Without counting the models with heated front glass, there are 33 different models of these new cameras. Here I'm breaking down the minimum illumination and LED lighting specs.
Keying off the model numbers, there are logically 3 camera series:
PRO - 4, 6, 8 megapixel models, all with 4 LEDs.
IL-T (T does not mean turret) - 4, 5, 8 megapixel models, bullets have 4 LEDs, turrets 2 LEDs
IL-E - 4, 5, 8 megapixel models, fixed focal bullet only, 2 LEDs, smaller cases than T series bullets
PRO series, Minimum Illumination spec color/B-W
Fixed focal 4MP 0.0004/0.0003
Fixed focal 6MP 0.0005/0.0003
Fixed focal 8MP 0.0005/0.0003
Standard zoom all models 0.0006/0.0003

There were a few data sheet inconsistencies that looked like errors to me, which I "corrected". Check the official data sheets before making model decisions!
