degree panoramic. Raytec makes a model that covers 180 degrees.
You could also use individual illuminators, 90 or 120 degree pattern, to cover the area you need to.
That 180 IR illuminator is ~$3,000 online. And three times the size of most panoramic minidomes. I am not even sure how you would mount it and not block the lens of the panoramic camera.
That said, it's a very interesting question because (1) these cameras are generally poor in low light and (2) I am not aware of any that have built in IR, which is probably hard to design (to match the wide FoV).
I have used cheaper 90 degrees China made and it has worked fine outdoor for the past 2 years. These are not like the cheap knock off external IR for analog type.
Their designed is not as good as Raytech and the range/distance is discounted (never really measure it, installed the 100 meter version and looks fine at 50 meter) but also at discounted price compared to Raytech.
They have alternative what LED (Osram, etc) you want there are 5 or 10 years warranty depends on the LED I think.
Here's something that claims to be 360 - a low cost, indoor type unit.
One other potential hurdle - a lot of these panoramic cameras are color only and likely filter IR light, which will be a show stopper for them.
What i am thinking is using 4 IR projector units to surround fisheye dome. But the projection angel is hard to define. It will cause the lighting condition of each dome is unique, different from each other.
Another question to ask is "Does the camera have an IR cut filter?" IR cut filters are used to block the infrared light that is present in daylight to improve the color.
Infrared illuminators are worthless if the cut filter blocks it.
Of course it has mechanical IR cut filter for day/night mode even no infrared illuminators.

As an economic solution, I recommend Redbeam IRD120 that is around 70 Euros.
I just spotted this 360dgr camera with built in IR leds, suitable for outdoor.
Never tested it, however...
PXD-5362F01IR, around €800,- MSRP (about USD1100,-?)
