I am enclosing some data I have taken on various types of lights
with regard to wattage, lumens, and life. I'll probably collect
price data eventually but it isn't that important to me.

(Interesting set of data follows) I recently discovered the Syvania "Capsylite" line of quartz/halogen bulbs. These are interesting products because they are interchangeable with standard incandescants, but are appreciably more efficient, longer lived, and (I believe) have better color. Because they use a double shell of glass, they are also insensitive to finger oils, and do not present the same risk of burns when at operating temperature. As a drop in replacement for incandescant, these bulbs are very nice indeed: Type W Lumens Color L/W Maker Model Life QH 42 665 15.8 Sylvania CAP 3500 > I 40 505 12.6 1000 QH 52 885 17.0 Sylvania CAP 3500 > I 60 870 14.5 1000 QH 72 1300 18.0 Sylvania CAP 3500 > I 75 1190 15.9 750 The bulbs are available in 120 and 130 V. versions, plus some set of floods and spots (52 and 72 Watts I think). The ones I purchased cost almost $4.00 each, so they are not cheap, but I have been very happy with them so far. No data at the moment on the 3500 hour lifetimes. Rob Kleinschmidt
