Investigating further, the Spyder 3 appears to use the TAOS TSL238T sensors
(See <http://www.taosinc.com/productdetail.aspx?product=45>)

Given that the sensor is pretty similar to that in the Spyder 2
(Something like a TSL237S-LF - see 
and the other optics are fairly similar to the Spyder 2 LCD setup (an overall 
pass/shape filter, an opal diffuser, a Fresnel lens, then the individual sensor 
cutoff filters),
it's hard to understand why it behaves so differently at low light levels.
