My ringgrip smartglow 6 hour timer globe which is used infrequently (when I go on holidays) has stopped working (no illumination). As I consider that it has not had a lot of work, the question is, is there...
I have three solutions to help you.
1/ The globe may have been bumped or jarred and the filament may be broken
The filament can be repaired.
Look through the small area of clear glass near the neck of the bulb, using a magnifying glass; and a torch at that area and other areas around the globe
to inspect the filament.
With your eye follow the filament connections very slowly from one end to the other,
until you find the break (if any).
Memorise roughly where it has the break in proportion to some reference on the outside of the globe (felt pen mark).
Then insert the globe into a portable corded fitting (mechanics light).
Holding the fitting in your hand, switch it on.
Move your hand around (so the globe is either upside down, left, right, or diagonal, etc),
gently jarring the globe, remembering the position of the break of the filament, try to cause the filament's broken end to touch the terminal where it originally broke off from (doesn't have to be the exact position of the terminal, but in that area).
With a little patience, you may cause it to touch, and when you do, the light will instantly come on, the filament will be repaired (welded back on), and may even outlast any other part of filament breaking in future.
Now the instant it comes on, don't move your hand for a minute or so, to allow it to properly weld, then switch off, allow it to cool, then remove from portable fitting.
2/ If the problem is not the filament, the electronics can also be repaired.
They are located in the bayonet part of the globe,
and are the second cause of failure.
A skilled technician can access and repair that area
for only $10 grand.
3/ A more economical remedy, however, is to hold the globe upside down
in your hand,
then slowly release it from a twenty storey window.
Hope one of these helps !
