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

Sylvania ;-) >These are interesting products because they are interchangeable with standard >incandescants, but are appreciably more efficient, longer lived, and >(I believe) have better color. They are nice. VERY white. As far as colour goes, the big advantage is that they don't go orangey on you with a dimmer. They are also considerably smaller than their incandescent counterparts (as floods that is). The difficulty with them in pot lamps is that since they're smaller, they are more recessed into the fixture, and the fixture tends to narrow the flood. >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. H'm, my 50W floods get pretty darn hot. Not as hot as bare QH, but can still do some damage. >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. I bought 9 of them at a good electrical supplier (who's prices are usually very good) and got a discount. Only $12.50 apiece. (Only in Canada eh?). QH floods are more typically $17+. I ran the 9 for about 6 months before we sold the house (and salvaged the bulbs! At $12.50 apiece you think of these things!). One died fairly early (a mechanical defect actually), the others were fine. We'll be reinstalling them here outdoors probably. -- Chris Lewis, Phone: (613) 832-0541 UUCP: uunet!utai!lsuc!ecicrl!clewis Moderator of the Ferret Mailing List (ferret-request@eci386) Psroff mailing list (psroff-request@eci386)
