The 1252 bulb is a simple mixture of halide additives from the 1251 and
1262 bulbs. The 1262 spectrum looks exaggerated, because it is vertically
exaggerated. If you plot the three spectrum using the same vertical
scale, , the 1262 spectrum will look like the 1252 spectrum without the two
humps at 400 and 420 nm (caused by the 1251 additives).
By the way, the spectrum of the theimer violux bulb is nearly identical
to the 1252 bulb. So much for trade secrets.... Ed.
