Standard lightbulbs are available in a 130 volt rating, as opposed to the normal 120 volt rating. Operating a 130 volt lamp at 120 volts does not appreciably lower the light output, but seems to appreciably increase lamp life (as compared to 120 volt lamps). I have used 130 volt lamps in outdoor lights around my house and in vapor-tight fixtures in my barn for a number of years with excellent results. These lamps seem to take the thermal shock much better than a 120 volt lamp (like when an outdoor lamp is turned on at 0 degrees F.). I have also tried lamps rated as "rough service" lamps, but have had much better luck with the 130 volt variety for outdoor use. Believe it or not, I have 130 volt lamps in my barn which are over six years old. I specifically chose the 130 volt lamps for use in guarded, vapor-tight fixtures, because it is a pain in the you-know-what to change lamps in that type of fixture. You can get 130 volt lamps from any wholesale electrical supply firm (which will generally sell to anyone over-the-counter on a cash basis). The price is about the same as for regular 120 volt lamps. ==> Larry Lippman @ Recognition Research Corp., Clarence, New York ==> UUCP {bbncca|decvax|rocksanne|rocksvax|watmath}!sunybcs!kitty!larry ==> VOICE 716/688-1231 {rice|shell}!baylor!/ ==> FAX 716/741-9635 {G1, G2, G3 modes} seismo!/ ==> "Have you hugged your cat today?" ihnp4!/
