what should i check when a short double-ended halogen bulb stops lighting?
a failed short halogen lamp may be replaceable where the fitting permits owner access. burnt contacts, broken protective glass or repeated failures need the fitting assessed first.
disconnect power as instructed and let it cool fully. do not work at an unsafe height, bend contacts, force the glass or remove an electrical enclosure.
the linked guide concerns 78 mm R7s J78 lamps rated 150 W, 220-240 V. match all those requirements and the fitting's maximum rating, not just the double-ended shape. the two-pack provides a spare, not permission to change the fitting. keep fingers off new halogen glass and secure intact protective glass before restoring power. a correct lamp that does not seat, stays dark or fails again calls for a qualified repairer.
first checks
- compare the cold fitting's rating
use accessible markings and the manual to check length, R7s base, voltage and permitted wattage before touching the lamp.
