Excellent manual on GE lamps including Halogen, Compact Fluorescent, High Intensity Discharge and some standard incandescent. Somewhat dated but much good date. Angle/intensity curves, Lumen/Life/Voltage/Current curves (Jinx will be fascinated), ... Typically 10% voltage reduction from rated gives 69% of full rated Lumens but increases lifetime to 350% of standard. ----- Original Message ----- From: "Ken Mardle" > Russell, > A very comprehensive (133 page) technical manual covering GE's lamp > range. > Get it while it's hot :-) > http://www.ladyada.net/make/bikelite/datasheets/GEhalogenstech.pdf > > Date suggests it could be quite old (1996). -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
