[RASMB] UV lamp for XL-I

[Tom Laue]

Hi-
The Hamamatsu lamp is _not_ obsolete, but it is costly and has a long 
delivery time. You will not save much money and could gain a lot of 
aggravation buying your own.
You have to be careful about matching the lamp, socket and power supply 
in order to get a flash that has the correct times (delay, jitter, 
intensity, rise and decay). Once upon a time Beckman had a "hand-select" 
process for these (and for their PMTs which are also Hamamatsu).
Best wishes,
Tom
