Garage door opener

[xe1yzy]

Hi guys...

My Garage door opener burns quite often the ligth bulb, they last only one or two weeks, I even change for a flourecent light , but same happens...

any Idea to improve the light bulb life?

Have a good weekend !

Maybe it is the vibration.  Try using a bulb designed to work under more strenuous conditions.  Like special application bulbs made for a trouble/work lights or ones made for ceiling fans.

Modern standard lightbulbs are not designed to take much vibration when they are hot. Yes bulbs designed for rough service or fan service have sturdier filaments with extra supports and can better deal with a vibrating environment. Also how long does the operator leave the light on, remember a standard 100 watt bulb has a design life of 750 hours or so. Lower wattage bulbs have longer design lives.

Well if it was me, I'd op for a change altogether, i'd leave that circuit intact and use the Switch to actuate a better circuit involving two 100 watt lamps mounted in another location  side by side on the ceiling say 5 foot apart and light the area up even better, heck mounting hardware and boxes an such are relatively inexpensive, and what little wire wouldn't amount to much and you'd have Better lighting...I never liked those lamps incased in those systems anyways, bad heat disapation, pain the butt to get too, i just don't like that set up...

Seems to me It would take a wicked amount of vibration to kill a bulb in 1 or 2 weeks and the fluorescent replacement didn't last any better. I think I would find an older analog volt meter to test the line voltage first. If the static line voltage is right, put a new bulb in and check the voltage at the bulb socket. Watch for spikes. It may be the motor start or stop is causing a spike at the bulb socket as the field collapses. Also look to see if the ac line neutral is properly attached.

Somebody makes a gizmo that fits under a bulb in a light socket that softens the surge when the bulb  is switched on. The maker clamed extended bulb life. I suspect some sort of soft start circuit. This gizmo may cost a few bucks and unless the voltage is stable may end up in the same bin as the old bulbs. It may just need a new cap. Good luck. Let us know what you find.

You may want to try an easier alternative. Install an appliance or outdoor service bulb. Most of these are designed a little more heartier than the garden variety light bulb. Most of the time they can withstand the vibration too.

We use 130V bulbs here. We get them at the regular hardware store.  They last for months and months, maybe even 9 months or more. They're 10% more dim than a normal 120V bulb, but who cares?   I use 'em everywhere.

Fix it the way I did. Remove the bulb and screw in a threaded plug adapter. Make up a 4 foot lamp cord with a plug and socket. Hang the socket from the ceiling with a bulb and plug the cord into the machine. No problems since.

Thanks to all...

Well, the problem is solved, following your ideas I put a plug adapter, and a lamp fixture  right to the garage celling, to avoid the motor vibration, also I put a small relay for take any spike, now the light bulbs take the power in another source...

well lets see if this works and last !

Thanks a lot guys!

Well FB WE hope everything works out there OM..
